Question
Chapter 8.2, Problem 2SB
Summary Introduction
To review:
The formation of NADPH (nicotinamide adenine dinucleotide phosphate) in linear electron flow.
Introduction:
The process of photosynthesis includes two kinds of photosystems (I and II) that are involved in the formation of ATP (adenosine triphosphate) and NADPH in the light-dependent reaction. During photosynthesis, the light energy from the sun is converted into chemical energy.
