Penicillin inhibits bacterial growth by preventing the cross-linking during peptidoglycan synthesis. Why does penicillin not inhibit growth of archaeal cells? Group of answer choices Most archaeal cells have a cell wall, but it is not composed of peptidoglycan. Archaeal cells do not have a cell wall. Penicillin is unable to penetrate the lipid outer membrane that blocks access of penicillin to the peptidogycan crosslinking enzymes. Pencillin is unable to penetrate the S layer to reach the peptidoglycan layer underneath.

Your friend Jim Crackcorn has developed a new antibiotic that damages the integrity of the cell wall by breaking down peptidoglycan. Jim tells you that he predicts that gram positive bacteria, gram negative bacteria and archaeal cells will be equally sensitive to this antibiotic. Do you agree with Jim’s prediction? If you agree, explain in your own words why you agree. If you disagree, explain in your own words what you would predict and why.

AreExplain.there any differences in between functions of prokaryotic 29. (short answer) Antibiotics such as chloramphenicol interfere with the ability of bacteria to synthesize protein by targeting their ribosomes. Explain why ribosomes are a good target for a useful antibiotic. proteins. 30. (short answer) Why does oxygen kill obligate anaerobes? Obligate anaerobes. live onlu in absence of as oxygen, They do not possess the defenses that make aerobic life possible and therefore cannot survive in air. 31. (short answer) Parasitic bacteria, which live intracellularly in host cells, typically have smaller genomes than other bacteria. Why does this observation make sense? (Hint: it is NOT deletional bias.) 32. (short answer) Viruses variously depend on their host cell for parts of the viral replication and maturation…

All of these actually accurately describe the cell wall D. The linkages in the backbone chain are beta-1,3 linkages O E. The cell wall functions as a semipermeable
In the domain system of classification, prokaryotes are divided into two domains: Bacteria and Archaea. The two domains differ in all BUT one feature. Which feature do they have in common? Question options: They both have identical cell walls. They both have prokaryotic cells. They both thrive in extreme environments. They both are able to live only under anaerobic conditions.

All of the following are characteristics of the bacterial flagellum except: Select one: a. It has a hook-like insertion to a basal body in the cell wall. b. It is composed of protein c. It is used in conjugation d. Counterclockwise rotation moves bacteria forward All the following are characteristics of prokaryotes except: Select one: a. Prokaryotes have cell wall b. Prokaryotes have ribosomes c . Prokaryotes have organelles d. Prokaryotes lack a nucleus e. Prokaryotes have genes
What are the flaws ? Prokaryotes can live in many different environments. Anerobic organisms need oxygen to survive, while aerobic organisms can survive without oxygen. Autotrophs are organisms that can assemble high energy macromolecules for their energy. Chemotrophs are organisms that capture energy from light. Extremophiles are organisms that grow in extreme conditions like boiling water. Gram-positive bacteria have few layers of peptidoglycan, while gram-negative bacteria have many layers of peptidoglycan and are surrounded by an outer membrane. Harmful bacteria can cause illness like food poisoning. Helpful bacteria can be used in food production to make yogurt. The endosymbiotic theory states that some of the organelles in eukaryotes were once free living prokaryotes. This is supported by the mitochondria and cytoplasm since they have their own DNA and ribosomes. Harmful protists can cause diseases like malaria in humans and downy mildew in plants. Helpful protists can be…
