Question
Chapter 10, Problem 10.3CR
Summary Introduction
To describe: The steps where ATP and NADPH are used and the function of Rubisco in the Calvin cycle.
Concept introduction: The Calvin cycle is a series of biochemical reactions that occur inside the stroma of chloroplasts in which the atmospheric carbon dioxide is converted into a sugar molecule. In this process, ATP and NADPH are produced from the light reaction to provide chemical energy and reducing power, respectively.

Imagine a leaf in bright light but an atmosphere with no carbon dioxide. Would RuBP carboxylase be functioning? Would the NADP be in the reduced or oxidized form?
Describe the movement of the electrons of NADH through complex I to CoQ.
Briefly, explain why the transfer of electrons from NADH to the ETC results in the production of more ATP molecules than are produced as a result of the transfer of electrons from FADH2?
