Question
Chapter 7.3, Problem 1CC
Summary Introduction
To analyze:
The point at which electron has highest amount of energy from photosystem II to NADP+.
Introduction:
The electron moves in a zigzag manner through a series of energy changes that take place during photosynthesis. This is referred to as Z-scheme, which has been proposed by Hill and Bendall.
