Summary Introduction

To determine:

The mechanism of the sodium-potassium pumps, which helps in moving ions across the cell membrane.

Introduction:

The plasma membrane is a semi-permeable membrane which allows certain molecules to move in and out across the membrane. There is a different mechanism like osmosis, diffusion, and active transport. The sodium-potassium pump moves ions across the cell membrane by the process of active transport.

Expert Solution & Answer
Check Mark

Explanation of Solution

Active transport uses energy to move molecules against a concentration gradient. The cytosol of animal cells contains a concentration of potassium ions (K+) much higher than that in the extracellular fluid. These concentration gradients are established by the active transport of both ions. It uses the energy from the hydrolysis of ATP to actively transport three molecules of Na+ ions out of the cell for every two molecules of K+ ions pumped into the cell.

Conclusion

Active transport is the movement of molecules across a membrane from a region of their lower concentration to a region of their higher concentration, in the direction against the concentration gradient.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?  3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
