Study Notes
- Metabolism involves catabolic reactions (breakdown of molecules) and anabolic reactions (building of molecules) in the body.
- Glucose from complex carbohydrates like starch is broken down in the digestive system, absorbed into the blood, and used for cellular respiration to produce ATP.
- Excess glucose can be stored as glycogen through an anabolic reaction in the liver and skeletal muscle.
- Triglycerides from fats can be broken down into glycerol and fatty acids for energy storage, with triglycerides providing significantly more ATP than glucose.
- Proteins are broken down into amino acids for protein synthesis, with excess proteins broken down into amino acids for energy in starvation mode.
- Glucose intermediates can be used to make glycerol, fatty acids, or even converted into certain amino acids in different tissues depending on the enzymes expressed.
