Question

There are two parts of photosynthesis--the light reactions and the dark reactions. What is the end product of the dark reactions?
A. Chlorophyll

B. Carbon dioxide

C. Glucose

D. ATP

Answer 1

C. Glucose.
In the dark reactions, hydrogen produced in photolysis is used to reduce CO2 to carbohydrates such as glucose.

Answer 2

Answer: The correct answer is Option C.

Explanation:

Photosynthesis is defined as the process in which plants take up carbon dioxide and water to produce their food in the form of glucose with the help of chlorophyll and in the presence of sunlight. It takes place into two parts: Light reactions and Dark reactions.

Light reactions are light dependent reactions and it produces energy molecules of ATP and NADPH.

Dark reactions are light independent reactions which does not require light but uses ATP and NADPH to produce sugar molecules like glucose, starch, sucrose etc..

Hence, the correct answer is Option C.
