Chapter 22, Problem 17RE
Interpretation Introduction

Interpretation:

The comparison between the energy requirement of photosystem I and II is to be determined.

Concept introduction:

Photosystem I uses the light of high wavelength to reduce NADP+ to NADPH, while photosystem II uses the light of low wavelength for the oxidation of water to produce oxygen.

The energy (E) of the photon is given as:

E = hcλ

Here, h is Plank’s constant, c is the velocity of light, and λ is the wavelength.
