    Study Notes

    Krebs Cycle Overview

    • The main function of the Krebs cycle is to generate energy for the cell by breaking down acetyl-CoA into carbon dioxide, releasing energy in the form of ATP, NADH, and FADH2.

    Glycolysis and Transition Reaction

    • When a single glucose completes glycolysis, 2 carbon dioxide molecules are produced in the transition reaction.

    Krebs Cycle Reactions

    • The end product of Reaction 1 in the Krebs cycle is citrate.

    History of the Krebs Cycle

    • The Krebs cycle was discovered by Hans Krebs.
    • Another name for the Krebs cycle is the citric acid cycle or tricarboxylic acid (TCA) cycle.
