Question
Chapter 20, Problem 7P
Interpretation Introduction
Interpretation:
The reason why the carboxylation of rubisco is favored by high pH and high Mg2+ concentration in the stroma is to be determined.
Concept introduction:
Ribulose 1, 5-bisphosphate carboxylase/ oxygenase is abbreviated as Rubisco. This enzyme is involved in the first step of the carbon fixation process in which the carbon dioxide from the atmosphere is converted into energy rich molecules such as glucose by the plants and other photosynthetic organisms.

O The proton gradient is involved in the release of bound ATP from the synthase as a result of conformational change. O The conformational states interconvert as a result of proton flux through the synthase.
