NUMS MDCAT 2024 PAPER PART 2 1. During glycolysis, isomerization takes place in the formation of: Fructose 6 phosphate and 3 phosphoglycerate G3P and fructose 1-6 Bisphosphate Dihydroxyacetone phosphate and 2-phosphoglycerate PEP and pyruvate 2. Presence of PEP carboxylase in C4 plants enable them to avoid photorespiration due to: High yield of enzyme Absence of Rubisco Presence of enzyme in high concentration PEP carboxylase being strictly carboxylase 3.
