--------------------------------- The 2 Types of Metabolism: --------------------------------- > 1 "Anabolism": Definition: A type of metabolism that uses or gains energy to build larger molecules. Examples: 1. Photosynthesis: Fixes CO2 by absorbing light (gaining energy) to produce glucose. <Converting CO2 (simple molecule) into sugar (complex molecule). 2. Polymerization: Building polymers from monomers. - Protein synthesis - DNA replication - synthesize glycogen or starch from glucose 3. Phosphorylation or condensation: Adding a phosphate group into ADP to produce ATP.
> 2 "Catabolism": Definition: A type of metabolism that breaks down bigger molecules into smaller units to release energy. Examples: 1. Cellular Respiration: Breaks down glucose to release energy. <This energy can be used in the cell to phosphorylate ADP into ATP> <Converts C6H12O6 (glucose) into CO2> 2. ATP Hydrolysis: Breaking down the bond between the 2nd and 3rd phosphate groups to release energy used for other cell activities/functions. 3. Digestion: Breaking down large molecules into smaller ones. - Proteins -> Amino acids - Carbohydrates -> Simple sugars
