The plasma membrane is a semi-permeable membrane. This means that it is: A) permeable to small but not too large substances. B) only permeable to cholesterol. C) permeable to large charged molecules but not too small uncharged molecules. D) permeable to s ...
What is the projections of the plasma membrane of a mucosal epithelial cell? 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. postganglio...

For example, once you've got the idea of membrane proteins down, passive and active transport are easy to understand. Also, as you pointed out, there are membranes inside the cell too. Once you understand the plasma membrane around the cell, the interior membranes make sense too!

It is characterized by a rounding of the cell, a gain in cell vol- ume, mitochondrial swelling, dissolution of organelles, con- densation of chromatin around the nucleus, and irreparable damage to the plasma membrane both by external influences and by the release of intracellular lytic enzymes...
Therefore, SARS-CoV-2 Spike entering cells without TMPRSS2 may gain entry through cathepsin L on the plasma membrane surface. However, SARS-CoV-2 Spike is activated by cathepsin L in endosomes, resulting from TMPRSS2 protein helping viruses enter the plasma membrane. A viral genome has been ...

A cell is composed primarily of the elements hydrogen, carbon, oxygen and nitrogen. These molecules make up the organic molecules like carbohydrates, proteins, fats, and nucleic acid that compose the different parts of the cell. These different parts of the cell are the plasma membrane, nucleus...
