What are the four types of proteins found in the cell membrane?
Actually, bilipid "heads" form the layers of the membrane, but there are carrier proteins that transport objects into and out of the cells. These carrier proteins use either active or passive transport to get objects across the membrane. Active transport uses energy, while passive transport doesn't need to use energy to get items across. Hope this helps!!!
Mitochondria are needed for the cell to transport glucose across the cell membrane into the blood what is the method that the cell uses to do this?
Mitochondria are not directly involved in transporting glucose across the cell membrane. Glucose transport into the cell is primarily facilitated by glucose transport proteins located on the cell membrane. These transport proteins utilize concentration gradients to move glucose into or out of the cell as needed.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
Does active transport get substances across a cell membrane?
Yes, active transport is a process that uses energy to move substances across a cell membrane against their concentration gradient. This enables the cell to accumulate certain molecules or ions inside the cell or remove them from the cell.
How does the cell membrane pass materials?
The cell membrane passes materials through a process called passive or active transport. Passive transport uses the natural movement of molecules from an area of high concentration to low concentration, while active transport uses energy to move molecules against their concentration gradient. Additionally, the cell membrane contains specific transport proteins that facilitate the movement of molecules in and out of the cell.

Are proteins found in the cell membrane?
There are many uses for proteins in a cell membrane but the most common ones are: 1. Facilitated diffusion- a protein acts almost like a channel to allow molecules that cannot fit across the phospholipid bilayer to diffuse into/out of the cell 2. Active transport- proteins are used to move particles across the membrane from low to high concentration, using energy. 3. As receptor molecules which take signals from things like hormones.
What is the sentence that uses the word cell membrane?
The cell membrane is selectively permeable.
What is a sentence that uses the words cell membrane?
The cell membrane is selectively permeable.
What are membrane proteins used for?
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

What uses a protein to move a molecule across a cell membrane without using energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What does the cell use proteins for?
A cell uses Proteins for repairing and building up muscles injuries.
Does Exocytosis use a channel or carrier protein?
Exocytosis uses carrier proteins to transport molecules out of the cell. These carrier proteins facilitate the fusion of transport vesicles with the cell membrane, enabling the release of molecules outside the cell.
