Question

Number of ATP molecules formed from 8 molecules of water due to noncyclic electron transport and subsequent photophosphorylation is

• A. 8
• B. 4
• C. 16
• D. 12

Answer 1

The correct option is C 16

A) 16 ATP molecules are formed when 8 molecules of water are split in noncyclic electron transport and photophosphorylation.

B) 16 molecules of ATP are formed are formed from 8 molecules of water.

C) In noncyclic electron transport and photophosphorylation, 2 ATPs are produced per water molecule split. So, for 8 molecules of water, 2 x 8 = 16 ATPs are formed.
D) 16 molecules of ATP are formed.
So the correct answer is '16'.
