5. Enzymes

Question 1

Enzymes

Answer 1

These are proteins that function as biological catalysts

They lower the activation energy of a reaction

Question 2

Catalyst

Answer 2

A substance that speeds up a chemical reaction without changing the overall reaction

Question 3

Substrate

Answer 3

The molecules before they are made to react

Question 4

Active Site

Answer 4

This is what the substrate fits into when a reaction happens

Question 5

Product

Answer 5

The molecules that are made in the reaction

Question 6

Catabolic reaction

Answer 6

Molecules are broken down

Question 7

Anabolic reaction

Answer 7

Molecules are combined

Question 8

Temperature

Answer 8

At low temperatures, enzymes are slow.
They speed up as the temperature rises till they reach optimum temperature
After that point, that enzyme is denatured and the reaction slows down

Question 9

pH

Answer 9

Different enzymes work best at different pH’s

After they reach their optimum pH, the enzyme denatures and the reaction slows down

Question 10

Uses of Enzymes

Answer 10

Seeds germination: Turn insoluble food stores soluble

Biological Washing Powders: Enzymes are added to washing powders to help remove stains

Food industry: Isomerase converts glucose into fructose. Pectinase makes fruit juice less cloudy
