while F-actin velocity across the entirety of the cell is governed by equation (2). The addition of F-actin turnover and anterior polymerization enabled the emergence of a new F-actin organization state, in which actin transport is largely unidirectional and rearward (Fig. 4a and Supplementary...

Channel proteins in cell membranes serve what function? Why is the tail of a phospholipid hydrophobic? Why is it important for cells to be able to use both active and passive transport to transport molecules across the cell membrane? How are lipids diffus...
“Extraordinarily fast transport of water in carbon nanotubes has generally been attributed to the smoothness of the nanotube walls and their hydrophobic, or water-hating surfaces,” said Narayana R. Aluru, a Willett Faculty Scholar and a professor of mechanical science and engineering at the U. o...
The aqueous environment of cells can be described based on its concentration of solute. There are three main types of solutions, hypertonic which has a greater concentration of solute compared to the cell, hypotonic which has a lesser concentration of solute, and isotonic where the amount of solu...
a. It diffuses across membranes much more easily than does oxygen. b. It is carried in blood as carbaminohemoglobin. c. It can be converted into bicarbonate ion. d. It is replaced on hemoglobin by o Which of the following increases oxygen unloading fro...
The elderly and patients with several comorbidities experience more severe cases of coronavirus disease 2019 (COVID-19) than healthy patients without underlying medical conditions. However, it is unclear why these people are prone to developing alveolar
As mitochondrial structure is intimately connected to OxPhos, abnormalities in the structural integrity of mi- tochondria and in mitochondrial associated membranes (MAM) will compromise OxPhos function [83,152–160]. We recently reviewed evidence showing that abnormalities in mito- chondria number, ...
