Question

How many ATP equivalents are required to produce one glucose in $C_4$ plants?

• A. $66ATP$
• B. $54ATP$
• C. $18ATP$
• D. $93ATP$

Answer 1

The correct option is B $54ATP$

In C4 plants, for production of one Glucose molecule 12 ATP and 18 energy NADPH${}_2$ are required. One NADPH${}_2$ is equivalent to 3 ATPs. Therefore a total of 54 equivalents of ATP will be required for the production of one glucose unit.

So, the correct answer is '54 ATP'.
