22
Q

What is Reduction?

A

Loading a molecule with electrons

23
Q

What is oxidation?

A

Removing electrons from a molecule

24
Q

What does reduction do with free energy?

A

It requires free energy (Delta G goes up)

25
Q

What does oxidation do with free energy?

A

It releases energy (Delta G goes down)

26
Q

A

YES

27
Q
