What kind of membranes do human cells have?
The plasma membrane of eukaryotic cells are composed of a phospholipid bilayer.
What kind of membrane is cell membrane?
a plasma membrane
What controls the passage of materials into and out of the cell?
depend on the kind of cell...... plant: cell wall and cell membrane/plasma membrane animal: cell membrane/plasma membrane
What kind of cell is surrounded by a plasma membrane but does not have membrane bound organelles?
Prokaryote, or however you spell it.
What regulates passage of materials into and out of cells?
The cell membrane controls movement of materials in and out of the cell.
What kind of proteins span the plasma membrane creating a selectively permeable?
Transport protiens
What is the benefit of having some of the cellular organelles enclosed by a membrane similar to the plasma membrane?
"Analysis of a glandular secretion indicates that it contains some DNA, RNA, and membrane components such as phospholipids. What kind of secretion is this, and why?"
What cell is a cell membrane located in?
the "plasma" membrane encases the "exterior" portion of the cell ... human cell walls are comprised of a cellular or "plasma" membrane. the plasma membrane is also called the phoso-lipid bilayer
What kind of Bacteria moves by forming slime and using a wave like motion of their plasma membrane?
The answer us wavalactios bacterium
What kind of membranes do cells have?
all cells have a cell membrane to regulate what goes into and out of the cell I thought was the cell wall that did that and only the cell membrane was in a plant cell... but im not sure
What are the names of the peritoneal membranes?
The main importance of membrane proteins is its specific functions. The amount of proteins in membranes varies from 25 to 75% of the membrane constitution. The amount and types of membrane proteins are highly variable. To give a few examples: In plasma membrane , there are transmembrane proteins associated with lipids, either "single" or "multipass" proteins. Examples of this kind of proteins are the porins (present in different types of bacteria) and membrane receptors that react with antigens triggering signal transduction cascades to the cell interior in order to generate a cellular response (e.g., insulin growth factor recepetor or IGFR, fibroblast growth factor receptor or FGFR, nerve growth factor receptor or NGFR, plateled-derived growth factor receptor or PDGFR, etc.). On the other hand, we have the spectrin, a cytoskeletal protein noncovalently associated with the cytoplasmic side of the erythrocyte cell membrane. Also, we have the glycophorin A in erythrocyte plasma membrane, however with an uncertain function. In mitochondria, the are several kind of membrane-associated proteins, such as cytochromes, crucial for electron transport during "cell respiration". In bacteria, we found the bacteriorhodopsin, with light-absorbing activity.
What membrane membrane is composed entirely of connective tissue?
synovial
