Question

Suppose you have determined the overall critical concentration for a sample of purified tubulin. Then you add a preparation of cent Find to the centrosome and stabilized against disassembly. When you again determine the overall critical concentration, you find Explain why the overall critical concentration would change. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used. The overall critical concentration should be when tubulin polymerizes in the presence of the centrosome preparation. If the minus end cannot disassemble, the overall critical concentration should now be equivalent critical concentration of the end 1 1

Explanation / Answer

The process of adding or removing monomers depends on the concentration of -tubulin dimers in solution in relation to the critical concentration, which is the steady state concentration of dimers at which there is no longer any net assembly or disassembly at the end of the microtubule. If the dimer concentration is greater than the critical concentration, the microtubule will polymerize and grow. If the concentration is less than the critical concentration, the length of the microtubule will decrease.

Answers are as follows.

1). To the higher.

2). To the lower.

3). Positive.
