3A introducing enzymes

Question 1

enzymes

Answer 1

organic catalysts that speed up biochemical reactions by lowering the activation energy required to initiate a given reaction

Question 2

enzymes bind to

Answer 2

:molecules called substartes

Question 3

substrate:

Answer 3

undergoes chemical reaction n forms a product that leaves the enzyme - unchnaged

Question 4

enzymes are:

Answer 4

able to team up to work in a chain of reactions usually in a biochemical pathway

Question 5

how does this reaction occure:

Answer 5

-enzymes have active sites in tertiary structure
- when substrate binds to enzyme,forming enzyme substarte complex.
-undergoes conformational chnage causing small change to occure in substrate

Question 6

Lock and Key

Answer 6

that a substrate will fit perfectly into the active site of an enzyme (like a lock and key).

Question 7

Induced Fit

Answer 7

there is a slight adjustment upon binding to better fit the substrate and enzyme together.

Question 8

Activation energy

Answer 8

initial energy input needed in every chemical reaction. also the minimum amount of energy required to energise molecules to where they can undergo a chemical reaction
