Answer:
The two main reasons are nonpolar core of the bilayer and the active transport.
Explanation:
The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.
If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.
One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>
Answer:
soluble molecules
Explanation:
Soluble molecules dissolve completely when mixed with water, hence forming a solution
C. Euglena are likely are obtain nutrition via photosynthesis.
Cytokinesis generally overlap with the typical cell cycle in the telophase stage. Telophase is the last stage of mitosis; where the sister chromatids reach opposite poles. Telophase and cytokinesis occur simultaneously, during cytokinesis the cell splits in two once the DNA has been replicated and pulled to opposite ends of the cell.
Answer:
solute
Explanation:
The cell membrane with an integral molecule that consists of two similar parts with a specific recess. There are many particles in the extracellular fluid. One of these particles is labeled A.
Structure A is a solute
Solute refers to the component which is dissolved in the solvent.
The solvent is the substance in which the solute is dissolved.
