Respiration in A2 Biology

Front

What is cellular respiration?

Back

The process of breaking down glucose to release energy in the form of ATP.

Front

What is the overall equation for aerobic respiration?

Back

C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP

Front

What molecule carries high-energy electrons to the electron transport chain during the Krebs cycle?

Back

NADH

Front

What type of respiration occurs in the absence of oxygen?

Back

Anaerobic respiration.

Front

What is produced during anaerobic respiration?

Back

Lactic acid or ethanol.

Front

How many ATP molecules are produced from one molecule of glucose during aerobic respiration?

Back

36 ATP molecules.

Front

What is the role of ATP in cellular respiration?

Back

ATP serves as the primary energy currency of the cell.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.

Front

What is the Krebs cycle?

Back

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

Front

What is fermentation?

Back

A metabolic process that converts sugar to acids, gases, or alcohol in the absence of oxygen.
