amylase: intestine; carbohydrates chymotrypsin: intestine; proteins
lipase: intestine; proteins pepsin: stomach; proteins
14. Match the following metabolic reactions with their function: core
cycle: the conversion of lactic acid urge cycle: allows excretion of
nitrogen lipolysis: breakdown of triglycerides gluconeogenesis:
generation of glucose
15. Match the following steps in the aerobic respiration of glucose:
glycolysis: cytoplasm; oxygen-independent citric acid cycle:
mitochondrial matrix; requires oxygen oxidative phosphorylation:
inner mitochondrial membrane; required oxygen
16. Anaerobic metabolism of glucose: occurs in red blood cells
17. What are products of the citric acid cycle: 2 ATPS, NADH
and 2 C02
18. Select all of the following statements that are TRUE
concerning the aerobic metabolism of glucose: ATP synthase
requires a high concentration of hydrogen in the inter membrane
space
The initial steps of glycolysis require ATP
Glycolysis and citric acid cycle each produce 2 net ATP per
glucose
