How organism use the energy- rich molecule in the photosynthesis?
During photosynthesis, organisms use energy from sunlight to convert carbon dioxide and water into glucose, a high energy molecule. This glucose is then used by the organism for energy production, growth, and maintenance of cellular processes. Essentially, photosynthesis allows organisms to harness and store energy from sunlight in the form of glucose.
Why are the two things produced by photosynthesis important?
Glucose and Oxygen are produced from Water and Carbon Dioxide. The equation is: 6CO2 and 6H2O makes C6H12O6 and 6O2. The glucose is used for energy for the plant and helps it to grow. The Oxygen is not needed by the plant so it is breathed out by the plant through the Stomata and then we can breathe the Oxygen in and breathe out Carbon Dioxide for the plants. The 2 things are important because without glucose the plant would not be able to grow and without Oxygen we and all other animals on Earth would not be alive.
Is the cellular respiration process more complex than its equation?
Yes, cellular respiration is more complex than its equation. The process involves multiple steps and complex biochemical reactions that occur in different cellular compartments, such as the cytoplasm and mitochondria. The equation, while accurate in summarizing the overall process, does not fully capture the intricacies and regulatory mechanisms involved in cellular respiration.
What is the name of pigment present in carrots which impart orange colour to it?
The pigment present in carrots that imparts their orange color is called beta-carotene. Beta-carotene is a type of carotenoid, which is a group of pigments that are responsible for the red, orange, and yellow colors found in many fruits and vegetables.
The maximum amount of energy that our sun gives out is in the yellow range of the spectrum, therefore it has been to the advantage of algae (and all other photosynthetic organisms) to specialize in this particular frequency. Ultra-violet has more energy of course but as the atmosphere filters out much of this it isn't energy efficient to specialize in this colour. There is lots of infra-red radiation around but it is of a low energy quantum and therefore doesn't give a high 'energy return' on being absorbed.
Now there are some organisms that do utilized both infra-red and ultra violet. Extremeophilles that live in volcanic geysers use heat (IR) exclusively. Human beings use UV to manufacture their Vitamin D. Algae however is a yellow range specialist.
What are the two types of phosphorylation that occur during photosynthesis?
Yes. Although the primary function of photosynthesis isn't to create ATP, photophosphorylation does create some ATP molecules which the plants can use in addition to those made in the mitochondria.
What substances is transported from leaves to the rest of the plant body?
Sugars (mainly glucose) produced through photosynthesis in the leaves are transported to the rest of the plant body for energy and growth. Additionally, water and minerals absorbed by the roots are also transported to the leaves through the xylem tissue.
How does light and dark reactions takes place?
The light dependent reaction occurs in the chloroplast. In the light dependent reaction, chlorophyll pigments absorb solar energy. This energy is then converted into a chemical form (not glucose). The water molecule is split into oxygen and hydrogen molecules.
The dark reaction or the carbon fixation period occurs in the fluid matrix or stroma of chloroplast. The hydrogen product from the first reaction is combined with the carbon dioxide molecules to makes sugars. This results in the C3 or C4 cycle.
Which of the following is used in photosynthesis by both plants and cyanobacteria?
Chlorophyll is used in photosynthesis by both plants and cyanobacteria. It is a pigment that absorbs light energy and is essential for converting sunlight into chemical energy during the photosynthetic process.
What are the byproducts of the process photosynthesis?
The main byproducts of photosynthesis are oxygen and water. During the process, plants absorb carbon dioxide from the atmosphere, convert it into glucose for energy, and release oxygen as a waste product.
Why is it not advisable to sleep in a closed room with shouldering fire in it?
During daytime plants have photosynthesis, which enables them to consume and convert atmospheric CO2 into O2, while during night reverse happens as photosythesis can not take place due to absence of sun light. Plants breathe in which CO2 is exhaled while O2 is consumed.
So, if someone sleeps in an enclosed room with plants, the level of CO2 may go beyond tolerable level of humans, which might eventually suffocate and kill humans. That is why we are adviced not to sleep in enclosed room full of plants.
Why does photosynthesis not take place in the parts of leaves that are white?
The green areas of a leaf contain the type of chlorophyll that is responsible for the process of photosynthesis and which is colored green. It is absent from some areas and those leaf parts are therefore not green and photosynthesis cannot occur there.
How does leaf take in water to perform photosynthesis?
Leaves take in water through their roots and transport it to the cells in the leaves through specialized tissues called xylem. Once in the leaves, water is used in photosynthesis to produce glucose and oxygen with the help of sunlight and carbon dioxide. This process occurs in the chloroplasts of the leaf cells.
