Question

What type of cell transport uses carrier proteins?

Answer 1

Cell transport is the movement of materials or things across the cellular membrane. Cell transport has two types. They are active transport and passive transport. Passive transport doesn’t need energy to start but active transport needs some energy to start the process. Passive transport is proceeding through the diffusion, facilitated diffusion and osmosis. Passive transport occurs during the movement of substances from lower concentration region to lower concentration region.

Complete answer:
Carrier protein is changing their shape to allow or pass the other molecules through it. Active transport sends molecules through the cell membrane to the higher concentration side. So it needs external energy to move these molecules. This energy is consumed from the cellular energy in the formation of ATP. It secretes the endocytosis and exocytosis substances into the bloodstream. This Transportation allows the molecule to pass the cell membrane and it disrupts the equilibrium provided by the diffusion. In these process ions, large proteins, complex sugars and cells are transported.
Insoluble molecules will also enter in the process of active transport. This process performs against the concentration gradient. It occurs only at the semi permeable membrane. It is a highly selective process and has a rapid speed. This process is performing along all directions. Metabolic inhibitors are called as the influence of active transport. Active transport is also affected by the temperature.

Therefore, Active transport uses the carrier proteins.

Note:
Carrier protein is also called the cell membrane protein which is involved in facilitated diffusion and active transport of substances either out or in. It is used to form glucose molecules and transport them to the other molecules inside the cell. The substances are salt and amino acids. Carrier proteins are used in diffusion of sugars, amino acids and nucleosides. Cytochrome acts as the carrier protein in the electron transport chain for electrons.
