From each glucose molecule processed the cell gains 36 ATP. Glycolysis releases two by substrate level phosphorylation. However, glycolysis also releases hydrogen to NAD making it NADH which during the electron transport system creates 4 more ATP by oxidative phosphorylation. The krebs cycle (two revolutions) creates 2 by substrate level phosphorylation in the form of GTP. However, during the krebs, hydrogen is released to NAD and FAD making them NADH2 and FADH. These then travel to the electron transport chain and create 28 ATP through oxidative phosphorylation. NADH = 24 while FADH=4. Does this make sense? 4 through substrate level (2 in glycolysis and 2 in krebs) 32 through oxidative (4 from NADH produced through glycolysis, 24 through NADH in TCA/krebs cycle, and 2 from FADH2 produced in TCA/krebs cylce)

Hi there! I have two young kids (3 and 4),I work full time, and have been able to do it just fine. I was really scared to start school, but now I'm so glad that I have. I will be done with all of my pre req's after this semester and hopefully will start nursing school in the fall of this year. It is scary, but you can do it!
