Question

Match the transport process to its description. A. simple diffusion B. facilitated diffusion C. both D. neither confirm(s) to the properties of specificity, competition, and saturation

Answer 1

Simple diffusion do not show the property of specificity, competition, and saturation.

Facilitated diffusion shows properties of specificity, competition, and saturation.

Step-by-step explanation:

Diffusion or simple diffusion may be defined as the process of movement of particles along the concentration gradient and an energy independent process. Facilitated diffusion occurs with the help of carrier protein.

Specificity is the ability to transfer the specific molecules only. Simple diffusion is not specific in nature while facilitated diffusion can transfer specific molecules only. Competition refers to the ability of transporter to transport the closely related molecules but the substrate must compete with each other. The simple diffusion do not have any competition in their molecules whereas the molecules of the facilitated diffusion must compete with each other. Saturation means the transport rate depends on the substrate and number of molecules. This property is common in facilitated diffusion and not in simple diffusion.

Thus, the answer is Simple diffusion do not show the property of specificity, competition, and saturation.

Facilitated diffusion shows properties of specificity, competition, and saturation.