What part the photosynthetic cycle produces glucose and ADP?
The Calvin cycle is the part of photosynthesis that produces glucose by fixing carbon dioxide into organic molecules. In this process, ADP is converted to ATP to provide energy for the synthesis of glucose.
How stress affect photosynthesis and respiration?
Homeostasis and Thermodynamics of Metabolic Pathways:
Metabolism is a largely circular process of energy conversion in cells of living organisms. Chemical energy is extracted from nutrients (catabolism) and this energy is in turn used to synthesize new molecules (anabolism) from the same type of nutrients to maintain the structure and function of an organism. To accomplish both, say energy extraction from and biosynthesis of proteins, metabolism of living cells is a spatial and temporal network of chemical reactions close to, but never at chemical equilibrium. Living organisms maintain a state of metabolic homeostasis which can be viewed as a steady-state throughput or flow of energy and metabolites to sustain body functions and structures.
Respiration and photosynthesis are catalytically possible only because of the coordinated activity of hundreds of proteins that belong to deferent sets of pathways in different compartments of cells and/or organisms. Understanding the structural and functional complexity that provides reductive synthesis of glucose as well as oxidative degradation is the same as understanding the mechanism of cellular metabolism.
Cocoa is neither a C3 or C4 plant. Though it tends to live in warmer climates, it does not fit into either category.
What process of photosynthesis can occur even when there is no light?
The Dark Reactions (a.k.a. The Calvin Cycle) can occur without the light. Sometimes they are also called the Light Independent Reactions for that very reason. Light is required during the light reactions because the energy from light (photon) is required to excite electrons. No such energy source is required for the Calvin Cycle because the energy has already been converted into a chemical form (ATP and NADPH) during the light reactions. The energy from ATP and NADPH is used to "drive" the Calvin Cycle (the accumulation of Carbon atoms from Carbon Dioxide). Carbon Dioxide and Rubulose Biphosphate (RuBp) are combined using the enzyme rubisco. The energy from ATP and NADPH is added (in several steps). The final molecule, gyceraldehye-3-phosphate (G3P) is produced. There is a fairly common misconception that glucose is the final product of the Calvin Cycle; but, it is actually G3P. Notice that none of these reactions (those of the Calvin Cycle) required light.
And don't forget, plants don't need light for cellular respiration either.
What converts light energy into chemical energy sugars through the process of photosynthesis?
Chlorophyll, a green pigment found in chloroplasts of plant cells, converts light energy from the sun into chemical energy through the process of photosynthesis. This process involves capturing light energy to produce sugars (such as glucose) from carbon dioxide and water.
How does photosystem II and photosystem allow the Calvin cycle to work?
The products of the photosystems are the reactants for the Calvin cycle.
Students who are using this as a resource for APEX coursework should note that you may want to paraphrase so your teachers can't google your responses :)
What is photolysis and mention its importance in photosynthesis?
Photolysis is any reaction where a chemical compound splited by photon (units of light). In a lay man's language splitting up a chemical compound in presence of light. In photosynthesis photons split water molecule into its constituents and release energy in the form of electrons which are transported to the electron transport chain along electopotential gradient
The reaction is a s follows
H2A + 2 photons (light) 2e- + 2H+ + A
A can be oxygen or in purple sulfur or cyanobacteria can be S
What will happen if the balance between oxygen and carbon dioxide is lost in nature?
If the balance between oxygen and carbon dioxide is lost in nature, it can lead to negative impacts such as reduced oxygen levels for living organisms, changes in climate due to increased greenhouse gases, and disruptions to ecosystems and biodiversity. This imbalance can ultimately threaten the overall health and functioning of the planet.
What three ingredients are need for photosynthesis?
The primary function of photosynthesis is to convert the energy from the sun into chemical energy for food. With the exception of certain plants utilizing chemosynthesis, all plants and animals in Earth's ecosystem are ultimately dependent on the sugars and carbohydrates produced by plants through photosynthesis.
A byproduct of the photosynthetic process is the release of oxygen into the atmosphere. Like nature's air filter, photosynthesis takes in harmful carbon dioxide, a byproduct of animal respiration, and produces oxygen that can than be used for animal respiration.
Photosynthesis converts sunlight into chemical energy in the form of sugar. That sugar is then broken down through cellular respiration to fuel life at the cellular level. We breathe oxygen and exhale carbon dioxide, while plants breathe carbon dioxide and exhale oxygen. Photosynthesis is therefore the ultimate source of the food we eat and the air we breathe.
What are the reactants and products in the processs of photosynthesis?
Recants-carbon dixode and water
Products-high-energy sugars and oxygen
