Upon centrifugation, particles sediment at different rates due to their physical properties. Tropomyosin is a rod-shaped protein
polet [3.4K]

Answer:

Elongated shape

Explanation:

Centrifugation separates molecules on the basis of angular motion.

Due to spherical shape, the value of 'f' is lesser for a spherical protien than the rod shaped one.

Hence the sedimentation coefficient for an elongated protien is 2.6S while htat of a spherical protien is 4.31S.

Hence its elongated shape results in slow centrifugation.

Some of the important principles of centrifugation are as follows :

  • The greater the mass, the more is the sedimentation rate i-e the one with greater mass will move down more rapidly as compared to the one with les mass.
  • Shape of particles also effect it, the rounder the particle, the lower frictional coeeficient.
  • Density of particles
  • Density of fluid

The shape of each of the molecules is important because A) if the shape of any molecule in an organism changes, the DNA in that
dexar [7]

Answer:

The correct answer would be - C) the shape of a molecule determines how it functions in chemical reactions

Explanation:

The molecular shape of the molecules is one of the important characters of the molecules. It is important due to the fact that molecular shape determines how a molecule will react and interact with other molecules.

The shape of the molecules determines boiling point, melting point as well as various chemical reaction by determining the bonds. For instance, H2O or water has a tetrahedral shape which affects its bonding and properties. If molecules were linear in  shape there would be no life existed.

Thus, the correct answer would be - C)
