Question

If you had a sample organism and wanted to measure its rate of cellular respiration, which of the following methods would provide useful information? Study the equation for cellular respiration to have a clear sense of what is consumed and what is produced before answering the question.
A. By measuring the amount of glucose consumed
B. By measuring the amount of oxygen consumed
C. By measuring the amount of carbon dioxide produced

Answer 1

Answer:

The correct answer is all of them, options A. "By measuring the amount of glucose consumed", B. "By measuring the amount of oxygen consumed" and C. "By measuring the amount of carbon dioxide produced".

Explanation:

The simplest way to resume the equation of cellular respiration is as follows:  glucose + oxygen → carbon dioxide + water + energy. As it can be noted, they are different ways that the rate of cellular respiration could be measured. Valid ways include:

A. "By measuring the amount of glucose consumed". Because glucose is one of the reactants of the overall reaction.

B. "By measuring the amount of oxygen consumed". Because oxygen is one of the reactants of the overall reaction.

C. "By measuring the amount of carbon dioxide produced". Because carbon dioxide is one of the products of the overall reaction.
