Laboratory Procedure Manual

The increase in NADH concentration is directly proportional to the glucose concentration and can be measured spectrophotometrically at 340 nm. (1–3).

www.csun.eduGlycerol-3-Phosphate Shuttle • Functions in the skeletal muscle and brain. • NADH on the cytoplasmic side is oxidized to NAD+ with coupled reduction of DHAP to glycerol-3-phosphate. Enzyme: cytoplasmic glycerol-3-phosphate dehydrogenase. • The oxidation of glycerol 3-phosphate back to DHAP is
Glycolysis
www.csun.edu• Regulated only by excess glucose-6-phosphate. If G6P accumulates in the cell, there is feedback inhibition of hexokinase till the G6P is consumed. • Glucose-6-phosphate is required for other pathways including the pentose phosphate shunt and glycogen synthesis. So hexokinase step is not inhibited unless G-6-P accumulates.

REGULATION OF GLYCOLYSIS
aqu2018.weebly.compermits initiation of glycolysis even when blood glucose levels are relatively low. However, its Vmax is relatively low. • Hexokinase is inhibited by the product of its reaction, glucose-6-phosphate. This is a very important regulatory step, since it prevents the consumption of too much cellular ATP to form G6P when glucose is not limiting.
