How does cyanide prevent atp synthesis
WebAs the electrons flow through the series of oxidation reactions, much of the free energy of these reactions is trapped in the form of the proton motive force, which can then power the synthesis of ATP, a process called oxidative phosphorylation, as distinguished from substrate level phosphorylation. WebATP makes it easier to break apart glucose into two three-carbon molecules. ATP is used to reduce NAD+ to NADH. ATP makes it easier to break apart glucose into 2 3-carbon molecules Glycolysis literally means sugar producing. sugar splitting. energy producing. Embden-Meyerhof. sugar splitting
