Enzymes

Question 1

What are enzymes

Answer 1

Enzymes are proteins that speeds up the chemical reactions of cells

Question 2

Which one?
a. Enzymes causes reaction to happen
b. enzymes speed up reactions

Answer 2

b. Enzymes only speed up reactions that will already occur

Question 3

Are enzymes used up in reactions?

Answer 3

Enzymes are never used up in reactions. They can be used over and over again.

Question 4

How does enzymes work?

Answer 4

Reactions with enzymes depend on a physical fit between the enzyme and its specific substrate
Substrate molecules are the specific reactants of the reaction

Question 5

What is the equation for an enzyme?

Answer 5

Enzyme + substrate -> enzyme-substrate complex -> enzyme + new product

Question 6

True of false
Enzymes can either make or break down

Answer 6

TRUE

Question 7

Substrate molecules

Answer 7

The reactants in the reaction

Question 8

Products

Answer 8

New substances formed as a result of the reaction

Question 9

Active site

Answer 9

It is the fold or groove on the surface of the enzyme which the substrate molecule “fit” and bind to the enzyme

Question 10

Can enzymes work on multiple substrates?

Answer 10

No the shape of the enzyme is so specific that only one shaped substrate fit. This is why enzymes can only catalyse one specific reaction
