Answer from: shhells

The correct answer is:

a.glucose

Explanation:

Glucose is a simple sugar with the molecular formula C₆H₁₂O₆. Glucose travels in the blood of animals as blood sugar. It is produced through photosynthesis from water and carbon dioxide, using energy from sunlight.Carbohydrates are one of the four essential macromolecules of life. They are a polymer produced up of monomers described as monosaccharides. These building blocks are simple sugars, e.g., glucose

Answer from: lmimms02

A.Glucose is the carbohydrate monomer.

Further ExplanationCarbohydrates are large molecules made up of carbon, hydrogen, and oxygen. Carbohydrates may be simple or complex. Simple carbohydrates, also called simple sugars, are made up of single sugar molecules called monosaccharides or combinations of two monosaccharides called disaccharides. Examples of monosaccharides are glucose and fructose while lactose (combination of glucose and galactose) and sucrose (combination of glucose and fructose) are examples of disaccharides. Complex carbohydrates, on the other hand, are made up of long chains of repeating sugar units. This long chain of molecules is called a polymer and the repeating units are the monomers. Examples of carbohydrate polymers are cellulose, starch, and glycogen. Carbohydrates are the body’s source and storage of energy for the cells. Some carbohydrates like cellulose also give from to structures of living thing. Evaluating the Options

A.Glucose

TRUE Glucose is a monosaccharide. It may exist as a single sugar, be part of a disaccharide or be a monomer of a polysaccharide such as starch and glycogen which are made up of repeating units of glucose. Starch is found in plants such as rice, wheat, and potato.

B.Sucrose

FALSE Sucrose is a disaccharide made up of the monomers glucose and fructose.

C.Glucagon

FALSE Glucagon is not a carbohydrate. It is a hormone that is released from the pancreas to raise blood sugar levels.

D.Glycogen

FALSE Glycogen is a polysaccharide made up of monomers of glucose. Like starch in plants, glycogen stores energy for animal cells. It is the carbohydrate found in liver cells and broken down to glucose in the process called glycogenolysis.
