Both involve the binding of a specific substance to a particular kind of protein and a change in shape of the protein as the process (transport or chemical reaction) proceeds. After the process is completed, the protein is unchanged.
Proteins.
The vesicles because it contains and transports various substances such as protein
Carrier proteins transports specific molecules just as enzymes will only react to specific substrates. Molecules will only bind to their respective receptors. It can be thought of sort of like a puzzle piece, which will only fit into its correct place. Enzymes and substrates also function in this matter.
Proteins are the macromolecules primarily responsible for transporting substances in and out of cells. Specifically, membrane proteins, such as channels and transporters, facilitate the movement of ions, nutrients, and other molecules across the cell membrane. These proteins can operate passively, allowing substances to move along their concentration gradients, or actively, using energy to transport substances against their gradients.
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.
ribosomes make proteins and the endoplasmic reticulum transports materials through the cell
The substrate for peptidase are peptides, which are basically small proteins.
When a carrier protein binds with a substance it changes it shape during the transport. When an enzyme is present with a substrate the enzyme then like a carrier protein will change its shape.
Proteins
On the cellular level, it is the endoplasmic reticulum which processes and transports proteins.
proteins
A vesicle is a small, membrane-bound sac that stores and transports substances within a cell. Vesicles are involved in processes such as transporting proteins and lipids within the cell, as well as in communication between cells.
