Exam 17: Nutrition, Metabolism, and Body Temperature Regulation

Place the four general phases of glycolysis in the correct order from beginning to end: Input of ATP Sugar cleavage NADH production ATP and pyruvic acid production

Indicate whether each statement is true or false: 1. The second phase of aerobic respiration is the citric acid cycle. 2. The citric acid cycle begins with the production of citric acid from the combination of pyruvic acid and acetyl-CoA. 3. The results of the citric acid cycle are two ATP, six NADH, two FADH₂, and four carbon dioxide molecules.
