Question
Chapter 21, Problem 21P
Interpretation Introduction
To Explain:
The reason for dimerization occurrence and to identify the residues driving it using Active Model for photosystem II.
Introduction:
Photosystem II or PSII is a specialized protein complex. Here, light energy is used to force the electron transfer from water to plastoquinone. As a result of this, oxygen is produced and reduced plastoquinone is released to photosynthetic membrane.
