equilibrium
The number of amino acids in an actin monomer is - Ans:✔✔-375

Preassembled nucleaton sites in a living cell are equivalent to the intracellular preference for actin
filaments - Ans:✔✔-true
Intracellular preference for actin filaments - Ans:✔✔-is a way to look at the geography of the cell and

The ability of actin filaments to disassemble into small monomers - Ans:✔✔-two of the above
What causes a myosin II molecule to be able to form a bipolar fiber - Ans:✔✔-Calcium binding to
calmodulin.
The diameter of the actin filament is ...... nm - Ans:✔✔-7
Actin filaments will only assemble in parallel bundles - Ans:✔✔-false
The ability of actin filaments to disassemble into small monomers - Ans:✔✔-enables the building blocks
of actin filaments to move from one side of the cell to the other.
Transmembrane Proteins - Ans:✔✔-can move laterally and cannot flip 180˚in the membrane.
From the following, where would a proline residue be least likely to be? - Ans:✔✔-in the middle of an
alpha helix
The presence of 2 disulfide bonds near each other is a good thing when a stretch of protein is to be
immobilized. - Ans:✔✔-true
Submembrane cytoskeletons can provide shape to a cell - Ans:✔✔-true
Beta pleated sheets can provide a unique environment on one side of the sheet relative to the other side
of the sheet because of the types of side groups that can accumulate there. - Ans:✔✔-true
