5.1 Enzymes

Question 1

Enzymes will usually perform

Answer 1

hydrolysis or dehydration

Question 2

enzyme

Answer 2

biological catalyst that is usually a protein

Question 3

point of a catalyst

Answer 3

increase the speed with which a reaction happens

Question 4

substrate

Answer 4

reactant which binds to enzyme

Question 5

active site

Answer 5

where substrate fits into enzyme

Question 6

properties of enzymes

Answer 6

reaction specific
not consumed in reaction
made of protein
affected by cellular conditions

Question 7

factors affecting enzyme function

Answer 7

enzyme concentration
substrate concentration
temperature
pH
activators
inhibitors

Question 8

collision theory

Answer 8

reactants have to collide (in right configuration with enough energy) for reaction to occur

Question 9

how does temp affect enzymes

Answer 9

Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction.

Question 10

how does pH affect enzymes

Answer 10

Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity.

Question 11

enzyme concentration

Answer 11

Enzyme concentration refers to the number of enzymes present in an area. Changing this concentration can change the rate of the reaction that the enzymes are facilitating

Question 12

substrate concentration

Answer 12

he amount of substrate present that can be turned into product

Question 13

turning enzymes on

Answer 13

activator
cofactors
coenzymes
