Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the name of the sugar that is produced during the dark stage of photosynthesis?
A
Sucrose
B
Glyceraldehyde 3 phosphate
C
Glucose
D
Lactose
Explanation: 

Detailed explanation-1: -One molecule of glyceraldehyde-3 phosphate is created in three turns of the Calvin cycle. Two molecules of glyceraldehyde-3 phosphate combine together to form one glucose molecule.

Detailed explanation-2: -Glucose is the end product of the dark reaction.

Detailed explanation-3: -ATP and NADH donate electrons to the 3-carbon molecules, which are converted into a 3-carbon sugar called glyceraldehyde-3-phosphate (G3P).

Detailed explanation-4: -The Calvin cycle takes place in the stroma and uses the ATP and NADPH from the light-dependent reactions to fix carbon dioxide, producing three-carbon sugars-glyceraldehyde-3-phosphate, or G3P, molecules.

Detailed explanation-5: -Used by the majority of plants, it involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become a sugar called glucose.
