How much of a 100 gram sample of gold-198 is left after 810 days if it’s half life is 2.7
Juliette [100K]

Answer:

mass₁=100.0g

time₁=2.70 days

mass₂=x

time₂=8.10 days

8.10/2.70 = 3

100/2 = 50/2 = 25/2 = 12.5 g

x=12.5 g

8-4 Discounting the Transverse Carrier Model. At one time, membrane biologists thought that transport proteins might act by bind
Natasha_Volkova [10]

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>
