LIFE 102 Lecture Notes - Lecture 13: Anaerobic Respiration, Covalent Bond, Phosphorylation
Document Summary
Reasonable daily intake for an adult is 2,000 food calories. 1 calorie raises temperature of 1gm of water by 1 degree celsius. Uses oxygen and organic materials generated by photosynthesis. Partial degradation of sugars that occurs without oxygen. Consumes organic molecules and oxygen and yields atp. *some redox reactions do not transfer electrons but change the electron sharing in covalent bonds. *during cellular respiration, the fuel (e. g. glucose) is oxidized, and oxygen is reduced. Stepwise energy harvest via nad+ and the electron transport chain. In cellular respiration, glucose and other organic molecules are broken down in a series of steps. Electrons from organic compounds are usually first transferred to nad+ As an electron acceptor, nad+ functions as an oxidizing agent during cellular respiration. Each nadh (the reduced form of nad+) represents stored energy that is tapped to synthesize atp. Nadh passes electrons in a series of steps (instead of one explosive reaction) down the electron transport chain.
