Need help, please. What charge does a protein molecule have?neutralpositivenegativeO The charge depends on the sequence.Please consider the following setup: A semi-permeable membrane separates two chambers (A and B). Both chambers contain ions (solute molecules) in water, but chamber Ahas a lower concentration of ions than chamber B. In which direction will the water move?ABSolutemoleculeWaterSemi-permeablemembraneThe water will flow into chamber A.O The water will flow into chamber B.O The water will remain in its respective chamber.True or False: A protein treated with sodium dodecyl sulfate (SDS) will generally retain its function.True.False.

Diffusion and osmosis are 2 processes that depict the movement of substances from higher concentration to lower concentration through a membrane. Diffusion is the movement of substances from higher solute concentration to lower solute concentration. While osmosis is the movement of substances from higher water concentration to lower water concentration. Both these processes occur only when there is a semi permeable membrane. A membrane that permits only few substances to enter is called a semi permeable membrane. When 2 solutions are separated by a semi permeable membrane, the solute moves from higher concentration to lower concentration. Water moves in opposite direction because the concentration of water is less when there is higher solute in a solution. So higher the solute, lesser the water content. In the question, solution A has lesser solute concentration than B. So solute moves from B to A. Then water must move in opposite direction. Thus, water moves from A to B. Correct option is: b) water will move into chamber BA protein is made up of amino acids. Thus, each amino acid carries a charge at particular pH. At neutral pH, most of the amino acids have no net charge but some amino acids have charge. Based on this charge they were classified as acidic (negative charged) and basic (positive charged) amino acids. But a protein can have varying composition of amino acids. The net charge of protein depends on which amino acid dominates in the protein. Therefore the correct answer is: d) charge depends on the sequence SDS or sodium dodecyl sulphate is a detergent that is used to denature the proteins and impart negative charge to them irrespective of the native charge of the protein. SDS also disrupts hydrophobic interactions of the protein. Thus, we may conclude that a protein treated with SDS cannot retain its function. The correct option is: False
