What is photophosphorylation explain?
Photophosphorylation is the conversion of ADP to ATP using the energy of sunlight by activation of PSII. This involves the splitting of the water molecule in oxygen and hydrogen protons (H+), a process known as photolysis.
What is photophosphorylation Class 11?
Photophosphorylation is the process of utilizing light energy from photosynthesis to convert ADP to ATP. It is the process of synthesizing energy-rich ATP molecules by transferring the phosphate group into ADP molecule in the presence of light.
What is photophosphorylation in light reaction?
When light energy is absorbed by pigments and passed inward to the reaction center, the electron in P700 is boosted to a very high energy level and transferred to an acceptor molecule. In fact, it’s called photophosphorylation because it involves using light energy (photo) to make ATP from ADP (phosphorylation).
What is the purpose of photophosphorylation?
Photophosphorylation refers to the use of light energy from photosynthesis to ultimately provide the energy to convert ADP to ATP, thus replenishing the universal energy currency in living things.
Where does photophosphorylation occur?
chloroplasts
Where does photophosphorylation occur? Photophosphorylation is the light-dependent reaction, which occurs in the chloroplasts of the plant cells, specifically, in the thylakoid membranes.
What are the product of Noncyclic photophosphorylation?
Noncyclic photophosphorylation involves both Photosystem I and Photosystem II and produces ATP and NADPH.
What is Z scheme?
The Z-scheme is an energy diagram for electron transfer in the “light reactions” of plant photosynthesis. It applies equally well to photosynthesis by algae and cyanobacteria. The vertical energy scale shows each molecule’s ability to transfer an electron to (i.e., to reduce) the next one from left to right.
What is difference between oxidative phosphorylation and photophosphorylation?
Note: Oxidative phosphorylation occurs in mitochondria and converts chemical energy into ATP….Differentiate between oxidative phosphorylation and photophosphorylation.
| Points | Oxidative phosphorylation | Photophosphorylation |
|---|---|---|
| Site | It occurs in mitochondria | It occurs in chloroplast |
Which is the best description of photophosphorylation?
Photophosphorylation is a process that occurs during photosynthesis in plants. It is the conversion of ADP (Adenosine Diphosphate) into ATP (Adenosine Triphosphate) using light energy. ATP (Adenosine Triphosphate) is the energy currency of life of all living organisms.
What is photophosphorylation most similar to?
ATP synthesis in chloroplasts is called photophosphorylation and is similar to oxidative phosphorylation in mitochondria.
What is the difference between cyclic photophosphorylation and Noncyclic photophosphorylation?
In the cyclic photophosphorylation, only ATP is produced, whereas, in the non-cyclic photophosphorylation both NADPH and ATP are produced. Photolysis of water does not occur in cyclic photophosphorylation, but it occurs in non-cyclic photophosphorylation.
What is difference between photophosphorylation and phosphorylation?
Photophosphorylation is the process of capturing solar energy and converts to chemical energy….Differentiate between oxidative phosphorylation and photophosphorylation.
| Points | Oxidative phosphorylation | Photophosphorylation |
|---|---|---|
| Energy | Chemical energy is converted into ATP | Light energy is converted into ATP |
What does non-cyclic photophosphorylation produce?
Non-cyclic photophosphorylation produces NADPH in addition to ATP (this requires the presence of water) Both NADPH and ATP are required to produce organic molecules via the light independent reactions.
What are characteristics of photosynthesis?
The main characteristics of the first stage of photosynthesis is the the production of hydrogen and energy. The process of photosynthesis happens in two stages the light-dependent reactions and the Calvin cycle (light-independent reactions). It is in the first stage that hydrogen and energy is being produced with the aid of the light energy.
What is a summary of photosynthesis?
In summary, photosynthesis is a process in which light energy is converted to chemical energy and used to produce organic compounds. In plants, photosynthesis typically occurs within the chloroplasts located in plant leaves.
