Question

2019-2020-Unit 4 Exam: Cellular Energy

1. A scientist set up 2 identical respiration chambers. In Respiration Chamber #1, the scientist put a mouse. In
Respiration Chamber #2, the scientist put a cricket. At the end of one hour, the scientist measured the amount
of Co, given off by the cricket and the mouse. A small amount of Co, had been given off by the mouse, but
very little co, had been given off by the cricket. Which claim below best explains why both the cricket and
mouse are carrying out cellular respiration?
a. Both the cricket and the mouse are organisms that contain mitochondria to conduct cellular respiration.
b. Both the cricket and the mouse are organisms that do NOT contain mitochondria to conduct cellular
respiration
c. Both the cricket and the mouse are organisms that contain chloroplasts to conduct cellular respiration.
d. Both the cricket and the mouse are organisms that contain a nucleus to conduct cellular respiration

Answer 1

The correct option is A) Both the cricket and the mouse are organisms that contain mitochondria to conduct cellular respiration.

Step-by-step explanation:

Mitochondria are known as the powerhouse of a cell. They are the sites where the process of cellular respiration occurs. Cellular respiration can be described as a process by which glucose and oxygen are converted into carbon dioxide and water along with the release of energy. Energy is released in the form of ATP during cellular respiration. ATP is used by almost every cell of the body to carry out its essential functions.
