chambers A and B are placed next to each other but are separated by a film permeable to both glucose and fructose. chambers A co
Molodets [167]

Answer:

2.glucose move into chamber B faster than fructose

Explanation:  

  • Facilitated diffusion: refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this <u>passive transport</u>. If uncharged molecules need to be carried <u>this process depends on concentration gradients</u> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.  Facilitated diffusion is a passive transport process because the cell does not need any energy to make it happen.  

The exposed scenario is an example of facilitated diffusion, a process that occurs in favor of the concentration gradient, and which rate depends on the concentration of molecules in each side of the membrane, in this case, glucose and fructose, among other factors that might also influence the diffusion rate. So, as the concentration of glucose is higher in chamber A (80%), and lower in chamber B (20%), in comparison with fructose, the first one will diffuse faster than fructose. The difference in concentration between both chambers is sharper in glucose, so its transport is faster than the fructose transport, which will also diffuse but at a lower rate.

Which of the following is true of kinesin?
3241004551 [841]

Answer:

C. Kinesin hydrolyzes ATP.

Explanation:

The central force-generating element that the two types of motor proteins (Kinesin and Myosin) have in common includes the site of ATP binding and the machinery necessary to translate ATP hydrolysis into an allosteric conformational change. Kinesin must use the energy derived from ATP binding and hydrolysis to force a large movement in part of the protein molecule. When kinesin forms a rigor-like tight association with the head location of the microtubule, the ATP is bound to the kinesin, and it is hydrolysis of ATP that promotes release of the motor from its track. Thus, myosins can typically drive filament sliding much more rapidly than kinesins, even though they hydrolyze ATP at comparable rates and take molecular steps of comparable length.
