Potential Energy vs. Kinetic Energy in Chemical
form

Potential Energy vs. Kinetic Energyas it happens

Thermodynamics and Material recycling Red
Energy flowBlue chemical element flow
7
The making and using of ATP is a constant
recycling process. It needs free energy released
from our food to keep going
8
Free energy from our food molecules is use to
produce ATP. ATP is then used to power cellular
processes by providing phosphates (known as
phosphorylation)

Nature versus Enzymes in promoting chemical
reactions. Enzymes reduce the Energy of
Activation and thus speed up the rate of chemical
reactions.

molecule.

Denaturation of a enzymeWhat bonds do you think
broke allowing this to happen?
14
Inhibitor moleculesThey slow down or stop the
chemical reaction rate
15
Feedback InhibitionSee a product molecule going
back and inhibiting the enzymes ability to work?
