Chapter 18, Problem 29CQ

(a)

Summary Introduction

To sketch: The oxygen consumption curve when amytal is added at time t=1 in a well-buffered suspension of mitochondria containing an excess of ADP and Pi.

Concept introduction: The oxygen consumption curve shows the consumption of oxygen by the electron transport chain and the consequence effect in production of ATP using ADP and Pi. Amytal is an irreversible inhibitor of electron transport chain.

(b)

Summary Introduction

To sketch: The oxygen consumption curve when amytal is added at time t=1 and succinate at time=2 in a well-buffered suspension of mitochondria containing an excess of ADP and Pi.

Concept introduction: The oxygen consumption curve shows the consumption of oxygen by the electron transport chain and the consequence effect in production of ATP using ADP and Pi. Amytal is an irreversible inhibitor of electron transport chain.
