Does the biosynthetic phase of photosynthesis directly depend on light?

Step-by-step solution

The products of light reaction are ATP, NADPH and O2 . Of these O2 diffuses out of the chloroplast while ATP and NADPH are used to drive the processes leading to the synthesis of food, more accurately, sugars. This is the biosynthetic phase of photosynthesis. This process does not directly depend on the presence of light but is dependent on the products of the light reaction, i.e., ATP and NADPH, besides CO2 and H2O. Immediately after light becomes unavailable, the biosynthetic process continues for some time, and
