Lactate Fermentation

PEP

Donates a phosphate to provide a direct return on the invested ATPs resulting in the end product of glycolysis, pyruvate: ________.

invests an ATP to produce a bi-phosphorylated hexose

phosphofructokinase

storage form of glucose found in muscle cells and abundantly in liver

glycogen

reduced product of GAPDH

NADH

donates a phosphate to provide a direct return on the invested ATPs resulting in the end product of glycolysis, pyruvate

Phosphoenolpyruvate (PEP)

invests an ATP to keep glucose in the cell

hexokinase

oxidizes a triose in glycolysis

GAPDH

activated substrate which donates a phosphate to ADP to produce one "profit" ATP from glycolysis

1,3 biphosphoglycerate

in the absence of sufficient oxygen, oxidizes NADH to regenerate NAD+ (a rate-limiting substrate), allowing glycolysis to proceed rapidly to meet emergency needs of muscle cells

lactate dehydrogenase (LDH)

travels to the liver to provide three carbons for gluconeogenesis
