Document Summary
Stage 1: conversion of polymer into monomers through hydrolysis, ready to be absorbed. Stage 2: building up of monomers into a 2c molecule, as an intermediate, an acetyl group attached to. The 2c comes off as co2, in a series of redox reactions, nad gains the electrons, transformed into nadh. Oxygen is the final e- acceptor, producing water. Atp is then generated through a process of oxidative phosphorylation. Conversion of glucose into pyruvate, and the oxidation of nad+ into nadh. Could take place without oxygen, fermentation as it requires the regeneration of nad+, producing lactic acid in muscle and ethanol in yeast. Unlike aerobic energy production, produces a final organic compound. Invest 2 atp, to produce a 1,6, di phosphate fructose molecule. Caused by hexase kinase on the 6th carbon first first, phosphofructose kinase adding the po4 on the first carbon after. Ppfk acts as the pacemaker enzyme: cleave into 2 3c molecules.
