Chapter 9, Problem 3TYU
Summary Introduction
Introduction: Photosynthesis is a process by which carbon dioxide and water are used to produce glucose molecules by using energy from sunlight. The process of conversion of light energy to the chemical energy occurs in the two phases of reactions, that is, the light-dependent reaction and carbon fixation reaction (dark reactions).
