Study Notes
Catabolic Reactions
- The key function of catabolic reactions is to release energy by breaking down complex molecules into simpler ones.
Energy Capture
- 40% of the energy released in catabolism is captured in the form of ATP.
Cellular Metabolism
- The sum total of the chemical activities of all cells is known as metabolism.
Nutrient Breakdown
- Carbohydrates, fats, and proteins are typically broken down first to meet energy needs.
Stages of Catabolism
- Stage I of catabolism involves the hydrolysis of macromolecules into their respective monomers.
- The primary aim of stage II of catabolism is to convert monomers into acetyl-CoA.
- The complete oxidation of acetyl-CoA to CO2 occurs in stage III of catabolism.
Biochemistry
- The branch of biochemistry that focuses on how cells transform energy, often by producing, storing, or consuming ATP, is known as bioenergetics.
Anabolism
- The primary function of anabolism in living organisms is to synthesize complex molecules from simpler ones, requiring a net input of energy.
Thermodynamics
- The second law of thermodynamics states that the entropy of the universe increases in all natural processes.
- The thermodynamic quantity that describes the amount of energy capable of doing work during a reaction at constant temperature and pressure is Gibbs free energy.
Catabolic Pathways
- The primary function of catabolic pathways is to release energy by breaking down complex molecules into simpler ones.
Energy Release
- Exergonic reactions release energy.
Bioenergetics
- The main focus of bioenergetics is how cells transform energy, often by producing, storing, or consuming ATP.
Reaction Types
- The production of stronger bonds allows the release of usable energy, which best describes exergonic reactions.
