Bio chapter 2 Quiz- Deck 4

Question 1

What are 4 factors that affect enzyme activity?

Answer 1

pH- each enzyme works best at a certain pH

Temperature- as temperature increases enzyme activity increases

Amount of substrate

Amount of enzyme

Question 2

As temperature continues to increase in a chemical reaction, the enzyme activity begins to decrease. This is called __[___

Answer 2

Denaturation (too high temperature changes the shape of an enzymes active site, and the substrate can no longer fit into the enzyme)

Question 3

Too high temperature changes the ______ of enzyme’s active site

Answer 3

Too high temperature changes the SHAPE of enzymes active site

(a high fever is an example of denaturation)

Question 4

As you add more substrate the speed of the reaction INCREASES or DECREASES?

Answer 4

As you add more substrate the speed of the reaction iNCREASES

Question 5

Reaction rate ________ as all the enzymes become active

Answer 5

LEVELS OFF

Question 6

As you add more enzyme the speed of the reaction iNCREASES or DECREASES?

Answer 6

As you add more enzyme the speed of the reaction INCREASES

Question 7

Reaction rate _______ when all the substrate is occupied by enzymes

Answer 7

Reaction rate LEVELS OFF when all the substrate is occupied by enzymes
