Question

Differences between photophosphorylation (PP) and oxidative phosphorylation (OP) is

• A. In PP, synthesis is of ATP while in OP it is of ADP.
• B. In PP, oxygen is evolved while in OP oxygen is taken up.
• C. Both cannot take place in light.
• D. PP can take place in green leaves while OP cannot occur in green leaves.

Answer 1

Answer: (B)

In PP, oxygen is evolved while in OP oxygen is taken up.

Both the oxidative phosphorylation and photophosphorylation are in which cells make energy in the form of ATP, oxidative phosphorylation occurs during cell respiration and photophosphorylation occurs during photosynthesis. Oxygen is released during photophosphorylation and oxygen is taken up.

So the correct option s 'In PP, oxygen is evolved while in OP oxygen is taken up'.
