Cellular Respiration Begins with Glycolysis, and Therefore Oxidative Phosphorylation Within

question 45

Multiple Choice

Cellular respiration begins with glycolysis, and therefore oxidative phosphorylation within the cell is totally dependent on a constant source of glucose.

• A)This statement is true.
• B)This statement is incorrect because different carbohydrates may enter glycolysis at different steps in the pathway.
• C)This statement is incorrect because amino acids may furnish substrates for later steps in cellular respiration.
• D)This statement is incorrect because fats may also serve as a substrate for cellular respiration.
• E)This statement is incorrect because carbohydrates other than glucose, fatty acids, and amino acids can all supply substrates used in cellular respiration.
