Question 14

aka: cellular respiration

Answer 14

catabolism of carbs

Question 15

describe glycolysis

Answer 15

• in cytoplasm
• turns glucose into pyruvic acid
• makes 2 ATP
• in circumstances of low O2: turns pyruvic acid into lactic acid

Answer 16

• in mitochondria
• makes 30 ATP
• takes pyruvic acid from glycolysis to turn into CO2 & H2O
