Document Summary
Sum of all chemical reactions that occur in the body. Anabolic reactions (eg: making new proteins: synthesis of molecules. Bioenergetics: converting foodstuffs (fats, proteins, carbohydrates) into energy (units of kcal) Dna is kept in a closed and distinct compartment. Proteins are coded for here in the nucleus increase the productions of protein for the purpose of harnessing energy from the macronutrients. Dietary amino acids are sufficient to start the process. Anabolic steriods (the vial of medication is enough to stimulate the process faster than any other way we can) they go to the dna and ramp up the process of making more protein. Exergonic reactions reactions energy to: release energy (transfer to mechanical and/or chemical and thermal, exothermic. Oxidation: removing an electron (in order to oxidize something you have to reduce something else) Reduction: addition of an electron, oxidation and reduction are always coupled reactions, often involves the transfer of hydrogen atoms rather than free electrons.
