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...
How do carrier proteins transport substances across cell membranes? a) Describe one reason why it is important for cell membranes to be fluid. b) State two differences between facilitated transport and primary active transport across a cell membrane. c) Suppose a toxin is known to...

According to study materials, solutes don't move across membranes; only water does. How does this explain the ions in our blood that move across to carry out nearly all life functions? Explain conditions on how water, electrolyte, and acid-base are maintained in homeostasis. What does a hype...
In addition to explaining recent experimental results obtained by other groups, the researchers’ findings also describe a physical mechanism that could be used to pump water through nanotube membranes in next-generation nanofluidic devices. Provided by University of Illinois at Urbana-Champaign...
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...
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, ...
