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...
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...
cell cmmunication: r eceptor proteins 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 ...
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...
What makes up the respiratory epithelium? List the four layers of the respiratory membrane. What is the function of synovial membranes? Name the three components that makeup the filtration membrane? (a) What are the major functions of the stomach? (b) Describe two of its secr...
1. What is a cell? Explain in detail. 2. Why are most cells small? 3. What do prokaryotic and eukaryotic cell have in common? 4. How do prokaryotic and eukaryotic cell differ? 5. How do things move across the plasma membrane? 6. What is cellular respirati ...
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 ...
You are looking at a cell that has on its membrane cholinergic receptors. What type of cell can it be, select ALL that apply: A. detrusor muscle (smooth muscle makes up most of the bladder wall) B. postganglionic parasympathetic neuron C. postganglion ...
What major blood protein do some lymphocytes produce and release into plasma? Which of the following is not considered a "formed element"? a. Erythrocytes. b. Plasma. c. Leukocyte. d. Platelets. The plasma membrane is mostly made up of?
