- How do cells maintain the fluidity of their membranes? If a bacterium was growing at 20°C, how would it's membrane composition change if it was suddenly moved to cultivation temperature of 30°C.? How would it's membrane composition change if it was subsequently moved to a cultivation temperature of 10°C?The structures that enable some Gram-positive bacteria to remaindormant for extremely long periods of time are known asa. akinetes. b. endospores. c. biofilms. d. lipopolysaccharide envelopes. e. pili.A bacterial culture contains 500 cells/mL in the exponential growth phase at 8 AM. If you onsider a generation time of 20minutes, what will be the total number of cells/mL after three hours?
- Which of the following is present in both gram-positive and gram-negative cell walls?a. an outer membrane b. peptidoglycanc. teichoic acidd. lipopolysaccharidesChoose pne of these choices: A. Water molecules will still be able to move across the cell membrand but at a slkwer rate. B. Water moleces will no longer be able to move across the cell membrane. C. Water molecules will move across the cell membrand at a faster rate without the aquaporin regulating their flow. D. Water molecules will only be able to enter the cell by active transport.For any antibiotic compounds that don’t appear to inhibit translation of proteins from the ribosome, purpose another potential mechanism whereby this class of antibiotic might be able to act (outside of cell wall/membrane formation). Explain in deatil.
