What will be the result of photosystemII being exposed to less sunlight?
The thylakoid will have fewer hydrogen ions. For Apex
I am guessing a bit here, but sugar molecules are produced in plants and plants get their carbon atoms from carbon dioxide gas in the atmosphere.
Where is photosynthesis located in plants?
Photosynthesis in plants primarily takes place in the chloroplasts, which are specialized organelles found in the cells of plant leaves. Chloroplasts contain chlorophyll, a green pigment that captures sunlight energy and converts it into chemical energy through the process of photosynthesis.
During the light-dependent reaction of photosynthesis, light energy is used to split water molecules to produce oxygen, ATP, and NADPH. These products are then used in the light-independent reaction (Calvin Cycle) to convert carbon dioxide into glucose.
What are the main energy storing products of each phase of photosynthesis?
The main energy-storing product of the light-dependent phase of photosynthesis is ATP (adenosine triphosphate) and NADPH. In the light-independent phase, the main energy-storing product is glucose.
The electron carrier in photosynthesis that donates electrons to CO2 for its conversion into sugar is NADPH (nicotinamide adenine dinucleotide phosphate). NADPH is produced during the light-dependent reactions of photosynthesis and transfers high-energy electrons to the Calvin cycle to facilitate the fixation of CO2 into sugar molecules.
What are four substances are recycled during photosynthesis and respiration?
Oxygen, Carbon Dioxide, water, and ADP/ATP are all recycled during photosynthesis and respiration. Energy is not recycled so there must be a continuous supply of energy to maintain the cycle.
What happens to oxygen ATP and NADPH doing reactions?
During reactions such as photosynthesis, oxygen is produced as a byproduct, ATP is generated as the energy currency for the cell, and NADPH is utilized as a reducing agent to drive various metabolic processes. Oxygen is released into the atmosphere, ATP is used to power cellular activities, and NADPH helps in biosynthetic pathways and other cellular processes.
Where does the water enter the plant in photosynthesis?
The water for photosynthesis comes from water that is absorbed from the soil by the roots of the plant and transported upward to the leaves through the vessels called xylem.
Refer to the related link for an illustration of the materials for photosynthesis and where they come from.
What is the plant cell organelle that is responsible for photosynthesis?
The chloroplast is the organelle responsible for photosynthesis in plant cells. It contains pigments like chlorophyll that capture sunlight and convert it into energy through a series of biochemical reactions.
What is captured by the chemical ribulose bisphosphate?
Ribulose bisphosphate captures carbon dioxide molecules in the process of carbon fixation during photosynthesis. It is a key molecule in the Calvin cycle, where it combines with carbon dioxide to form an unstable six-carbon compound that eventually leads to the production of sugars.
Is chlorophyll pigment present in red amaranths?
Yes, red amaranths contain chlorophyll pigment, but the red color comes from additional pigments called betalains found in the plant. Chlorophyll is responsible for the green color in plants and plays a crucial role in photosynthesis.
How does the light color affect photosynthesis?
Phototropism is the tendency of plants to move toward a light source.
for instance, plant an avocado seed and watch how the stem and leaves will turn toward the brightest light. If you leave it stationary, do not turn it, the plant will begin to bow in that direction.
The color of light may have little actual affect on most plants, however some plants that are more suited for darker environments may move more slowly to some lights and more quickly to others.
Why does the carbon cycle begin with photosynthesis in plants?
The carbon cycle begins with photosynthesis in plants because plants take in carbon dioxide from the atmosphere during photosynthesis to produce glucose, which forms the basis of their energy and growth. This process converts atmospheric carbon dioxide into organic carbon, making it available for the rest of the ecosystem.
What is the main product of camiguin?
The main product of Camiguin is lanzones, a small sweet fruit with a translucent flesh and a thick, rough skin. Camiguin is known as the "Lanzones Capital of the Philippines" due to the abundance and quality of lanzones produced on the island.
How is photosynthesis an cellular respiration different?
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy (glucose) using carbon dioxide and water, releasing oxygen as a byproduct. Cellular respiration, on the other hand, is the process by which cells break down glucose molecules to produce ATP energy, releasing carbon dioxide and water as byproducts. Essentially, photosynthesis captures energy and stores it in glucose, while cellular respiration releases energy from glucose.
What is the source of H for the Calvin cycle in photosynthesis?
The source of hydrogen (H) for the Calvin cycle in photosynthesis comes from water molecules. During the light-dependent reactions, water is split by the enzyme complex in the thylakoid membrane, releasing oxygen, protons (H+), and electrons. The electrons are then used to reduce NADP+ to NADPH, providing the reducing power needed for the Calvin cycle to convert carbon dioxide into carbohydrates.
How is a plant cell specialized for photosynthesis at the molecular level?
Plant cells are specialized for photosynthesis due to the presence of chloroplasts, which contain specialized pigment molecules like chlorophyll that absorb light energy. These pigment molecules are embedded in the thylakoid membranes where the light-dependent reactions of photosynthesis occur, leading to the production of ATP and NADPH for the Calvin cycle. Additionally, plant cells have a large central vacuole that helps regulate water balance and maintain turgor pressure necessary for photosynthesis to proceed efficiently.
Where is the Suns energy stored in the process of photosynthesis?
The Sun's energy is stored in the form of chemical energy in the bonds of glucose molecules produced during photosynthesis. This energy can be later released when needed by the organism for various metabolic processes.
When did photosynthesis evolve?
Plants that mutated to have photosynthesis were able to survive and therefore reproduce, passing on it's genes. Plants (assuming they are not carnivorous) that didn't have photosynthesis died, as they cannot move to collect food, so it cannot reproduce and pass on it's genes.
What are some of the factors that affect the rate of photosynthesis?
Factors that affect the rate of photosynthesis include light intensity, carbon dioxide concentration, temperature, water availability, and the presence of chlorophyll and other pigments. Changes in any of these factors can influence the rate at which plants can convert light energy into chemical energy.
How are photosynthesis and cellular respiration related(apex)?
Thus, during photosynthesis a plant consumes water, carbon dioxide, and light energy, and produces glucose and oxygen. The sugar glucose is important because it is necessary for cellular respiration.
Is there starch in purple leaves?
Yes, purple leaves can contain starch, as starch is a common carbohydrate storage molecule in plants. Starch can be found in the chloroplasts of plant cells, where it is used for energy storage and can contribute to the purple coloration of leaves.
Does the stomata on a leaf have to be open or closed during the Calvin benson cycle?
The stomata better be open so that plenty of carbon dioxide diffuses into the leaf and feeds into the Calvin cycle and makes sugars, specifically glyceraldehyde-3-phosphate.
