Question

Both photosynthesis and cellular respiration are metabolic processes that occur in eukaryotic cells. Each process involves several steps and chemical reactions.
All of the following occur during the processes of photosynthesis and cellular respiration except

• A. The production of large amounts of ATP.
• B. Oxidation-reduction reactions.
• C. The use of multiple enzymes to catalyze reactions.
• D. An electron transport chain.

Answer 1

Answer: (A)

The production of large amounts of ATP.

Production of large amount of ATP takes place exclusively during respiration. However a small number of ATP is produced during the light reaction of photosynthesis, which is utilized for fixing or reducing CO${}_2$

So, the correct answer is 'The production of large amounts of ATP'
