Chapter 15, Problem 14P

Interpretation Introduction

Interpretation:

The mechanisms of the two types of photophosphorylation that explain all the given result should be described.

Concept introduction:

The two types of photophosphorylation reactions are given as:

1. When the chloroplast is illuminated in presence of ADP and Pi, ATP is produced as:
$ADP+Pi\stackrel{h\nu }{\to }ATP$
2. When, NADP+ was added to the ADP and Pi, illumination of chloroplast again yielded ATP as:
$NAD{P}^{+}+H_{2}O+ADP+Pi\stackrel{h\nu }{\to }NADPH+H^{+}+ATP+\frac{1}{2}{O}_2$
