Muscle Metabolism

Question 1

glycolysis

Answer 1

glucose uses 2 ATP to make glyceraldehyde 3-phosphate which turns into pyruvic acid, making 4 ATP and 2 NADH

Question 2

acetyl-coa formation

Answer 2

pyruvic acid becomes acetyl-coa, making 2 NADH and 2 CO2

Question 3

kreb’s cycle

Answer 3

acetyl-coa goes through a series of steps, producing 6 NADH, 2 FADH2, 2 GTP that turn into ATP, and 4 CO2

Question 4

electron transport chain is a

Answer 4

series of oxidative-phosphorylation reactions

Question 5

oxidation

Answer 5

removal of electrons from a molecule that results in a decrease in energy

Question 6

reduction

Answer 6

addiction of electrons to a molecule that results in an increase in energy

Question 7

electron transport chain produces

Answer 7

32 to 24 ATP

Question 8

aerobic respiration produces

Answer 8

36 to 38 ATP total

Question 9

anaerobic respiration

Answer 9

glycolysis creates 2 ATP (net), pyruvic acid converts to lactic acid that goes into blood

Question 10

aerobic cellular respiration

Answer 10

amino acids from proteins, fatty acids from adipose, pyruvic acid from glycolysis, and oxygen from hemoglobin or myoglobin produces heat, 36 ATP, CO2, and H2O
