Topic 8; Metabolism

Question 1

Metabolic Pathways

Answer 1

Chains and cycles of enzyme catalysed reactions

Question 2

Enzymes

Answer 2

Globular proteins which act as the catalysts of biochemical reactions

Question 3

Active site

Answer 3

Position on the enzyme which is occupied bny the substrate

Question 4

Enzyme inhibitors

Answer 4

Substances that reduce or prevent an enzymes activity

Question 5

Competitive Inhibition

Answer 5

the substrate and inhibitor compete for the active site of the enzyme

Question 6

Inhibitor molecule

Answer 6

binds to the active site physically preventing the substrate molecule from binding

Question 7

Non-competitive inhibitors

Answer 7

bind to enzyme in a place other than active site. (allosteric site) either bloks access to the active site or changes the shape of the active site
