Which one of the following is not true about the light reactions of photosynthesis? |
|
a) |
Light energy provides energy for the photolysis of water through excitation of the reaction centre of PS-II |
b) |
The flow of electrons from water to NADP in non-cyclic electron transport produces one ATP |
c) |
Reactions of the two photosystems are needed for the reduction of NADP |
d) |
and are the reaction centres of PS-I and PS-II respectively |

(d) In photosystem-I, the photocentre is a special chlorophyll-a molecule called , which is active in both red and far-red light, while a very small amount of special from of chlorophyll-a called , constitutes the reaction centre of photo system-II. PS-II is inactive in far-red light (beyond 680 nm). |
