Which cell type has a thicker layer of peptidoglycan. The Gram negative cell is 1,000x thicker than the Gram positive cell. The Gram positive cell is 1,000,000x thicker than the Gram negative cell. The Gram positive cell is 1,000x thicker than the Gram negative cell. The Gram negative cell is 1,000,000x thicker than the Gram positive cell. The Gram negative cell is 10x thicker than the Gram positive cell. The Gram positive cell is 10x thicker than the Gram negative cell.Figure 22.16 Which of the following statements is true? Gram-positive bacteria have a single cell wall anchored to the cell membrane by lipoteichoic acid. Pori ns allow entry of substances into both Gram-positive and Gram-negative bacteria. The cell wall of Gram-negative bacteria is thick, and the cell wall of Gram-positive bacteria is thin. Gram-negative bacteria have a cell wall made of peptidoglycan, whereas Gram positive bacteria have a cell wall made of lipoteichoic acid.

- A cell is 5 µM in diameter. Express this in mm. mmWhy might clinical medicine have an interest in understanding bacterial cell division at the molecular level? Explain why a hyperthermophile would probably not be a human pathogen. Describe four factors that may have an influence on the effectiveness of an antimicrobial treatment. Explain why 70% or 80% alcohol is more effective than 100% alcohol in controlling microorganisms.Bacillis brevis are lysed using a valve-type homogenizer. The extent of disruption depends on the applied pressure and the number of passes through the homogenizer chamber and can be described by the equation, ln(1 − ?) = −????. Is Bacillis brevis a gram-positive or gram-negative bacterial cell? Based on this response, describe the cell wall structure and how it differs from the other type. Develop an equation for calculation of pressure as a function of the number of passes through the homogenizer. What factor(s) did you take into consideration when selecting the number of passes? Escherichia coli cells are lysed with the same homogenization, is this organism gram-positive or gram-negative? What impact does increasing the value of the constant, a, have on the required number of passes at a given pressure? What factors impact the value of a?

Include and label components associated with the membranes/cell walls Describe each phase of the BACTERIAL GROWTH CURVE (explain what happens, give the cells characteristics…).Gram-negative bacteria are surrounded by two membrane bilayers separated by a space termed the periplasm. The periplasm is a multipurpose compartment separate from the cytoplasm. The periplasm has a distinct oxidizing environment that allow certain key protein structural features to be formed. Can you identify an amino acid(s) that would be affected by this oxidizing environment? How would it be affected, and what structural features would be sensitive to this environment? Can you discuss the implications of this from a standpoint of recombinant protein expression?
