Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The purpose of The Calvin Cycle is to ____
A
Fix Carbon
B
Synthesize Glucose Molecules
C
Metabolize Water Molecules
D
Metabolize Carbon Dioxide
Explanation: 

Detailed explanation-1: -Calvin cycle is also known as the C3 cycle. It is the cycle of chemical reactions where the carbon from the carbon cycle is fixed into sugars. It occurs in the chloroplast of the plant cell.

Detailed explanation-2: -The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow. Every living thing on Earth depends on the Calvin cycle. Plants depend on the Calvin cycle for energy and food.

Detailed explanation-3: -The Calvin Cycle uses the NADPH and ATP from the Light Reactions to “fix” carbon and produce glucose. Carbon dioxide enters the Calvin Cycle when Rubisco attaches it to a 5-carbon sugar. Most plants fix CO2 directly with the Calvin Cycle, so they are called C-3 plants.
