Photosynthesis
This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.
6,415 Questions
For the light dependent phase of photosynthesis all you need is sunlight and water as the inputs. The output is pure hydrogen (H+, protons) and oxygen. The protons are in the form of a hydrogen gradient, which is converted to ATP by the ATPase enzyme.
Water is important because it provides the electrons lost when the sunlight is converted to chemical energy. The products after water is 'split' are the protons previously mentioned and oxygen.
What are the three organisms that carry out photosynthesis?
The three main organisms that carry out photosynthesis are plants, algae, and cyanobacteria. They are capable of converting light energy into chemical energy stored in glucose through the process of photosynthesis.
What picks up energized electrons from reactions in the thylakoids of plants during photosynthesis?
The molecule that picks up energized electrons in the thylakoid membranes during photosynthesis is called NADP+ (nicotinamide adenine dinucleotide phosphate). It accepts the electrons and is reduced to NADPH, which then carries the electrons to the Calvin cycle for the production of sugars.
The raw materials plants use for photosynthesis?
Plants use carbon dioxide and water as raw materials for photosynthesis. These raw materials are converted into glucose and oxygen with the help of sunlight and chlorophyll. The process of photosynthesis allows plants to produce their own food and release oxygen into the environment.
What is Raw material of a polystyrene cup?
The raw material of a polystyrene cup is polystyrene plastic, which is derived from styrene, a petroleum-based hydrocarbon. The polystyrene undergoes a process called extrusion or injection molding to form the shape of the cup.
What goes in and out of the photosynthesis process?
Carbon Dioxide + Water (+ Energy from sunlight) ---> Oxygen + Glucose
or
6CO2 + 6H20 (+ Light energy) ---> 6O2 + C6H12O6
What waste product of photosynthesis is released to the environment?
It is the gas oxygen. It produced by photolysis of water
During photosynthesis water molecules are split into atoms of oxygen and what?
Since water is comprised of two hydrogen atoms and one oxygen atom, when it is split into atoms by plants during photosynthesis the only other atoms other than oxygen that are produced are hydrogen atoms.
Photosynthesis is useful in three respects.
1. It is the only process that convert simple elements (carbon dioxide and water) with the aid of sunlight into glucose and Oxygen. This provides food for the plant and in turn food for animals; both of which are then eaten by people.
2. People and animals benefit directly from the products of plants (without photosynthesis no plants): foods, drink, building materials, fuel, medicine.
3. Carbon dioxide is a byproduct of animal respiration, plants convert the Carbon dioxide back into breathable Oxygen (as a byproduct) - without plants we eventually would not be able to breath.
No, chlorophyll is not a steroid. Chlorophyll is a green pigment found in plants and algae that plays a role in photosynthesis, while steroids are a class of lipids with a different chemical structure and function in the body.
What energy transformations take place during photosynthesis?
During photosynthesis, light energy is converted into chemical energy in the form of glucose. This process involves the transformation of electromagnetic energy (light) into chemical energy stored in the bonds of glucose molecules.
What makes peat and can be used to treat burns bee stings and to polish objects?
Moss or peat moss can be used to treat burns, bee stings, and to polish objects. Peat moss was also used to heat homes in early settlement days of the western United States.
How does friction affect energy transformations?
It cause degradation of energy transformation. In other word, it loss the efficiency through friction.
How does enzyme action affect the rate of photosynthesis?
Enzymes play a crucial role in photosynthesis by facilitating the chemical reactions that convert carbon dioxide and water into glucose and oxygen. The rate of photosynthesis can be influenced by the availability and efficiency of enzymes involved in key steps of the process, such as Rubisco, which is involved in carbon fixation. Changes in enzyme activity, such as through temperature or pH fluctuations, can impact the overall rate of photosynthesis in plants.
What does not belong NADP plus chlorophyll or pigment?
NADP+ does not belong because it is not a molecule directly involved in photosynthesis. Chlorophyll and other pigments are essential for capturing light energy during photosynthesis. NADP+ is involved in the transfer of electrons during the later stages of photosynthesis.
Where do the carbon hydrogen and oxygen in triose phosphate originate from?
The carbon atoms come from the Ribulose biphosphate and CO2 fixation. The oxygen also comes from CO2 fixation. The hydrogen comes from the oxidation of NADPH (which was produced in the light-dependent reaction)
What creates the energy used in photosynthesis?
The energy used in photosynthesis comes from sunlight. Light energy is absorbed by chlorophyll and other pigments in the chloroplasts of plant cells, which then use this energy to convert carbon dioxide and water into glucose and oxygen.
What is the name of the reactants of the reaction of photosynthesis?
The reactants of photosynthesis are carbon dioxide, water, and the presence of light energy. The products are glucose or C6H12O6 and oxygen.
How van Niels hypothesis contrubuted to your knowledge about photosynthesis?
Until Van Niels hypothesis, the current theory was that CO2 was split and it was this splitting that produced the O2 in photosynthesis. He found two main things the did not support this theory. He posited that O2 was from H20 breakdown.
1. Van Niel studied photosynthesis in anaerobic bactera and found that they use the carbon in CO2 to produce carbohydrates, but do not release O2. In these bacteria CO2 is not split into carbon and oxygen, so why should aerobic plants be an exception?
2. He studied a photosynthetic bacteria that split H2S (hydrogen sulfide) to make carbohydrates. And proposed that all photosynthetic organisms require a hydrogen source. In plants H20 is the hydrogen source and a source of electrons in PSII, O2 is just the byproduct of the H20 breakdown.
Why are plants and animals important?
Plants are important because the start the food chains and food webs. Plants also give oxygen to oxygen breathing organisms and clean up the air of deadly gases such as carbon dioxide. Animals are important because they keep the food webs and chains in line and they each have their own helpful niche (Niche- the full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions). I hope this helped you a lot if you need anymore answers just ask!!
How does wind affect photosynthesis?
Wind can increase the rate of photosynthesis by helping to disperse carbon dioxide around the leaves, which is a necessary component for photosynthesis. However, strong winds can also lead to excessive water loss from the leaves through transpiration, which can reduce photosynthetic efficiency. Overall, a moderate amount of wind can be beneficial for photosynthesis by aiding in gas exchange and preventing heat buildup.
How is the process of photosynthesis central to sustaining life on earth?
Photosynthesis is critical as it converts sunlight, water, and carbon dioxide into glucose and oxygen, providing energy for plants and releasing oxygen into the atmosphere. This process is the foundation of the food chain, as plants are the primary producers that support all other life forms. Without photosynthesis, the Earth would not have enough oxygen and energy to sustain life as we know it.
