Protein channels and carrier proteins are molecules located in the membrane that assist with facilitated diffusion. These proteins help facilitate the movement of specific molecules such as ions, sugars, and amino acids across the cell membrane.

What chloroplast structure are chlorophyll molecules found?
The chlorophyll pigment is located within the thylakoid membrane and the space between the thylakoid and the chloroplast membrane.
Is hormone reception a function of intergral membrane proteins?
Yes, hormone reception is often facilitated by integral membrane proteins called receptors. These receptors are typically located on the surface of the cell membrane and are responsible for binding specific hormones, triggering a series of cellular responses.
Where are chlorophyll molecules located within the chloroplasts?
They are in thylakoid membranes.They are stored inside
Where are MHC molecules located on a cell?
Major Histocompatibility Complex (MHC) molecules are located on the cell surface of a cell. They are expressed on the plasma membrane, presenting peptides to T cells for immune recognition and response.
State one function of the protein molecules that are located in cell membranes?
One function of protein molecules in cell membranes is to transport molecules in and out of the cell. These proteins act as channels or carriers that help regulate the movement of substances across the membrane.
What does the facilitated difussion depend on?
Facilitated diffusion depends on specific carrier proteins located in the cell membrane that help transport molecules across the membrane. These carrier proteins are selective and facilitate the movement of specific molecules based on their size, shape, and charge. Additionally, facilitated diffusion relies on the concentration gradient of the molecules to drive their movement across the membrane.
What are phosolipids?
Phoso - means contains phosorous and lipids- is a collective term that means fats of oils. So its a layer of a liquidy faty oil containing phosorous. Phosolipids are located in the cell membrane and help cell diffusion. They are involved in facilitated diffusion accross the cell membrane.
What is the function of porins?
Porins are proteins that are located in the outer membrane a bacteria. They function to form a water-filled pore through the membrane. The porin channel allows the diffusion of small hydrophilic (water-loving) molecules through to the periplasm.
Where are chlorophyll molecules located within plant cells?
Chlorophyll molecules are located in the chloroplasts of plant cells. They are bound to proteins in the thylakoid membranes, where they play a key role in capturing light energy for photosynthesis.
How does a carrier protein work?
A carrier protein works by binding to specific molecules on one side of a cell membrane, and then undergoing a conformational change to transport those molecules across the membrane to the other side. This process is selective and requires energy, typically in the form of ATP, to drive the transport against a concentration gradient.
Which vessel carries out diffusion or active transport with individual cells of the body?
The capillaries are the vessels that carry out diffusion with individual cells by allowing molecules to pass into and out of the bloodstream. Active transport with individual cells is carried out by specific transport proteins located in the cell membrane.
What chloroplast structure are chlorophyll molecules found?
The chlorophyll pigment is located within the thylakoid membrane and the space between the thylakoid and the chloroplast membrane.
What is Flippase?
Flippase is an enzyme that helps in the movement of lipids (such as phospholipids) between the two leaflets of a biological membrane. This process is important for maintaining proper membrane asymmetry.
Is hormone reception a function of intergral membrane proteins?
Yes, hormone reception is often facilitated by integral membrane proteins called receptors. These receptors are typically located on the surface of the cell membrane and are responsible for binding specific hormones, triggering a series of cellular responses.

Where are MHC molecules located on a cell?
Major Histocompatibility Complex (MHC) molecules are located on the cell surface of a cell. They are expressed on the plasma membrane, presenting peptides to T cells for immune recognition and response.
Where are transport proteins located?
Transport proteins are typically located in cell membranes, where they facilitate the movement of molecules across the membrane. These proteins can be found in both the plasma membrane of the cell and the membranes of intracellular organelles such as the mitochondria and endoplasmic reticulum.
