Cell mediated transports depends of sterospecificity, saturation, and competition
Carrier proteins are globular proteins which are specific in their actions, and thus regulate the entry and exit of particles into the cell. They help in the conduction of ionic substances and polar substances.
It exhibits a specificity for a particular type of molecule.

does not require energy.
usually happens with a concentration gradient (from a higher concentration to a lower concentration).

specificity, competition, and saturation
When we take food inside the body ,many mechanism starts.The process is known as food absorption.Most of the food is absorbed through Passive absorption without the expenditure of energy.But mineral and vitamin get absorbed through carrier mediated transport .In carrier mediated transport in the cell membrane in having limited no. of carriers which attaches itself to the vitamins and transport it to other side of the cell membrane i.e.blood
Active transport involves carrier proteins. Carrier proteins bind themselves to particles and transport them to highly concentrated areas within a cell.Facilitated diffusion and active transport require carrier proteins.
carrier proteins transport glucose into a muscle cell
== == Sugars and amino acids are taken up by a carrier-mediated transport systems into the small blood vessels in the intestinal walls then transported in the blood into the circulation.
Diffusion: process of movement of a substance from high concentration to low concentrationOsmosis: the passive of the solvent through a semi-permeable membrane to equalize concentrationsFacilitated Diffusion: also known as carrier mediated passive transport; the movement of substances into cells via carrier proteinsFiltration: process in which water and substances in the blood are pushed through the pores of the glomerulus. The resulting fluid is known as filtration
Carrier mediated transport is not a type of a active transport......because it is a type of facilitate diffusion.
It is not depenent on a concentration gradient.

Facilitated diffusion is a carrier-mediated form of transport across a membrane. The line-with-gaps model doesn't show the carrier proteins that are in the cell membrane. These proteins are what help facilitated diffusion occur.
Active transport Passive transport (diffusion and transport using protein channels) Receptor mediated transport
Active transport involves carrier proteins. Carrier proteins bind themselves to particles and transport them to highly concentrated areas within a cell.Facilitated diffusion and active transport require carrier proteins.
