BIOC13H3 Lecture Notes - Lecture 2: Metabolic Pathway, Glycolysis, Catabolism
Document Summary
Lecture 2 topic 2c glycolysis (june 1. In this lecture, we will conclude our discussion with regards to glycolysis, beginning with an energetics summary of the glycolytic pathway and the 10 reactions that comprise of it. Energetics summary of glycolysis: there are really only two distinct pathways of glycolysis, glucose + 2nad+ 2nadh, where g " = -154kj/mol (this reaction represents the oxidation of nad+ by glucose, owing to glucose"s lower reduction potential: 2adp + 2pi. Efficiency of glycolysis: we can use the above information to calculate the efficiency of glycolysis, efficiency = Gconserved by anabolic part of the reaction. Semester: summer 2020: both of these effects apply in the context of facultative anaerobes, which can grow in either the presence or absence of oxygen, glycolysis alone yields 2atp/glucose, but oxidative phosphorylation yields 38atp/glucose. Under anaerobic conditions, the rate of glucose metabolism is faster, but the amount of atp produced is smaller.
