Chapter 14, Problem 11RQ

Summary Introduction

To review:

1. The differences and common features of photosystem I (PS I) and photosystem II (PS II).

2. The two photosystems combine in the Z pathway.

3. The reason behind the generation of oxygen by the Z pathway while PS I and PS II are not able to do so.

Introduction:

Photosystems are the functional units of photosynthesis that are responsible to carry out absorption and transfer of light energy. Photosystems are of two types, photosystem I and photosystem II. ATP (adenosine triphosphate) is the energy currency of all cells that is produced by these photosystems.
