Study Notes
Bioenergetics
- Carbohydrates, fats, and proteins have chemical structures that give them high potential energy due to the chemical bonds.
- Endergonic reactions require energy input, meaning they have a positive ΔG (change in free energy).
- Selenium is an essential component of the enzyme glutathione peroxidase.
- Bioenergetics is the study of energy changes that accompany biochemical reactions.
