Document Summary

Catabolism: rxns that breakdown nutrients (produces energy and some components) Catabolism examples: breaking lactose into glucose and glactose into smaller molecules, amino acids (ex. Histidine) degrading to produce reduced nitrogen (nh4+) and carbon molecules. **energy being produced is trapped in other molecules. Atp and electrons are trapped in a molecule called nadh + h+ (reduced nicotine adenine dinucleotide) * uses the energy (atp and nadh + h+) trapped in other molecules. * cells can take up molecules and use them in anabolic rxns without breaking them down first. ** human cells cannot male 8 essential amino acids (so they are absorbed from food and used directly in protein synthesis) ** majority of bacteria are capable of making amino acids therefore have more complicated anabolic rxns. All organisms can use to make atp. No chemolithotrophs or phototrophs use only this. Things to remember: cells are made of c,h,n,o,p and s, heterotrophs: get cellular carbon from environment (ex.
