Question
Chapter 3.7, Problem 1MC
Summary Introduction
To explain:
The reason that researchers determine how both magnetism and oxygen guide bacteria for movements.
Concept introduction:
Bacteria are small unicellular prokaryotic organisms without a predefined nucleus and the presence of a single chromosome inside the cytoplasm called as nucleoid. There are respiratory mesosomes present for respiration and ribosomes for the synthesis of proteins. They have flagella for locomotion and motility in fluids.

What is the endosymbiotic theory? Discuss two lines of evidence that support the theory.
1) The inactivation of Staphylococcus aureus was studied in pomegranate juice heated at 75°-
95°C. The slopes for the inactivation of this bacteria were calculated from the linear lines in
semi-log graphical paper. The slope values were presented in Table 1.

- In the experiment by Bernard Davis, bacterial F+cells and F- cells were growing while separated by a filter. Filter pores allowed the passage of the liquid medium but not the bacteria cells. As a result: 1) prototype colonies grew well on minimal medium 2) F+ cells were converted to F- cells despite the physical separation 3)F- cells were converted F+ cells despite the physical separation 4)F+ cells were not converted to F- cells because of the physical separation 5) F- cells were not converted to F+ cells because of the physical separation 6)there was no growth of prototypes on minimal mediumarrow_forwardWhy did the researchers choose one plant mitochondrion and fivebacterial species to include in the comparison matrix?arrow_forwardIn a reproduction of an experiment famously performed by Louis Pasteur, you cultured yeast in the absence of oxygen (anaerobic growth) and measured (1) the rate of cell division, (2) the rate of glucose consumption, and (3) the intracellular ATP:ADP ratio. You then moved the cells to an incubator containing normal atmosphere (i.e., 21% oxygen), completed a second set of measurements, and made the following observations: The rate of cell division increased considerably after the addition of oxygen (aerobic growth) Glucose consumption dropped dramatically after the addition of oxygen Intracellular ATP:ADP ratios increased significantly (from 2:1 in the absence of oxygen to 10:1 in the presence of oxygen) Explain how the mitochondria in the yeast contribute to the dramatic drop in glucose utilization and increase in ATP concentrations in the presence of oxygen.arrow_forward
