Which of the following statements describes the results of this reaction? C6H12O6 + 6O2 -> 6CO2 + 6H2O + Energy

C6H12O6 is oxidized and O2 is reduced.

Why is glycolysis described as having an investment phase and a payoff phase?

It uses stored ATP and then forms a net increase in ATP.

Which of the following statements describes NAD+?

NAD+ is reduced to NADH during both glycolysis and the citric acid cycle.

Why are carbohydrates and fats considered high energy foods?

They have a lot of electrons associated with hydrogen.

The oxygen consumed during cellular respiration is involved directly in which process or event?

accepting electrons at the end of the electron transport chain

In the presence of oxygen, the three-carbon compound pyruvate can be catabolized in the citric acid cycle. First, however, the pyruvate 1) loses a carbon, which is given off as a molecule of CO2, 2) is oxidized to form a two-carbon compound called acetate, and 3) is bonded to coenzyme A. These three steps result in the formation of

acetyl CoA, NADH, H+, and CO2.

What is the term for metabolic pathways that release stored energy by breaking down complex molecules?

catabolic pathways

Where does glycolysis takes place?

cytosol

Which process in eukaryotic cells will proceed normally whether oxygen (O2) is present or absent?

glycolysis

Where is ATP synthase located in the mitochondrion?

inner membrane

The molecule that functions as the reducing agent (electron donor) in a redox or oxidation-reduction reaction

loses electrons and loses energy.

During cellular respiration, acetyl CoA accumulates in which location?

mitochondrial matrix

The ATP made during glycolysis is generated by

substrate-level phosphorylation.

Substrate-level phosphorylation accounts for approximately what percentage of the ATP formed during glycolysis?

100%.

In glycolysis, for each molecule of glucose oxidized to pyruvate

2 molecules of ATP are used and 4 molecules of ATP are produced.
