2. Metabolism

3. Kinetic Energy vs. Potential Energy

4. Potential Energy vs. Kinetic Energy in Chemical form

5. Potential Energy vs. Kinetic Energy as it happens in the environment

6. Thermodynamics and Material recycling Red = Energy flow Blue = chemical element flow

7. The making and using of ATP is a constant recycling process
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
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)

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

11. Enzyme Active site interacting with a substrate molecule.

12. Optimal Performance

13. Denaturation of a enzyme What bonds do you think broke allowing this to happen?

14. Inhibitor molecules They slow down or stop the chemical reaction rate

15. Feedback Inhibition See a product molecule going back and inhibiting the enzymes ability to work?
