Question
What happens in both respiration and photosynthesis?
A. Triose phosphates are decarboxylated.
B. NADPH is produced.
C. ATP is produced.
D. Electrons pass through ATP synthase.
Markscheme
C
Examiners report
Some candidates wrongly believed that triose phosphates are produced in both photosynthesis and respiration; while others also got the wrong idea that electrons pass through ATP synthase. This question was a very good discriminator.
