In this process which of the following play important role?

1 Chlorophyll

2 Light energy

3

{Ca}^{+ +}, {Mn}^{+ +}, {Cl}^{-}

4 All of the above

Explanation:

D Water undergoes photolysis, which is a crucial step in the light response of photosynthesis. As a by product, water generates $H^{+}$ ions, which decrease ${CO}_{2}$ to make glucose and $O_{2}$ . Chlorophyll and light energy, as well as the presence of the ions ${Ca}^{2 +}, {Mn}^{2 +}$ , and ${Cl}^{-}$ , are necessary for photolysis to occur.

238045 Which of the following is the first compound that accepts carbon dioxide during dark phase of photosynthesis?

1 NADP

2 RuBP

3 Ferridoxin

4 Cytochrome

Explanation:

B In the first step of the calvin cycle 6 molecules of ${CO}_{2}$ from the atomsphere bind with the 6 molecule of the RuBP chemical, which has 5 carbons. With the aid of an enzyme known as RuBP, ${CO}_{2}$ molecules are joined to RuBP with the help of an enzyme RUBISCO.

238047 Cyclic photophosphorylation results in the formation of

1 ATP and NADPH

2 NADPH

3 ATP, NADPH,

O_{2}

4 ATP

Explanation:

D Cyclic photophosphorylation occurs in PSI, reaction center $P_{700}$ absorb the light in the form of photon excited high energy electron and ejected from ground state of the molecule moves uphill and accepted by primary electron acceptor (PEP) i.e.- FRS or Fe-S or Fd.
Cyclic photophosphorylation results is the synthesis of ATP with an electron transport system that is activated by photosystems I. It occurs in the stromal lamella. In this process the system converts ADP to ATP for immediate energy for the cells.

1 A, B

2 B, C

3 A, C

4 B, D

Explanation:

C Substrate-level phosphorylation is a metabolic process that involves the direct transfer of a phosphate group from a substrate to ADP or GDP, producing ATP or GTP as a byproduct. It converting a higher energy product into a lower energy product.
Succinyl-CoA is acted upon by enzyme succinyl-CoA synthetase to from succinate during the kreb's cycle. The reaction releases sufficient energy to form ATP (in plants) or GTP (in animals) by substrate- level phosphorylation. GTP can form ATP through a coupled reaction.

238049 During non-cyclic photophosphorylation, when electrons are lost from the reaction centre at PS II, what is the source which replaces these electrons?

1 Light

2 Oxygen

3 Water

4 Carbon dioxide

Explanation:

C During non-cyclic photophosphorylation, electrons expelled by the excited PS-II photocentre do not return to it. Therefore, it requires an external electron donor and that purpose is served by water. $H_{2} O$ undergo photolysis, and the electrons thus released are picked up by PS-II $(P_{680})$ and handed to PS-I $(P_{700})$ . The non cyclic flow of electron is called $- Z$ - scheme.
