Yes insulin is the hormone which check the over production of glucose
The precursors for gluconeogenesis include lactate, glycerol, and glucogenic amino acids. These substrates can be converted into pyruvate, which then enters the gluconeogenesis pathway to produce glucose.
The starting material for gluconeogenesis is usually pyruvate, which can be converted into glucose through a series of enzymatic reactions. Other precursors such as lactate, amino acids, and glycerol can also be used to generate glucose through gluconeogenesis.
During gluconeogenesis in the postabsorptive state, amino acids and lactate are converted to glucose. Amino acids are primarily derived from muscle protein breakdown and can be used as substrates for gluconeogenesis to maintain blood glucose levels. Lactate is another important precursor for glucose production via gluconeogenesis in the liver.
Cortisol is the hormone responsible for the increase in blood glucose between 7am and 11am. Cortisol helps regulate glucose metabolism by promoting gluconeogenesis, the process of producing glucose from non-carbohydrate sources in the liver, leading to an increase in blood glucose levels.
TRUE
Insulin and cortisol
"start gluconeogenesis and glycolysis in hepatocytes!"
Insulin promotes various metabolic processes, including glucose uptake by cells, glycogen synthesis in the liver and muscle, and fat storage. However, it does not promote gluconeogenesis, which is the process of producing glucose from non-carbohydrate sources, as insulin actually inhibits this pathway. Therefore, insulin does not support the increase of blood glucose levels through gluconeogenesis.
Insulin is an anabolic hormone as: 1) it promotes glycogen synthesis & inhibits glycogenolysis and gluconeogenesis in carbohydrates. 2) it promotes lipogenesis & inhibits lipolysis. 3) promotes protein synthesis & inhibits protein degradation
Glucagon is the hormone that stimulates gluconeogenesis in the liver by increasing the breakdown of glycogen into glucose, promoting the formation of new glucose molecules.
Gluconeogenesis is primarily activated in response to low blood glucose levels, often occurring during fasting or prolonged exercise. Hormones such as glucagon and cortisol stimulate this process, while insulin inhibits it. Additionally, certain physiological conditions like stress and starvation further promote gluconeogenesis to maintain blood glucose levels and provide energy for vital organs.

The precursors for gluconeogenesis include lactate, glycerol, and glucogenic amino acids. These substrates can be converted into pyruvate, which then enters the gluconeogenesis pathway to produce glucose.
Cortisol
The anabolic role of gluconeogenesis is to break new glucose molecules from non-carbohydrate precursors.
The fructose-1-phosphate inhibits gluconeogenesis through the enzyme aldolase.
