Enzymes

Question 1

how does pH affect enzyme activity?

Answer 1

h+ ions and oh- ions disrupt the ionic bonding and hydrogen bonds that hold the enzymes active site in place

Question 2

factors affecting enzyme activity

Answer 2

temp

pH

substrate conc

enzyme conc

Question 3

cofactors

Answer 3

non protein substance

inorganic molecules

they help the enzyme and substrate bind together

Question 4

coenzymes

Answer 4

organic molecules

Question 5

prosthetic groups

Answer 5

a cofactor tightly bound to the enzyme

Question 6

inhibition

Answer 6

competitive

non competitive

end product

Question 7

competitive inhibition

Answer 7

molecules have a similar shape to the substrate and can enter the active site of the enzyme

this prevents/blocks the substrate from binding tocit

Question 8

non competitive inhibition

Answer 8

molecules bind to an allosteric site on the enzyme altering the active site so substrate molecules can no longer bind to it

Question 9

end product inhibition

Answer 9

the final product inhibits an enzyme that acts earlier on in the pathway
