Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which one is produced during the light independent reactions?
A
ATP
B
NADPH
C
Glucose
D
Water
Explanation: 

Detailed explanation-1: -The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO2 and create a product that can be converted into glucose. The ultimate goal of the light-independent reactions (or Calvin cycle) is to assemble a molecule of glucose.

Detailed explanation-2: -Light-independent reaction (biology definition): Light-independent reaction is a series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide.

Detailed explanation-3: -Twelve molecules of 3-Phosphoglycerate (3PG) are the products of this reaction. Energy from ATP and NADPH reduce the 3PG molecules to form another 3 carbon compound, glyceraldehyde-3-phosphate (G3P). Two G3P molecules are removed from the cycle and ultimately become one glucose molecule.

Detailed explanation-4: -Photosynthesis, a fundamental light-dependent reaction in plants that takes in carbon dioxide from the air, along with water, and light to produce glucose as a source for plant growth. The C6H12O6 is the glucose. This reaction requires light for it to proceed.

Detailed explanation-5: -The light independent reactions or the dark reactions is the Calvin cycle. In the light independent reaction carbon dioxide from the environment is fixed to form sugars. However the energy necessary for this carbon fixation and the subsequent production of a three carbon sugar requires the light dependent reactions.
