What is C6H12O6-sugar produced in the dark reactions
A
fructose
B
sucrose
C
ribose
D
glucose
Explanation: 

Detailed explanation-1: -Answer and Explanation: Glucose, C6H12O6, is produced during the dark reactions of photosynthesis, also known as the Calvin cycle. Photosynthesis starts with the light reactions. These reactions harvest the energy stored in sunlight and create chemical energy that can be used to power the dark reactions.

Detailed explanation-2: -In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose. It takes place in the stroma of the chloroplast.

Detailed explanation-3: -Plants make sugar by using energy from sunlight to transform carbon dioxide (CO2), a gas absorbed from the air, and water (H20) taken from the ground by roots into glucose (C6H12O6) and oxygen (O2). This process is called photosynthesis and occurs in the chloroplast of the plant cell.

Detailed explanation-4: -Dark phase is the light independent phase of photosynthesis in which ATP is utilised to synthesise glucose. Hence the dark phase is the only phase in which glucose is synthesised.

Detailed explanation-5: -ATP and NADH donate electrons to the 3-carbon molecules, which are converted into a 3-carbon sugar called glyceraldehyde-3-phosphate (G3P).
