Question 1

substrate

Answer 1

the substance an enzyme reacts with

Question 2

complementary

Answer 2

the enzymes active site and substrate have shapes that allow them to fit together

Question 3

synthesis

Answer 3

build up of small molecules into larger ones

Question 4

product

Answer 4

the substance produced at the end of a reaction

Question 5

degradation

Answer 5

breakdown of large molecules into smaller ones

Question 6

active site

Answer 6

the area on an enzyme where the substrate binds and the chemical reaction occurs

Question 7

optimum

Answer 7

the temperature at which an enzyme is most active

Question 8

biological catalyst

Answer 8

speeds up a cellular reaction

Question 9

specific

Answer 9

each enzyme can fit together with one substrate only

Question 10

denatured

Answer 10

the shape of the active site has changed and the enzyme can no longer fit together with the substrate

Question 11

Answer 11

pasteurized milk and rennet
the rennet separates the curds from the whey

Question 12

whey

Answer 12

the watery part of milk that remains after the curds have formed

Question 13
