Question

Hexose sugar is
A. Mannose
B. Galactose
C. Both A and B
D. Cellulose

Answer 1

Hint: Sugar or sugar alcohols are organic compounds which are derived from the sweet tasting soluble carbohydrates and contain one –OH functional group. It is also contained in energy form like ATP in the body mechanism of human beings.

Complete answer:
> Option A:
Cells make energy by separating macromolecules. Cellular respiration is the biochemical procedure that changes “food energy” into chemical energy as ATP. The first step of this confidently absorbed and complicated technique is glycolysis.

> Option B:
Glycolysis supports two primary intracellular functions: yield ATP and in-between metabolites to serve different paths. The glycolytic pathways changes one hexose, into two triose molecules

> Option C:
Glucose is a hexose sugar, which implies that it is monosaccharide with 6 carbon particles and 6 oxygen molecules. The main carbon includes an aldehyde collecting, and the other 5 carbons have 1 hydroxyl group each. In glycolysis, glucose is parted at last into pyruvate and energy, a sum of 2 ATP, is inferred instantaneously. The hydroxyl group takes into thought phosphorylation. The particular type of glucose used in glycolysis is glucose 6-phosphate.

> Option D:
Sugar gives a sweet taste and contributes fewer calories than other sugars. Sugar alcohol comes under the class polyols as they contain many hydroxyl groups. Erythritol, Xylitol, mannitol, and sorbitol are common examples of sugar alcohols.

Hence, the correct answer is option (C).

Note: Glucokinase is a subtype of hexokinase found in people. Glucokinase has a lower attraction for glucose and is found exclusively in the pancreas and liver, however hexokinase is found in all cells.
