Enzymes

Question 1

Catalyst

Answer 1

a substance that increases the rate of reaction but remains unchanged by the reaction

Question 2

Enzyme

Answer 2

A protein that acts as a biological catalyst

Question 3

Substrate

Answer 3

Molecule before reaction

Question 4

Product

Answer 4

Molecule(s) produced by reaction

Question 5

Catabolic

Answer 5

When molecules are broken down

Question 6

Anabolic

Answer 6

When molecules are joined together

Question 7

Effect on activation energy

Answer 7

Enzyme lower activation energy needed for reactions to occur at lower activation energy.

Question 8

Effect on temperature

Answer 8

Optimum temp is when they work best
Increase in temp will increase K.E so more chance of effective collisions increasing rate of reaction.
Too high temp will denature them
Too low temp very little collisions so slow

Question 9

Effect of pH

Answer 9

Work best at optimum pH

If pH changes can denature them and substrate no longer fit in active site
