Question

The Calvin cycle functions to make organic molecules using CO2 as a source of carbon. What is the source of electrons that helps reduce CO2 to sugars and other organic molecules

Answer 1

Answer:

NADPH

Explanation:

Calvin cycle is also known as a light-independent reaction, this reaction takes place in the Stroma, and it does not require direct light. Instead of this, the Calvin cycle uses NADPH and ATP from the light-dependent cycle to reduce CO2 and produce a 3carbon sugar molecule (glyceraldehyde-3-phosphate), or G3P molecule, they join up to form a glucose molecule.

The light-dependent reaction absorbs the light energy and stores it temporarily in the form of NADPH and ATP. Then ATP is broken down for the release of energy and NADPH donates its electron to reduce CO2 into sugars and other organic molecules.
