What cellular components do some bacterial cells have that make them powerful pathogens? Explain your answer. Bacterial cells are strong because they have pili, which help the bacterial cell attach tightly to other cells, and a capsule that protects the bacterial cell from destruction. 2. Why are penicillin’s often more effective against Gram-positive bacteria than Gram-negative bacteria? Penicillin is only effective against gram-positive bacteria because gram negative has endotoxins surrounding the cell wall. These endotoxins prevent the penicillin from attacking the bacterial cell. 3. Why is it important to understand the structure of a bacterial cell when developing an antibiotic? Knowing the structure of a bacterial cell helps develop an antibiotic by finding what enzymes and antigens are on the bacterial cell in order to make an antibiotic that can bind to these in order to attack a bacterial cell.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
