4.3
Channel Proteins-Form tunnel across membrane to allow certain molecules to cross
Transport Proteins-Combine with substance to help move across membrane
Cell Recognition Proteins-Glycoproteins that can distinguish between our cells and other cells
Receptor Proteins-Has specific shape to bind with a signal molecule to bring about cellular response
Enzymatic Proteins-Participate in metabolic reactions, such as, degradative and synthetic reactions
Junction Proteins-Helps form junctions between cells and assist with cell-to-cell adhesion and communication
Which structure regulates the passage of molecules into and out of the cell?
The cell membrane separates the material outside the cell, extracellular, from the material inside the cell, intracellular. It maintains the integrity of a cell and controls passage of materials into and out of the cell.
Which structure regulates the passage or transport of certain molecules into and out of the cell quizlet?
The Plasma membrane uses its phospholipid bilayer and membrane proteins to regulate the passage of molecules into and out of the cell.
What regulates what moves things into and out of a cell?
The cell membrane controls what moves in and out of the cell. Cell membranes only allow some solutes (solids) to move across it. Movement across the membrane depends on size and type of the solute (solid).
What regulates the movement of molecules into and out of the cytoplasm?
The cell membrane regulates the movement of molecules in and out of the cell.
