B3.4-5 Enzymes And Factors Affecting Then

Question 1

What are enzymes ?

Answer 1

Biological catalysts- speed up reactions without being used up themselves

Question 2

What are they involved in?

Answer 2

Controlling metabolism( the sun of all reactions in a cell or in the body)

Question 3

What are enzymes like actually not their definition?

Answer 3

They are proteins

Question 4

How do they work ?

Answer 4

At the enzyme the complimentary substrate attaches to the active site where the products are made

Question 5

What is the original idea?

Answer 5

Lick and key theory
Substrate had to fit perfectly into the active site

Question 6

How does temperature affect the function of enzymes ?

Answer 6

As the temp increases so does the rate of reaction due to higher Kentucky energy but if the temp is too high the enzymes denature meaning they loose their shape so the active site won’t work

Question 7

How do we know an enzyme has denatured ?

Answer 7

When it reaches the bottom of the graph but when the curve starts to dip it’s beginning to denature

Question 8

What is the optimum temperature ?

Answer 8

The highest temperature before denaturing happens

Question 9

How does the PH affect the rate of reaction

Answer 9

If it’s too high or too low it changes the shape of the enzyme so the active site stops working so it’s denatured

Question 10

What is optimal PH

Answer 10

Where the enzyme usually works which is usually around 7 but owns in the stomach are around 2 as the stomach is very acidic
