In what type of passive transport do protein channels assist molecules across the membrane?
In facilitated diffusion, protein channels assist molecules in crossing the cell membrane. This type of passive transport allows substances, such as ions and polar molecules, to move down their concentration gradient without using energy. The protein channels provide a pathway through the lipid bilayer, enabling the selective transport of specific molecules.
What type of transport does a small molecule enter a cell with help from a membrane protein additional energy is needed to complete this process?
Facilitated
What type of transport takes place when a protein allows?
When a protein facilitates the movement of substances across a cell membrane, it typically involves a process called transport. This can be either passive transport, where substances move along their concentration gradient without energy input (e.g., facilitated diffusion), or active transport, which requires energy to move substances against their concentration gradient. Transport proteins, such as channels or carriers, play a crucial role in ensuring that essential molecules enter or exit the cell efficiently.
Through what type of proteins does active transport occur?
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.
what two methods of transport require a transport protein?
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.

Facilitated
What is an transport?
Allows molecules to move but requires energy.
What type of transport takes place when a protein allows an ion to enter a cell but no additional energy is needed to make?
There are two types of transport that use channel proteins.The first type does not require energy to move the substance across the cell membrane.This is called facilitated diffusion. Energy is not required because the particles move along the concentration gradient, or the difference between the high concentration of particles outside the membrane and the low concentration of the particles inside.The second type of transport needs energy because it runs against the concentration gradient. This process is called active transport.

What is the difference between facilitated diffusion with the help of a carrier molecule with the help of a transport protein?
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
