Chapter 14, Problem 18P

Interpretation Introduction

(a) Interpretation:

The identification of the state that might predominate in each stage of the trace indicated with a letter on the given graph.

Concept introduction:

Mitochondria are the powerhouse of the cell. This organelle is involved in the synthesis of adenosine triphosphate (ATP; a molecule that stores energy) through the electron transport chain. An electron transport chain consists of a series of cytochrome complexes that transfer electron donors to electron acceptors coupled to the transfer of protons creating a proton motive force, driving the synthesis of ATP.

Interpretation Introduction

(b) Interpretation:

The determination of whether isolated mitochondria exhibit respiratory control, one determines the ratio of rates of oxygen uptake in two different states.

Concept introduction:

Mitochondria are powerhouse of the cell. This organelle is involved in the synthesis of adenosine triphosphate (ATP; a molecule that stores energy) through the electron transport chain. An electron transport chain consists of a series of cytochrome complexes that transfer electron donors to electron acceptors coupled to the transfer of protons creating a proton motive force, driving the synthesis of ATP.

Interpretation Introduction

(c) Interpretation:

The state that probably predominates in vivo in skeleton muscle fatigued from a long and strenuous workout.

Concept introduction:

Mitochondria are powerhouse of the cell. This organelle is involved in the synthesis of adenosine triphosphate (ATP; a molecule that stores energy) through the electron transport chain. An electron transport chain consists of a series of cytochrome complexes that transfer electron donors to electron acceptors coupled to the transfer of protons creating a proton motive force, driving the synthesis of ATP.

Interpretation Introduction

(d) Interpretation:

The state that probably predominates in resting skeleton muscle of a well-nourished animal.

Concept introduction:

Mitochondria are powerhouse of the cell. This organelle is involved in the synthesis of adenosine triphosphate (ATP; a molecule that stores energy) through the electron transport chain. An electron transport chain consists of a series of cytochrome complexes that transfer electron donors to electron acceptors coupled to the transfer of protons creating a proton motive force, driving the synthesis of ATP.

Interpretation Introduction

(e) Interpretation:

The state that probably predominates in heart muscle most of the time.

Concept introduction:
