2C Enzymes

Question 1

What does enzymes play a role in?

Answer 1

Metabolism

Question 2

What’s the function of enzymes

Answer 2

to speed up the useful chemical reactions in the body

Question 3

What does each enzyme have

Answer 3

An active site with a unique shape that fits into the substance involved in a specific reaction

Question 4

What’s the name of the substance that an enzyme acts on

Answer 4

Substrate

Question 5

What’s the lock and key model

Answer 5

That enzymes will only bund in to one specific substrate so if the substrate doesn’t fit the active site the reaction won’t be catalyse

Question 6

What is the activity of enzymes affected by

Answer 6

Ph and temperature

Question 7

How does temperature affect enzyme activity

Answer 7

Higher=faster rate but if too hot bonds holding enzyme tog will break substrate won’t fit anymore and it’ll be denatured

Question 8

How the ph affect enzyme activity

Answer 8

If too high or too low it interferes with bonds and denatures
Optimum ph is the best ph that work at many is 7ph

Question 9

What’s an example of an enzyme at what’s ph does it work at

Answer 9

Pepsin break down protein in stomach and works at ph2

Question 10

What are enzymes made of

Answer 10

Large proteins

Question 11

What do you enzymes act as

Answer 11

Biological catalysts
