Document Summary

Step 1: glycolysis: an anaerobic process, occurs in the cytosol, requires 2 molecules of atp, each glucose molecule yields, 2 pyruvate molecules, net yield of 2 atp and 2 (nadh + h+) Step 2: conversion of pyruvate to acetyl coa. Step 2: fate of acetyl coa: enter the citric acid cycle (step 3, synthesis of fatty acids (when atp is abundant, ketone body formation. Fadh2 yields 1. 5 atp: total = 30-32 atp, range due to cytosolic nadh generated from glycolysis, extracting energy from fat, glycerol -> pyruvate of glucose (in liver, only 5% of fat"s weight, fas -> acetyl coa. Ferried into the mitochondrial by carnitine: beta oxidation removes 2 c at a time from the alpha end, end product: acetyl coa, nadh + h+, fadh2" Some aa enter tca cycle directly (energy or glucose: yields comparatively little atp, biosynthesis and storage: glucose, biosynthesis: gluconeogenesis, occurs in liver (90%) and kidneys, not reversal of glycolysis although share some common reactions.
