Cellular Respiration: Processes, Components, and Fermentation Types

Cellular respiration

Process that involves the breakdown of glucose to produce ATP with the use of oxygen.

Three parts of cellular respiration

Glycolysis, Kreb's Citric Acid Cycle, electron transport chain.

Anaerobic

Process that takes place without oxygen.

Aerobic

Process that takes place with oxygen.

2 ATP

Number of ATP needed to start cellular respiration.

Mitochondria

Where Kreb's Citric Acid cycle and the electron transport chain of cellular respiration take place; most of the ATP is generated here.

Cytoplasm

Where fermentation takes place.

Oxygen

Final electron acceptor in the electron transport chain, needed to convert NADH and FADH to ATP.

Carbon dioxide and water

Waste products of cellular respiration.

Glucose and oxygen

Reactants of cellular respiration.

NADH

Gets converted to 3 ATP in the electron transport chain.

FADH

Gets converted to 2 ATP in the electron transport chain.

Lactic acid fermentation

Takes place in the cytoplasm; glucose is converted to 4 ATP without the use of oxygen.

Alcoholic fermentation

Takes place in the cytoplasm; glucose is converted to 4 ATP without the use of oxygen.

Yeast and bacterial cells

Cells that go through alcoholic fermentation.

Muscle cells, bacteria

Cells that go through alcoholic fermentation.

Lactic acid

Waste product of lactic acid fermentation.

Alcohol and carbon dioxide

Waste products of alcoholic fermentation.

36-38

Total number of ATP produced during cellular respiration per glucose molecule.
