Document Summary

Lecture 9 - 9/04/18 - metabolism: understanding the basics. Is the biology of energy transformations and energy exchanges within and betweeen living things and their environments. Metablolic processes nare all the chemical reactions that occur in cells, tissues, organs and organ systems. Build up (anabolic) reactions absorb or require energy: endergonic/endothermic. It does this by mimicking the amino acids that would normally bind to this site: non competitive inhibition, has structure different than the substrate. Potential energy is gained as electron is pulled away from a proton. Covalent bonds: one or more pairs of electrons are shared by 2 atoms. Hydrogen bonds: formed between an electropositive atom hydrogen and electronegative atom such as oxygen or nitrogen. A photon strikes a molecule and its energy is changed from light energy into electrical energy. Boosts electrons to a higher, more unstable orbital - very reactive. Oxidation of chemical compouds (organic or inorganic) to obtain energy.
