Q

Transition state

A

Highest energy point from start to end (very unstable)

17
Q

Free E of activation

A

Determines how quickly reaction will go

18
Q

Standard free energy change

A

Net change

19
Q

What happens when reaction is catalyzed?

A

Transition state has a much lower energy, becomes more stable with the enzyme, and has a much lower activation energy

20
Q

Actions that can occur by enzymes

A

Can break apart, build, add, or rearrange molecules

21
Q
