Question

Synthesis of glucose from sources other than carbohydrates is called as-
A. Glycolysis
B. Glycogenesis
C. Gluconeogenesis
D. Glycogenolysis

Answer 1

Carbohydrates as we know are a very essential part of our balanced diet. Carbohydrates are the major biomolecules that are composed of carbon, hydrogen and oxygen. In the ratio of ${C_n}{H_{2n}}{O_n}$. They are the primary energy providing biomolecules and certain organisms. They also act as building materials for making cell walls and cell membranes.

Complete answer:
Option A Glycolysis- glycolysis is the metabolic pathway which converts glucose into pyruvic acid. It is the process of extracting energy for cellular metabolism. It has the energy releasing phase.
So, option A is incorrect.
Option B Glycogenesis- Glycogenesis is the process of converting sugar into glycogen. It's the process of making glycogen out of glucose molecules. Commonly it is used to provide energy during exercises, because the blood glucose concentrations are not sufficient.
Option B is incorrect.
Option C Gluconeogenesis- Gluconeogenesis is the process of producing glucose from non-carbohydrate substrates. The metabolic pathway is important because the brain depends on glucose for its activity.
Option C is correct.
Option D Glycogenolysis- it is the breakdown of the glycogen into glucose process. When additional energy is required, glycogenolysis occurs in muscle and liver cells.
Option D is incorrect.

Hence, Option C is the correct answer.

Additional information:
Carbohydrates are categorized according to how many sugar molecules they contain. Monosaccharides, disaccharides, and polysaccharides are the three types.
The monosaccharides are often called simple sugars which possess a free aldehyde. Only one sugar molecule is present in monosaccharides.
It is divided into trioses, tetroses, pentoses etc. Carbohydrates which possess sugars are- Glucose, glycose, ribose.

Note:
As we know, Glucose is the most common form of monosaccharide. Glucose used as an energy source and for the synthesis of starch, glycogen and cellulose is hexose. Ribose and deoxyribose are pentose sugars used in building RNA and DNA respectively. In aqueous solutions monosaccharides exist as rings. The monosaccharide glucose is significant in metabolism because it extracts chemical energy through glycolysis. The citric acid cycle, which used to supply fuel to living organisms. Other monosaccharides can convert to glucose in a live cell.
