Innermost compartment of a mitochondrion

the process that releases energy by breaking down food molecules in the presence of oxygen

the first step of cellular respiration, during which glucose is broken down into two molecules of pyruvic acid (pyruvate)

Glycolysis occurs in the _____ of the cell.

Glycolysis requires

Glycolysis produces

the electron carrier that accepts electrons during glycolysis

during glycolysis, ____ ATP are gained (net)

the second step of cellular respiration during which pyruvic acid (pyruvate) is further broken down, producing carbon dioxide

The Krebs (Citric Acid) Cycle occurs in the _____ of eukaryotic cells.

The Krebs Cycle requires

The Krebs Cycle produces

during the Krebs Cycle, ____ ATP are produced

the third step of cellular respiration, during which NADH and FADH₂ electron carriers are used to produce most of the ATP from glucose; produces water as a waste

The Electron Transport Chain (ETC) occurs in the _____ of eukaryotic cells.

The Electron Transport Chain (ETC) requires

The Electron Transport Chain (ETC) produces

The ETC uses _____ as the final electron acceptor, making water as a waste product

during the Electron Transport Chain, up to ____ ATP are produced

Up to ____ total ATP can be produced during cellular respiration from one molecule of glucose

What is the balanced chemical equation for Cellular Respiration?

When comparing cellular respiration and photosynthesis, these two processes are best described as

Cellular Respiration _____ energy in glucose by ______ chemical bonds

Photosynthesis _____ energy in glucose by ______ chemical bonds

"Without air"

process that releases some energy from partially broken down glucose without oxygen

Process used by cells that forms either lactic acid (lactate) or ethyl alcohol (ethanol) when no oxygen is present

select the organisms that carry out lactic acid fermentation

Your _______ can convert lactic acid back into pyruvate, but it needs oxygen to do so.

select the organism that carries out alcoholic fermentation

Both ethanol and _____ are produced during alcoholic fermentation.
