Which of the following amines has the potential to act as a transporter for the bacterial secretion system? a. Type I b. Type II c. Type III d. Type IV. β-lactamase will inhibit a. Penicillin b. Cephalosporin c. Streptomycin d. Both a and b. ADP ribosylation of EF2 is carried out by a. Diptheria toxin b. Tetanus toxin c. Cholera toxin d. All of the above. Which of the following helps in pathogen establishment in the host? a. Pili b. Chitin c. Flagella d. Murein. Bacterial bioluminescence differs from firefly bioluminescence in use of a. ATP b. Luciferin c. Luciferase d. All of the above.
Understand the Problem
The question presents a set of multiple-choice questions related to microbiology and biochemistry, focusing on topics such as β-lactamase, ADP ribosylation, pathogenicity mechanisms, and bioluminescence differences between bacteria and fireflies.
Answer
c. Type III, d. Both a and b, a. Diptheria toxin, a. Pili, b. Luciferin.
The answers are: c. Type III, d. Both a and b, a. Diptheria toxin, a. Pili, b. Luciferin.
Answer for screen readers
The answers are: c. Type III, d. Both a and b, a. Diptheria toxin, a. Pili, b. Luciferin.
More Information
Type III secretion systems act as transporters for bacterial secretions. β-lactamase inhibits both penicillin and cephalosporin. ADP ribosylation of EF2 is carried out only by diphtheria toxin. Pili help in pathogen establishment by attaching to host cells. Bacterial and firefly bioluminescence differ in their use of luciferin.
Tips
Be careful not to confuse the secretion system types; only Type III is directly involved as a transporter. Note that both penicillin and cephalosporin are targets of β-lactamase.
