Cells need to regulate each substance so its import and export is controlled. If there would be one mechanism to import every substance, the concentration of any individual molecule couldn't be controlled.
The plasma membrane proteins have many functions. They pass on information through the membrane, they give the cell structural support and recognize different particles within the cell, and they are also transporters.
Growth and reproduction, movement, and transport of certain materials across the cell membrane
The outer compartment of the mitochondria contains a variety of enzymes involved in lipid metabolism, as well as proteins that help transport molecules into and out of the mitochondria. These enzymes and proteins play crucial roles in regulating the transport of molecules such as lipids, ions, and metabolites across the mitochondrial membrane.
Cells use a variety of transport mechanisms to deliver molecules within and outside the cell. This includes processes like endocytosis, exocytosis, diffusion, and active transport. These mechanisms ensure that essential molecules and signals are properly transported to maintain cell function.
Cell regulation is conducted by a variety of mechanisms, including signaling pathways, gene expression regulation, and protein modifications such as phosphorylation. These mechanisms help ensure that cells respond appropriately to different internal and external cues to maintain homeostasis and carry out specific functions.
Membrane proteins have a variety of functions. They relay signals between the cell's inside and outside environments. Transport proteins move the molecules across the membrane.

Carbohydrates are not found separately in the membranes, they are always attached to proteins. Their usual role is to act as receptors or antigens. Proteins do a variety of things, mainly conducting the numerous types of membrane transport mechanisms: facilitated diffusion, channel proteins, etc. They can also act as anchors for extra- and intracellular skeletons.
The phenomenon of multidrug resistance is correlated with the presence of a membrane protein, P-glycoprotein, which pumps a wide variety of drugs out of cells thus reducing their toxicity. This is similar to "flippase" but the mode of action is unknown. It requires energy as do all enzymes and is not a passive transport mechanism.
Membrane proteins have a variety of uses that include: * forming ion channels * shuttling molecules by active transport * providing structural interrity to the cell membrane * acting as receptors for specific ligands * acting as points of adhesion to aid in cell adhesion to other cells or to the substratum * as anchorage points for the cytoskeletal structure

Membrane bound enzymes are enzymes in a membrane that are responsible for the maintenance of cellular functions such as ion transport, secretion and uptake of a variety of substances, as well as cell to cell interactions. A membrane-bound organelle is an organelle surrounded by a plasma membrane.
