chapters 9-12 Flashcards
Carbon dioxide (CO2) is released during which of the following stages of cellular respiration?
oxidation of pyruvate to acetyl CoA and the citric acid cycle
In addition to ATP, what are the end products of glycolysis?
NADH and pyruvate
What is the correct sequence of stages in cellular respiration?
glycolysis, citric acid cycle, electron transport chain
The oxygen consumed during cellular respiration is involved in which process or event directly?
.accepting electrons at the end of the electron transport chain
Which of these equations describes aerobic cellular respiration?
glucose + oxygen → carbon dioxide + water + energy
What statement describes NAD+?
NAD+ is reduced to NADH during glycolysis, pyruvate oxidation, and the citric acid cycle
The molecule that functions as the reducing agent (electron donor) in a redox or oxidation-reduction reaction
loses electrons and loses potential energy
What is the term for metabolic pathways that release stored energy by breaking down complex molecules?
catabolic pathways
Which of the following normally occurs regardless of whether or not oxygen (O2) is present?
