enzymes structure + function

Question 1

what kinds of proteins are enzymes

Answer 1

globular proteins

Question 2

what kinds of proteins do enzymes have

Answer 2

mostly quaternary (some tertiary)

Question 3

define catabolic reactions

Answer 3

break down big molecules into small molecules

Question 4

define anabolic reactions

Answer 4

combine smaller molecules into larger molecules

Question 5

what is induced fit

Answer 5

enzyme changes shape in order to fit substrate

Question 6

define enzyme

Answer 6

biological enzymes used to speed up metabolic reactions

Question 7

what does an enzyme inhibitor do

Answer 7

interfere with functioning of the active site of an enzyme

Question 8

what do competitive inhibitors do

Answer 8

compete with substrate to occupy active site of enzyme (not permanent)

Question 9

what do non-competitive inhibitors do

Answer 9

alter the shape of the enzymes active site so enzyme cant function (permanent)

Question 10

define metabolic pathway

Answer 10

series of reactions in which each step is catalysed by an enzyme
