The correct answer is option (D) The active transport and the facilitated diffusion both involve the proteins present in the cell membrane.
Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane. In this case, the solute move from a region of higher concentration to lower concentration and it does not require energy.
Active transports takes place when the molecules move from a region of lower concentration to higher concentration via the membrane protein channels.
Both facilitated diffusion and active transport requires the proteins present in the cell membrane.
The gradual evolution for the family Equidae (horse family) has been well documented within the fossil record.
Living things require specific organic molecules in order to survive. The picture above represents some specific examples of foods that are mainly composed of one of these necessary organic molecules. The organic molecules found in these types of food are
B) proteins.
