Ch. 8 enzymes and energy

Question 1

Distinguish between the first and second law of Thermodynamics

Answer 1

Energy CANNOT be created or destroyed. It will be transferred and change forms.

Question 2

what is an endothermic or exothermic and positive and negative charge in Gibb’s free energy.

Answer 2

Exergonic- Exit
Endergonic- Enter
Gibb’s free energy- Energy lost or gained during a reaction

Question 3

What occurs during oxidation-reduction reaction

Answer 3

1 molecule loses an election

1 molecule gains an election

Question 4

What happens to a molecule when it is reduced or oxidized?

Answer 4

Uncharged/ charged molecule gains an extra electron

Question 5

Draw and label an enzyme

Answer 5

remember the active site, substrate, and after the chemical reaction

Question 6

Difference between synthesis and degradation

Answer 6

synthesis- 2 or more substrates into an active site

degradation- 1 reaction in an active site that ends with 2 or more products

Question 7

what happens after a reaction in an enzyme?

Answer 7

the enzyme goes back to its original shape and state

Question 8

inhibitor

Answer 8

bind to enzymes to block activity

Question 9

cofactors

Answer 9

needed for an enzyme to function

Question 10

Co enzymes

Answer 10

organic with similar functions as an enzyme. they bind with the enzyme to create an active
