Q. What is the advantage of light reactions producing ATP and NADP$H_{2}$ on stromal side of thylakoid membrane?
A) Calvin cycle consumes ATP and NADP$H_{2}$ from stroma
B) Light reaction occurs in stroma
C) Dark reaction occurs in grana need ATP + NADP$H_{2}$
D) $CO_{2}$ is produced in stroma
Explanation
Energy formed on the stroma side thylakoids membrane during light reaction, i.e., NADPH $+ H^{+}$ of ATP, is used by the Calvin cycle or dark reaction to form the starch or carbohydrates
