Q. No.| Assertion (A): | For evolution of O2 in photosynthesis, PS-II is required. |
| Reason (R): | PS II is reduced by pulling electrons from water due to which photolysis of H2O occurs. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |
Read the following four statements a,b,c and d and select the right option having both correct statements:
(a) Z scheme of light reaction takes place in presence of PSI only
(b) Only PS I is functional in cyclic photophosphorylation
(c) Cyclic photophosphorylation results into synthesis of ATP and NADPH
(d) Stroma lamellae lack PSII as well as NADP reductase
Options :
1. (c) and (d)
2. (b) and (d)
3. (a) and (b)
4. (b) and (c)
Read the following four statements a,b,c and d and select the right option having both correct statements
Statements :
a. Z scheme of light reaction takes place in presence of PSI only
b. Only PS I is functional in cyclic photophoshphorylation
c. Cyclic photophosphorylation results into synthesis of ATP and NADPH2
d. Stroma lamellae lack PS II as well as NADP
Options :
1. B and D
2. A and B
3. B and C
4. C and D
Statement I: In photosynthesis, the membrane system is responsible for the synthesis of ATP and NADH in carbon reaction
Statement II: In photosynthesis, enzymatic reactions synthesize sugar and which in turn form starch. These reactions are driven by light
