Did NaCl require a transport protein for diffusion?
Some molecules are too large to pass through the cell membrane without transport proteins.
In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated
What part of the membrane helps chemical reac
They are too large to travel by passive transport. They must be broken down into amino acids and even those are too large and must use active transport. Those that are transported use protein channels and these include ions, amino acids, peptides, sugars, and other molecules that are mostly hydrophilic.
It's either a passive or active transport.
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
Two methods of transport that require a transport protein are facilitated diffusion and active transport. Facilitated diffusion involves the movement of molecules across a cell membrane through specific transport proteins, down their concentration gradient without the use of energy. Active transport, on the other hand, uses transport proteins to move substances against their concentration gradient, requiring energy in the form of ATP.
Carrier proteins can use active or passive transport depending on what type of carrier protein it is (meaning what the protein transports). The form of passive transport that they use is facilitated diffusion. An example of active transport is the Sodium Potassium pump. Active transport requires ATP. Facilitated diffusion is used to transport polar molecules and ions that cannot directly cross the cell membrane. Facilitated diffusion doesn't require energy.
a protein is too big to enter a cell on its own, therefore it requires carriers in order to do so. the carriers transport the protein in/out of the cell.
