What is difference between cyclic photophosphorylation and Noncyclic photophosphorylation?
Non-cyclic photophosphorylation produces 1 ATP and 2 NADPH2 molecules….Difference Between Cyclic and Noncyclic Photophosphorylation.
| Cyclic Photophosphorylation | Non-Cyclic Photophosphorylation |
|---|---|
| Electrons tend to pass in a cyclic manner. | Electrons tend to pass in a non–cyclic manner. |
What is Z scheme write any two differences between cyclic photophosphorylation and non-cyclic photophosphorylation?
Difference between Cyclic and Non-Cyclic Photophosphorylation
| Cyclic Photophosphorylation | Non-Cyclic Photophosphorylation |
|---|---|
| Water is not required. | Photolysis of water is present. |
| NADPH is not synthesized. | NADPH is synthesized. |
| Oxygen is not evolved as the by-product | Oxygen is evolved as a by-product. |
What is the difference between the cyclic and noncyclic pathways of photosynthesis?
1 Answer. Cyclic photo-phosphorylation in photosynthesis light dependent reaction leads to the formation of ATP and NADPH, and the electrons go from water to PSII to PSI and eventually to NADPH. In non-cyclic photo-phosphorylation only some ATP is produced and the electrons go from PSII to PSI and back again.
What is the difference between ps1 and ps2?
Answer: Photosystem I (PS I) and photosystem II (PS II) are two multi-subunit membrane-protein complexes involved in oxygenic photosynthesis. The main difference between photosystem 1 and 2 is that PS I absorbs longer wavelengths of light (>680 nm) whereas PS II absorbs shorter wavelengths of light (<680 nm).
What is the difference between respiration and photorespiration?
Hint: Respiration is the process in which intake of oxygen and release of carbon dioxide happen and photorespiration is the process in which the enzyme RuBisCo oxygenates RuBP by wasting the energy produced by photosynthesis.
What is cyclic and non cyclic process?
A cyclic process consists of a series of changes which return the system back to its initial state. In non – cyclic process the series of changes involved do not return the system back to its initial state.
Why is it called Z scheme?
Why is it called Z-Scheme? It is simply because the diagram, when first drawn, was in the form of the letter “Z”.
What are the difference between light reaction and dark reaction?
What is the difference between light and dark reaction? The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.
What is the difference between C3 and C4 pathway?
C3 plants use the C3 pathway or Calvin cycle for the dark reaction of photosynthesis. C4 plants use the C4 pathway or Hatch-Slack Pathway for the dark reaction of photosynthesis. These plants are cool-season plants, commonly found in cool and wet areas. These plants are warm-season plants, commonly found in dry areas.
What are the similarities between cyclic and non cyclic electron transport during photosynthesis?
Similarities Between Cyclic and Noncyclic Photophosphorylation. Both cyclic and noncyclic photophosphorylation occur during the light reaction of photosynthesis. Cyclic and noncyclic photophosphorylation are two types of ETS. Both cyclic and noncyclic photophosphorylation are light-dependent.
What is the difference between photosystem 1 and photosystem 2 Class 11?
PS-I absorbs a longer wavelength of light of 700nm whereas PS-II absorbs 680nm which is a shorter wavelength of light. > Photosystem I use light to convert NADP+ to NADPH2 in the presence of chlorophyll and other pigments. Photosystem II absorbs light and transfers electrons from water to plastoquinone.
What is cyclic photophosphorylation?
Cyclic photophosphorylation can be defined as the synthesis of ATP coupled to electron transport activated by Photosystem I solely, and can therefore proceed in long-wave-length light (03BB 2265 700 nm). This proces is unaffected by the specific inhibitors of Photosystem II, such as CMU, DCMU and orthophenanthroline.
What is the difference between cyclic and noncyclic photophosphorylation?
Ans. The differences between cyclic and noncyclic photophosphorylation include Cyclic photophosphorylation happens only in the photosystem I but non-cyclic photophosphorylation occurs in both the photosystems I and II.
Why PS II is not involved in cyclic photophosphorylation?
PS II is not involved in cyclic photophosphorylation. Hence, water is not involved in this process; as a result, cyclic photophosphorylation does not generate molecular oxygen as a byproduct. Since the electrons return to the PS I, no reducing power is generated (no NADPH) during the cyclic photophosphorylation.
What is cyclic photophosphorylation in plants?
What is Cyclic Photophosphorylation. Cyclic photophosphorylation refers to the synthesis of ATP during the light reaction of photosynthesis, coupling to a cyclic passage of electrons to and from photosystem I (P700). Thus, only a single type of photosystem is involved in cyclic photophosphorylation.
What is the final electron acceptor of cyclic and noncyclic photophosphorylation?
Cyclic Photophosphorylation: The final electron acceptor of the cyclic Photophosphorylation is P700. Noncyclic Photophosphorylation: The final electron acceptor of the noncyclic photophosphorylation is NADP +.
