Question

Temperature affect more in :
1) Light reactions than dark reaction
2) Dark reactions than light reaction
3) Photophosphorylation than calvin cycle
4) Cyclic photophosphorylation than non-cyclic photophosphorylation

Answer 1

option (b)

Explanation:

Light reaction just needs a particular wavelength for the PS1 aur PS2 activation.No role of temperature as such.Also,NADP reductase is the only enzyme involved here.

whereas,in dark reaction,it is mainly driven by enzymes which are temperature dependent.

So (b) i guess
