Energy Molecules

Energy cannot be created or destroyed, but it can change form.

Some molecules can store energy and transfer it to other molecules to do work

ATP/ADP

ATP - Adenosine Tri Phosphate

  • 3 phosphates

  • High energy form of the molecule

ADP - Adenosine Di Phosphate

  • 2 Phosphates

  • Low energy form of the molecule

Phosphorylation - process of adding a phosphate to a molecule

Carbohydrates

Carbohydrates are the main source of energy used to make ATP

  • Provide Short Term Energy

  • Monomers:  Monosaccharides/Single Sugars (glucose)

  • Polymers:  Starch, Glycogen

  • Starch/Glycogen are chains of glucose that can be built bigger to store sugar or broken apart to release sugar.

Lipids and Proteins as Energy

Lipids and Proteins can be used to make ATP, but need to be modified first
