Question
Chapter 6, Problem 10SQ
Summary Introduction
Introduction:
The process of conversion of light energy to chemical energy occurs in two phases of reactions, that is light-dependent reaction and light-independent reaction. The two phases are included under photosynthesis in which absorption of light stimulates an electron molecule to a higher energy state, transforming the energy of sunlight to potential chemical energy.
