Question

Gluconeogenesis is
A)Formation of glycogen
B)Formation of ammonia from glucose
C)Formation of glucose from non carbohydrate source
D)Breakdown of glucose.

Answer 1

Hint: Glucose metabolism usually includes multiple processes which includes glycolysis, gluconeogenesis, glycogenolysis, and glycogenesis. Glycolysis in the liver is a method that involves various enzymes that promote glucose catabolism in cells.

Complete answer:
Glucose is the innermost thing in the energy consumption. Carbohydrates, lipids, and proteins all eventually break down into glucose, then they serve as the most important metabolic fuel of mammals and the universal fuel of the fetus. It serves as the important precursor for the synthesis of diverse carbohydrates like glycogen, ribose, and deoxyribose, galactose, glycolipids, glycoproteins, and proteoglycans.

ATP is the energy prevalence of the body and which is consumed in multiple ways consisting the active transport of molecules across cell membranes. The contraction of muscles and action of mechanical work artificial reactions that help to create hormones, the cell membranes, and other essential molecules including the nerve impulse conduction, cell division and growth, and other physiologic functions.
Gluconeogenesis is a metabolic pathway which results in the generation of glucose from some of the non-carbohydrate carbon substrates. It is an ever-present process which is present in plants, animals, fungi, bacteria, and other microorganisms. In vertebrates the process gluconeogenesis takes place mainly in the liver. In humans the substrates for gluconeogenesis might come from any non-carbohydrate sources that can be converted to pyruvate or the intermediates of glycolysis.

In humans the main gluconeogenic precursors include the lactate, glycerol which are usually a part of the triacylglycerol molecule and also alanine and glutamine. On the whole they are responsible for over 90% of the overall gluconeogenesis. Additional glucogenic amino acids and all citric acid cycle intermediates through the conversion to oxaloacetate can also function as substrates for gluconeogenesis. In general human consumption of gluconeogenic substrates in food will not result in increased gluconeogenesis.

Hence, the correct answer is option (C)

Note: The greater part of the enzymes which are responsible for gluconeogenesis are seen in the cytosol. The exceptions cases include the mitochondrial pyruvate carboxylase and in the case of animals it is phosphoenolpyruvate carboxykinase.
