How do large molecules move across the cell membrane through facilitated diffusion?

Biology
1 answer:
Svetlanka [38]3 years ago

Answer:

Explanation:

In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.

Mama L [17]
During pulmonary edema, the interstitial space increases resulting to a smaller diffusion.  The increased interstitial space makes oxygen not to have enough time to reach the red blood cell resulting to partially oxygenated blood. Using the Fick equation there will be an increase in the level of oxygen coming from the lungs.

Aleksandr-060686 [28]

Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.

For taking bath, water at 40⁰C is required. Calculate the mass of cold water at 15⁰C which is to be added in 60 Kg water at 100⁰
MrRa [10]

Answer:

Energy added to cold water, E1

E1 = m•Cp•ΔT = 6 x 4.187x(42-20) = 6x4.187x22

Energy lost by hot water, E2:

E2 = X(CpΔT) = X x 4.187 x (75-42) =X x 4.187 x 33

So, since E1 = E2

6x4.187x22 = X x 4.187 x 33

X = 6x22/33 = 4.0kg

So the mass of the hot water added to the 6kg of cold water is 4.0kg
