Cellular Respiration and ATP Production Quiz

Energy Currency and Cellular Respiration

• ATP (Adenosine Triphosphate) is considered the universal energy currency in biological systems.

Electron Transport Chain

• In eukaryotic cells, the electron transport chain occurs in the mitochondria.

Oxidative Phosphorylation

• The enzyme responsible for catalyzing the conversion of ADP to ATP during oxidative phosphorylation is ATP synthase.

Carbon Dioxide Production

• Carbon dioxide is produced during the citric acid cycle (Krebs cycle) stage of cellular respiration.

Muscle Contraction

• The primary source of energy for muscle contraction during short bursts of intense activity is ATP and phosphocreatine (PCr).

Metabolic Pathways

• Glycolysis is a metabolic pathway that occurs in the cytoplasm and does not require oxygen.

ATP Production

• The net gain of ATP molecules produced from the complete oxidation of one molecule of glucose during cellular respiration is 36-38 ATP.

Krebs Cycle

• Coenzyme A (CoA) is regenerated at the end of the Krebs cycle to continue the cycle.

Anaerobic Conditions

• Under anaerobic conditions in animal cells, the final product of glycolysis is lactate.

Fatty Acid Breakdown

• Beta-oxidation is the process that involves the breakdown of fatty acids to produce acetyl-CoA molecules.
