Document Summary
The fundamentals of metabolism: metabolism = catabolism + anabolism. Catabolism = breaking down of food material into smaller particles. Uses stored nutrients, ingested foods, solar photons. Takes energy containing nutrients (carbohydrates, fats, proteins), makes atp, then produces energy-depleted products such as co2, h20, nh3. Anabolism = synthesis of macromolecules from small particles. Makes osmotic work, mechanical work, complex biomolecules, other cellular work. Takes precursor molecules (amino acids, sugars, fatty acids, nitrogenous bases) and uses atp to make macromolecules (proteins, polysaccharides, lipids, nucleic acids) Energy tissue level glucose, fatty acids, ketone bodies. Building blocks amino acids, isoprenoids, fatty acids, dna bases. Atp = usually refers to the terminal (high-energy) 2 bonds (the. At high concentrations atp acts as its own inhibitor: neurons use pcr since it is a fast source of energy, versatility. Versatile : can use carbohydrate, prtein, fat, etc. Body can easily convert proteins sugar fatty acid with exceptions of essential aa and fa.
