Question 3:Predict what will happen to the plasma membrane if there is no cholesterol. 相关知识点: 试题来源: 解析 Without cholesterol, the plasma membrane will become too fluid at normal bodytemperature and may rupture. Without cholesterol, the membrane will become toopermeable to dissolved ...
A plasma membrane is the part of a cell that encloses its interior components and allows certain parts of the outside environment...
Study the function of receptors. Examine the receptor definition and discover how plasma membrane receptors work with the immune system to keep the body healthy. Related to this Question There are 4 major macromolecules in the cells. What is the monomer of proteins, and what is the...
Plasma membrane (PM) biogenesis in polarized epithelial cells involves the generation of specialized PM domains, each facing a different environment and containing a distinct set of proteins. Many domain specific integral membrane proteins have complex type glycosylation and are cotranslationally inserted ...
in the plasma membrane enable the cell to receive signals from the environment.;import and export of molecules: channels and transporters in the membrane enable the import and export of small molecules selectively.;cell growth and motility : the flexibility of the membrane and its capacity for ...
A plasmodesma (the singular of plasmodesmata) is made of two components: the membrane and membrane spaces. The membrane part is an extension of the outer covering of the plant cell, the plasma membrane or the cell membrane. The membrane spaces are formed by the endoplasmic reticulum (a cell...
Proteins make up 50% of a plasma membrane’s mass. It occurs in two forms: peripheral (extrinsic) and integral (intrinsic). The membrane proteins for cell adhesion bind to the other proteins, such as those found in the extracellular matrix surrounding cells. Cell adhesion is hugely important...
The pharynx is part of what body system? A. respiratory B. muscular C. lymphatic D. circulatory In the intestine, ___ ensure(s) that most digested nutrients pass through the epithelial cells and not between them. (a) plasma membrane (b) desmosomes (c) tig...
a test result that is incorrect because the test indicated a condition or finding that does not exist. immunoglobulin any of several classes of structurally related proteins that function as antibodies or receptors and are found in plasma and other body fluids and in the membrane of certain cells...
The fluid mosaic model describes the structure of the plasma membrane and the properties that allow fluidity to the membrane. The plasma membrane is made primarily of lipids and proteins. The lipid bilayer is made up of phospholipids, glycolipids, and cholesterol. About half the mass of the...
