Can a protein that is not part of the cell membrane diffuse through the membrane? If not, why?
Katyanochek1 [597]

Answer:

Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane. Although ions and most polar molecules cannot diffuse across a lipid bilayer, many such molecules (such as glucose) are able to cross cell membranes. ... Channel proteins form open pores through the membrane, allowing the free passage of any molecule of the appropriate size.t is the proteins, therefore, that give each type of membrane in the cell its ... Many extend through the lipid bilayer, with part of their mass on either side ..... Many hydrophobic membrane proteins can be solubilized and then purified in an active, if not entirely ..... Many Membrane Proteins Diffuse in the Plane of the Membrane.

hope this helps :)

During an interphase lasting 23 hours the S stage takes average 8.0 hours.What is the percentage of interphase is taken up by S
Alik [6]

The right answer is 34.78%

The interphase is the period of the cell cycle that the cell transcribes its genes and the chromosomes are duplicated. It can be subdivided into several phases:

* phase G1

* phase S: during which the chromosomal material is doubled by DNA replication. This is called chromosome duplication.

* phase G2.

Phase G1 is the longest phase of the interphase (its duration depends on the type of cell), followed by phase S, then phase G2.

To calculate the proportion of phase S in the interphase simply make the division:

phase duration S / interphase duration = 8/23 = 0.3478 (in percentage that is 34.78% (0.3478*100)).
