Biology Cell Respiration

Starting with one molecule of glucose, the energy-containing products of glycolysis are

2 NADH, 2 pyruvate, and 2 ATP

For each mole of glucose (C6H12O6) oxidized by cellular respiration, how many moles of CO2 are released in the citric acid cycle (see the accompanying figure)?

4

Which of the following is the most correct interpretation of the figure?

ATP is a molecule that acts as an intermediary to store energy for cellular work

Which of the listed statements describes the results of the following reaction? C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + Energy

C6H12O6 is oxidized and O2 is reduced

Anabolism

Metabolic pathways that construct molecules, requiring energy.

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

Which of the following is most similar in structure to ATP?

an RNA nucleotide

Which term most precisely describes the cellular process of breaking down large molecules into smaller ones?

catabolism (catabolic pathways)

anabolic pathways

consume energy to build up polymers from monomers

Why is ATP an important molecule in metabolism?

its terminal phosphate group contains a strong covalent bond that, when hydrolyzed, releases free energy

When a molecule of NAD+ (nicotinamide adenine dinucleotide) gains a hydrogen atom (not a proton), the molecule becomes

reduced
