Question 1

what is the role of phosphoglycerate kinase in glycolysis?

Answer 1

production of ATP via substrate level phosphorylation

Question 2

what is the difference between aerobic and anaerobic glycolysis?

Answer 2

in aerobic glycolysis, NAD is regenerated, allowing the process to continue. pyruvate is also oxidised further in the citric acid cycle and via OXPHOS

Question 3

what are the 3 stages of beta oxidation?

Answer 3

activation of fatty acid
transport of fatty acyl CoA into the mitochondria
oxidation of fatty acyl CoA

Question 4

what enzymes are used for INTESTINAL digestion of proteins and amino acids?

Answer 4

chymotrypsin, trypsin, and carboxypetidase

Question 5

what are the two stages of amino acid degradation?

Answer 5

1-transfer of amino acid units to a-ketoglutarate aminotransferases
2-dehydrogenation to form ammonium ion glutarate dehydrogenases
