Added: Pentose phosphate pathway, lipid metabolism, gluconeogenesis, more advanced enzyme kinetics (for example, although Keq, Km and Vmax were old MCAT topics, new exam topics also include: Kd, Ka, kcat, Ki, IC50) Note: Many new MCAT Biochemistry topics were covered in the old MCAT in Biology and Organic Chemistry. The pentose phosphate pathway may be referred to as the pentose phosphate cycle, phosphogluconate pathway, hexose monophosphate cycle, or Warburg-Dickens-Horecker shunt.They all mean the same thing: the provision of NADPH and pentoses that can be used in other biochemical pathways.. NADPH is mainly found in tissues in which biosynthetic processes are … I was going over the Kaplan MCAT quick sheet and read that glucose-6-phosphate dehydrogenase (G6PD) is activated by NADP+ and inhibited by NADPH and Insulin. Just better. New MCAT Physics Two of the steps of the Pentose Phosphate Pathway are oxidated in nature.
