Energy and Metabolism

Question 1

Cellular Respiration

Answer 1

biochemical reaction that releases energy from glucose, then stored in chemical bonds and released when bonds are broken in reactions.

Question 2

Adenosine Triphosphate (ATP)

Answer 2

gives up energy when split into ADP and a molecule of phosphate.

Question 3

Aerobic Cellular Respiration (3 main stages)

Answer 3

1. Glycolysis, occur in cytosol. Glucose molecules broken into 2 three-carbon molecules called Pyruvate.
2. Krebs cycle: occurs in the matrix of mitochondria. Pyruvate turned into Acetyl CoA
3. Electron transport chain occurs on the cristae, generates big no. of ATP molecules by moving electrons across cell membrane.

Question 4

Anaerobic Respiration

Answer 4

occurs when there is litter to no oxygen. some energy can still be released through fermentation
