describe in detail 2 mechanisms of how a sodium cation (Na+) can get into a prokaryotic cell.
Homework Answers
1. Passive transport - it includes the diffusion sodium ion from the region of high concentration towards the region of low concentration, across the membrane. which is along the concentration gradient. sodium ions pass through the membrane proteins. it is a passive transport because the energy required for ion movement originates from the ion gradient itself, it does not require ATP molecule.
2. Active Transport - it includes the movement of sodium ion across the plasma membrane with the use of ATP the energy-rich molecule. it moves from a region of low concentration towards the high concentration, which is against the concentration gradient.
example- sodium-potassium pump

chromatography mechanisms
-In ion-exchange mechanism of chromatography, let assume we use cation exchangers, cation will attract to stationary phase and remain binded untill we change th PH to get that cation my question is what I do with PH, raised it decrease it to get the cation? and why? -the same for the covalently binding of protein and antigen in affinity chromatography mechanism, how can I get the protein from antigen? is it by using PH (increa decrease)? of course,...

A. Describe in detail the regulation of the prokaryotic lac operon for the following environment: Glucose is present, lactose present, & the repressor protein is mutated such that the allosteric site is non-functional and can no longer bind its substrate. Be sure to specify the presence or absence and location of Lac I, allolactose, cAMP, CAP, and RNA polymerase. B. Indicate whether transcription is occurring at a basal level, a high level, or not at all.
