Chapter 36, Problem 9STP

Summary Introduction

Introduction:

Internal respiration implies the exchange of gas between the bloodstream, cellular respiration, and tissue. From the surface of the tissue, gas partial pressure gradients, and blood perfusion, the gas exchanges.

Answer to Problem 9STP

Correct answer:

The correct answer is option (C) Gases are exchanged between the blood and the body’s cells.

Explanation of Solution

Explanation/justification for the correct answer:

Option (C) Gases are exchanged between the blood and the body’s cells. During internal respiration, gases are exchanged between the blood and the cells of the body. So, this is the correct option.

Explanation for incorrect answer:

Option (A) Carbon dioxide is used to derive energy from glucose. During photosynthesis, carbon dioxide is used to derive energy from glucose. So, this is an incorrect option.

Option (B) Gases are exchanged between the atmosphere and the blood. Gases are exchanged between the atmosphere and the blood during external respiration. So, this is an incorrect answer.

Option (D) Oxygen is used to derive energy from glucose. Oxygen is used to derive energy from glucose during cellular respiration. So, this is an incorrect answer.
