The diagram below shows three different proteins embedded in a cell membrane, as well as the concentration gradient surrounding the cell high concentration channel protein carrier protein lipid bilayer 1 21 3 low concentration Which of the following statements correctly states the process shown in the diagram? O The process labeled 1 shows how cells can easily move molecules with the concentration gradient using high energy molecules. The process labeled 2 shows how cells move molecules against the co entration gradient without needing hic energy molecules The process labeled 3 shows how cells use energy to facilitate the active transport of molecules against the concentration gradient All three processes show how molecules freely move in and out of the cell regardless of the concentration gradient or available en Previous

Do you think there are concentration gradients? If so, for which ions are there concentration gradients? Specify whether the concentration values of these ions are higher or lower inside the cell.

1.2. Compare and contrast between the ATP-dependent movement employed by kinesin-1 and myosin II along their relevant cytoskeletal structure. 1.3. Monastrol is a kinesin-5 inhibitor and has the potential to be used as an anticancer agent. Discuss how this may affect mitosis. 2.1. The lipid bilayer is asymmetrical. Discuss why this is important for cellular function. Use an example to support your answer.

Urgent help needed   Watch the following movie clip from Lord of the Rings: The Fellowship of the Ring. In this clip, Gandalf the Wizard stops the fire demon from passing across the stone bridge. Explain how this clip is similar to the role of the plasma membrane. Use as much detail (about the membrane, not the movie) to support your answer.
