Metabolism and Enzymes(2.5) Part 1 Pre – AP Biology Metabolism and Enzymes(2.5) Part 1

Metabolism

Kinetic Energy vs. Potential Energy

Potential Energy vs. Kinetic Energy in Chemical form

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

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

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

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)

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.

Enzyme Active site interacting with a substrate molecule.

Optimal Performance

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

Inhibitor molecules They slow down or stop the chemical reaction rate

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