Question

The quantum yield in photosynthesis is

• A. More than $1$
• B. $1$
• C. Less than $1$
• D. $0$

Answer 1

The correct option is C

Less than $1$

The correct option is C.

Explanation of the correct option:

1. The quantum yield of photosynthesis is a measure of the energetic efficiency of photoautotrophy.
2. The quantum yield for the light reaction in photosynthesis is the number of oxygen molecules evolved by one quantum of light (photons) in the process.
3. As all photons are not about absorbed productively, therefore the quantum yield in photosynthesis is less than $1$

Final Answer: The quantum yield in photosynthesis is less than $1$
