Cellular respiration review

Front

What is the main job of the electron carriers in cellular respiration?

Back

Transport electrons and hydrogen atoms to the electron transport chain.

Front

In what part of the mitochondria does the electron transport chain occur?

Back

Inner mitochondrial membrane (folds of the mitochondria).

Front

The electron transport chain moves ____ along the chain and pumps ____ across the membrane.

Back

Electrons; Hydrogen.

Front

Which process produces the least amount of ATP in cells?

Back

Pyruvate Oxidation.

Front

During aerobic respiration, molecular oxygen (O2) is used for which of the following purposes?

Back

At the end of the electron transport chain to accept electrons and form H2O.

Front

What is glycolysis?

Back

The process of breaking down glucose into pyruvate, producing a small amount of ATP and NADH.

Front

What is the citric acid cycle?

Back

A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What role does ATP synthase play in cellular respiration?

Back

It synthesizes ATP from ADP and inorganic phosphate using the energy from the proton gradient.

Front

What is the final electron acceptor in the electron transport chain?

Back

Molecular oxygen (O2).

Front

What is lactic acid fermentation?

Back

An anaerobic process where glucose is converted into lactic acid and ATP when oxygen is scarce.
