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>
I think its C.
I hope this helps and please do correct me if im wrong.
Explanation:
Observations allow us to collect data that we can connect back to the central problem. From this data we can start to form hypotheses (predictions on possible solutions or outcomes).
I would support the factory if I lived 50 miles away from the planned factory location. However, I would be worried if I only lived one mile away from the planned factory, because of possible health effects, bad smells, and a potential decrease in property values.
<h3>What is Air pollution ?</h3>
Factories contaminate the air by blowing chemical vapors and smoke out through vents and smokestacks, and by burning waste in open dumps or incinerators.
- Exhaust from generators, diesel trucks, and buses also fill the air with dangerous gases.
- The amount of toxic gases that factories release into the air increases health and environmental damages. In factories, toxic materials and gases, like carbon dioxide and methane, are burned and pumped out into the atmosphere.
