Transmembrane proteins are in a (fixed/unfixed) location in
What is mostly unfixed in the plasma membrane?
The two types of cell-surface markers
What is glycoproteins and glycolipids?
The phospholipid bilayer is made of
What is glycerol, 2 fatty acids, and phosphate?
The concentration gradient is
What is difference in concentration?
The three types of transport
What is active transport, passive transport, bulk transport?
Anchoring molecules attach
What is membrane protein to the membrane surface?
The function of cell surface markers
What is cell recognition of "self" and "nonself" cells by the immune system?
The four components of the cellular membrane
What is phospholipid bilayer, transmembrane proteins, interior protein network, cell-surface markers?
Phagocytosis is defined as
What is the movement of particulate matter into the cell?
What is the movement of molecules from high concentration to low concentration?
Transmembrane proteins include (list at least 4/6)
What are transporters, enzymes, receptors, identity markers, adhesion proteins, cytoskeleton attachment?
This component of cell-surface markers works by creating a protein/carbohydrate chain shape characteristic of individual.
What are glycoproteins?
This model, backed by electron microscopy, includes the nature of the membrane and the composition of proteins floating in the bilayer.
What is the fluid mosaic model? (fluid nature of membrane, mosaic composition of proteins)
Tonicity is defined as
What is the concentration of a solution as compared to another solution? (ex. hypotonic, hypertonic)
This process is the movement of substances out of the cell and requires energy
What is exocytosis?
This is a membrane-spanning region made up of hydrophobic amino acids arranged in α helices.
What is a transmembrane domain?
A, B, O blood group markers are examples of what
What are glycolipids?
This component of the interior protein network determines the shape of the cell
What are spectrins?
Osmosis is defined as
What is the net diffusion of water across a membrane toward a higher solute concentration?
These molecules bind to ions and other solutes and transport them via diffusion
What are carrier proteins?
Membrane protein functions (list at least 4/7)
What is
1. Transporters 2. Enzymes 3. Cell-surface receptors 4. Cell-surface identity markers 5. Cell-to-cell adhesion proteins 6. Attachments to the cytoskeleton 7. Affect membrane structure
?
This structure of the cell is what adds chains of sugar molecules to membrane proteins and lipids to create glycoproteins and glycolipids.
What is the endoplasmic reticulum?
These proteins are selective for one type of molecule and are responsible for the reason the cell membrane is said to be selectively permeable
What are channel proteins and carrier proteins?
The sodium-potassium pump is defined as
What is a pump that moves Na+ out of the cell and K+ into the cell against their concentration gradients using ATP?
(3 Na+ leave the cell, 2 K+ enter it)
The three major types of endocytosis
What are phagocytosis, pinocytosis, and receptor-mediated endocytosis?
