Cell Respiration

What protein uses a proton gradient to make a lot of ATP?

ATP Synthase.

Where is ATP synthase located in the mitochondrion?

Inner membrane.

Glycolysis involves the ___________ of glucose.

Oxidation.

The primary role of oxygen in cellular respiration is to

act as an acceptor for electrons and hydrogen, forming water.

Where are the proteins of the electron transport chain located?

mitochondrial inner membrane.

Energy released by the electron transport chain is used to pump H+ into which location in eukaryotic cells?

mitochondrial inter membrane space

Carbon dioxide (CO2) is released during which of the following stages of cellular respiration? (you will want to look at figures 7.4, 7.6, 7.7, and 7-11 (note not all of these show CO2 release, some do).

oxidation of pyruvate to acetyl CoA and the citric acid cycle.

Which of the four stages of cellular respiration requires oxygen in elemental form O2 (i.e. not as a part of another molecule)?

oxidative phosphorylation.

The stored chemical energy that feeds into cellular respiration is in the form of:

reduced molecules like carbohydrates and fats which become oxidized in respiration.

How many carbon atoms are fed into the citric acid cycle by pyruvate?

two.
