The answer is <span>C. Fructose and glucose.

A disaccharide is a carbohydrate composed of two (prefix di-) monosaccharides bound by glycosidic bonds. The only monosaccharides among all choices are fructose and glucose. They together form disaccharide sucrose.
Other choices could not be correct because all mentioned molecules are not carbohydrates at all.</span>

What are monosaccharides, disaccharides, and polysaccharides and explain their functions?
Dmitrij [34]
Monosaccharide, disaccharides, and polysaccharides are the three major categories of molecules in Carbohydrates.

Monosaccharides, known as simple sugar, is the simplest form of carbohydrates. Its basic molecular formula is CH2O. Monosaccharides are glucose, fructose, and galactose. Its primary function is to be the source of energy of living organisms. It is also the primary requirement for the formation of disaccharides and polysaccharides.

Disaccharides are formed when two monosaccharides are bonded together through a covalent bond. Common Dissaccharides are sucrose  (glucose+fructose) or table sugar, maltose (glucose+glucose), and lactose (glucose+galactose). Its primary function is to provide nutrition for monosaccharides. Sugar in food is mostly dissaccharides.

Polysaccharides are formed when another monosaccharides is bonded to the disaccharides. This bond is called glycosidic bond. Two major polysaccharides are starch and glycogen. Starch is made by plants while glycogen is made by animals. Polysaccharides' major function is to immediately release energy from its storage. When glucose is consumed, some of them are stored and will only be released when the body needs it to satisfy the body's immediate need of energy.

prohojiy [21]
<span>A person who is ill with fever will experience an increased basal metabolic rate. The body’s metabolism contains all of the chemical and biological process needed for the conversion of food into energy and the use of it like digestion and excretion. So when we become sick, the metabolism speeds up to fight the illness.

Mama L [17]

Answer:

Transporte activo.

Explicación:

El transporte activo ocurre cuando una molécula se mueve de un área de menor concentración de sustancias a un área de mayor concentración. Los transportes activos utilizaron energía en forma de ATP para mover moléculas en contra del gradiente de concentración. Es lo opuesto al transporte pasivo en el que no se requiere energía para mover moléculas de una región a otra. La principal razón de que ocurra el transporte activo es que mueve moléculas en contra del flujo de difusión. En difusión, la molécula se mueve de un área de mayor concentración a un área de menor concentración.
