They are [1, 2] The major substrates are the glucogenic amino acids (), lactate, glycerol, and propionate.Liver and kidney are the major gluconeogenic tissues; the kidney may contribute up to 40% of total glucose synthesis in the fasting state and more in starvation. What step/s have to PPT Gluconeogenesis is much like glycolysis only the process occurs in reverse. In vertebrates, gluconeogenesis takes place mainly in the liver and, to a lesser extent, in the cortex of the kidneys. Gluconeogenesis is the reverse of glycolysis, with an extra step, which means it is a process that requires energy to be put into the reaction in order for it to occur. ...
