Detailed explanation-1: -The major substrates of gluconeogenesis are lactate, glycerol, and glucogenic amino acids. Glycerol comes from adipose tissue. The breakdown of triacylglycerols in adipose tissue yields free fatty acids and glycerol molecules, the latter of which can circulate freely in the bloodstream until it reaches the liver[3].
Detailed explanation-2: -Thus, glycerol both inhibits the utilization of glucose for glycolysis and is effectively channelled into gluconeogenesis under glucose deprivation.
Detailed explanation-3: -Glycerol is a major substrate for glucose, glycogen, and nonessential amino acid synthesis in late-term chicken embryos.
Detailed explanation-4: -All are substrates for gluconeogenesis EXCEPT: A. glycerol.
