Integral membrane proteins... Choose all that could apply are bound to the membrane by only interacting with the phospholipid's polar head O contain many amino acids with hydrophobic residues O contain alpha-helical membrane spanning domains O would not be digested by trypsin in a permeabilized cell O interact with the phospholipid core of the phospholipid bilayer
In facilitated diffusion, what is the role of the transport protein? > View Available Hint(s) O Transport proteins allow solutes to move passively down their concentration gradient across the membrane. O Transport proteins provide the energy for diffusion of the solute. O Transport proteins provide a low-resistance channel for water molecules to cross the membrane. O Transport proteins provide a protein site for ATP hydrolysis, which facilitates the movement of a solute across a membrane. Transport proteins organize the phospholipids to allow the solute to cross the membrane.
Is there any receptor (s) on the interior / cytoplasmic side of tha plasma membrane ? If yes , discuss.
The movement of kinesin motor proteins involves both the motor domain and the linker domain. Describe the role of each domain in kinesin movement, direction of movement, or both. Could kinesin-1 with one inactive head efficiently move a vesicle along a microtubule?
Integral membrane proteins are not water-soluble. Why? How must these proteins differ from globular proteins?
"In most animal cells, minus end-directed microtubule motors deliver their cargo to the periphery of the cell, whereas plus end-directed microtubule motors deliver their cargo to the interior of the cell", is true or false.
Consider the artificial cell experiment below: Lactose = 2.0 M Ca+ = 0.4 M The ion channels in the membrane will allow Ca+ to pass freely, but nothing else. The starting conditions for the experiment are shown. Lactose = 0.1 M Ca+ = 3.0 M Rewrite the following statement to make it correct: "Eventually, there will be a net movement of water out of the cell because the inside of the cell is hypotonic compared to the environment."

1. (a) In class thus far, we have focused our membrane transport energetics discussions on the transfer of K+ ions. Of course, in the cell there are other ions that contribute to the overall resting membrane potential (Autotal). To estimate the overall resting membrane potential for the predominant ions present in the cell, we must first calculate the individual resting membrane potential. Using the Nernst equation discussed in class, and the values provided below, calculate A for each ion. lon K+ Na+ Ca²+ CI- [ion] outside cell 6 mM 145 mM 4 mM 90 mM [ion] inside cell 145mM 8 mM 0.001 mM 6 mM
From the image provided. 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.
