Which of the following is an active transport mechanism?

a. Proton pump

b. Ion channel

c. Symport

d. Osmosis

Expert Solution & Answer

Summary Introduction

Introduction:

Active transport mechanism is the transport method that requires energy to move the particles against the concentration gradient.

Answer to Problem 1U

Correct answer:

Proton pump is a type of active transport mechanism that requires energy to transfer proton against the concentration gradient. Therefore, option a. is correct.

Explanation of Solution

Reason for correct statement:

The transfer of the protons from a lower concentration to a higher concentration is done with the help of the energy molecules. The process of utilization of ATP molecules for the transfer of the protons against the concentration gradient is known as proton pump.

Option a. is given as “Proton pump”.

As, “the proton pump is a type of the active transport mechanism that requires energy for the transfer of the protons between the layers,” is the right answer.

Hence, the option a. is correct.

Reasons for the incorrect statements:

Option b. is given as “ion channel”.

The transportation of ions from higher concentration towards lower concentration is done through the help of the ion channels. So, it is a wrong answer.

Option c. is given as “symport”.

The transport of two or more molecules together across the membrane is known as symport. So, it is a wrong answer.

Option d. is given as “osmosis”.

The process in which solvent moves from the semi permeable membrane form lower concentration to higher concentration is known as osmosis. So, it is a wrong answer.

Hence, options b, c, and d are incorrect.

Conclusion

Active transport mechanism requires the energy produced by the cell for the transport of the molecules 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
