Detailed explanation-1: -Gluconeogenesis is the metabolic pathway in the body used to create glucose. It is an anabolic reaction, meaning it uses energy to build more complex molecules. This process is necessary to keep a constant supply of glucose sugar to be used as energy. Glycolysis is the reverse process of gluconeogenesis.

Detailed explanation-2: -An example of anabolism is gluconeogenesis. This is when the liver and kidneys produce glucose from noncarbohydrate sources. Catabolism is what happens when you digest food and the molecules break down in the body for use as energy.

Detailed explanation-3: -It is an anabolic process. When the level of glucose in the blood rises, glycogenesis occurs. The excess sugars are stored as glycogen. ATP molecule is utilized for glycogenesis and converted into ADP.

Detailed explanation-4: -Glycolysis, which literally means “breakdown of sugar, ‘’ is a catabolic process in which six-carbon sugars (hexoses) are oxidized and broken down into pyruvate molecules. The corresponding anabolic pathway by which glucose is synthesized is termed gluconeogenesis.

Detailed explanation-5: -The gluconeogenesis pathway is highly endergonic until it is coupled to the hydrolysis of ATP or GTP, effectively making the process exergonic. For example, the pathway leading from pyruvate to glucose-6-phosphate requires 4 molecules of ATP and 2 molecules of GTP to proceed spontaneously.
