Which of the following are absorbed by the mechanism of facilitated transport with the help of the carrier proteins
A. Glucose and amino acids
B. Fructose and alcohol
C. Fats and glucose
D. Fats and amino acids

Hint: Facilitated transport also known as facilitated diffusion is also defined as the form of transportation in which the material moves across the plasma membrane with the help of carrier proteins against the concentration gradient.

Complete answer:
The plasma membrane is made up of lipids and proteins due to which it is collectively known as the lipoproteins. According to the Fluid mosaic model, the membrane has the transmembrane proteins embedded in the layer. These proteins are the tunnel proteins and integral proteins. The integral proteins are also known as the intrinsic proteins. They make up seventy percent of the membrane. The intrinsic protein or the carrier protein helps in facilitating diffusion against the concentration gradient with the help of ATP. In facilitated diffusion, the membrane has no role to play. It is the diffusion that occurs with the help of carrier proteins. The carrier proteins form the complex with the molecule that is to be carried and then transports it across the membrane. Facilitated diffusion is used to transport the molecules of glucose and amino acids. Thus, based on the above information we can conclude that glucose and amino acids are absorbed by the mechanism of facilitated transport with the help of the carrier proteins.
Hence, the correct answer is option (A).

Note: The plasma membrane is the living membrane. It is the selectively permeable membrane in nature. This means that it allows all solvents and some selected solutes to pass through it. The plasma membrane is the outermost layer of the cell of an animal.
