Answer:
Option (A).
Explanation:
Facilitated diffusion may be defined as the process of movement of the particles from the region of higher concentration towards the region of lower concentration with the help of specific integral transmembrane protein.
Facilitated diffusion is a type of passive diffusion and solute particle down the concentration gradient. So this process doesn't require an ATP or any other energy source.
Thus, the mismatched pair is option (A).
Answer:
This is so simple. Read your lesson. If you cheat like this you'll never get through the rest of the course.
Explanation:
Solution:
According to the accepted current theory, known as the fluid mosaic model, the plasma membrane is composed of a double layer (bilayer) of lipids, oily substances found in all cells. The fluid mosaic model was first proposed by S.J. The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness.
Thus this is the required answer.
