Transport protiens are open on the outside and the molecule goes in the protien and it flips and then it enters the cell.
What else can I help you with?
What processes could result in the net movement of a substance into a cell if the substance is more concentrated in the cell than in the surroundings?
Active transport or facilitated diffusion could result in the net movement of a substance into a cell if it is more concentrated inside the cell than in the surroundings. In active transport, energy is required to move the substance against its concentration gradient. In facilitated diffusion, specific carrier proteins help the substance move into the cell down its concentration gradient.
How can a cell transport a substance from lower to higher concentration?
A cell can transport a substance from lower to higher concentration through active transport, which uses energy to move molecules against the concentration gradient. This process typically involves the use of specialized proteins in the cell membrane to pump the molecules against the concentration gradient.
Does exocytosis involve the use of transport proteins?
Yes, exocytosis involves the use of transport proteins to move molecules out of a cell.
Structure in a cell membrane that help particle to move in and out the cell during active transport are made of what?
The structures in a cell membrane that facilitate active transport are primarily composed of proteins, specifically membrane transport proteins or pumps. These proteins can include carrier proteins and channel proteins, which use energy, often in the form of ATP, to move particles against their concentration gradient. This process is essential for maintaining the cell's internal environment and enabling the transport of nutrients and ions.
How do proteins and polysaccharides that are too large to move onto a cell through diffusion or active transport move into the cell by?
Endocytosis.
Why must transport proteins be peripheral proteins?
Transport proteins must be peripheral proteins because they need to be able to move within the cell membrane to facilitate the transport of molecules across the membrane. Peripheral proteins are not embedded within the lipid bilayer of the membrane, allowing them to move more freely and interact with molecules on both sides of the membrane. This mobility is essential for transport proteins to effectively transport molecules across the cell membrane.
What is the function of channel proteins in cellular transport?
Channel proteins in cellular transport serve as passageways for specific molecules to move in and out of the cell, allowing for the regulation of substances entering and exiting the cell.
How does cell move molecule that is too large for transport proteins?
The cell membrane folds around the molecule.
What do the channel proteins in the cell membrane do?
Channel proteins, a type of transport proteins to the cells, move molecules from outside of the membrane to the inside
What requires the use of the energy and the help of transport proteins to move a molecule across a cell membrane?
Active transport
Which type of transport could not occur if the cell was inhibited in the production of protein?
Active transport would not be able to occur if the cell was inhibited in the production of proteins. Active transport relies on specific proteins, such as pumps and carriers, to move molecules against their concentration gradient. Without these proteins, the cell would not be able to perform active transport.
What is the definition of active transport?
active transport is an energy reqiuring process in which transport proteins bind with particles and move them through a cell membrane
