Question
Chapter 5, Problem 5MCQ
Summary Introduction
Introduction:
The Calvin cycle utilizes the energy produced by the light-dependent reaction into synthesizing carbohydrates from carbon dioxide. The NADPH (nicotinamide adenine dinucleotide phosphate) acts as a reducing agent that adds the high energy electrons to the carbon dioxide molecule to form polysaccharide (glucose).
