If the bacterium Staphylococcus aureus experiences a cost for maintaining one or more antibiotic-resistance genes, what would happen in environments that lack antibiotics?

#Unit 11. Evolution and Behavior
  1. These genes would be maintained in case the antibiotics appear.

  2. These bacteria would be outcompeted and replaced by bacteria that have lost these genes.

  3. These bacteria would try to make the cost worthwhile by locating and migrating to microenvironments where traces of antibiotics are present.

  4. The number of genes conveying antibiotic resistance would increase in these bacteria.

#Unit 6. System Physiology – Plant

The following statements are related to pentose phosphate pathway.

a) The first and third steps are oxidations with large, negative standard free-energy changes and are essentially irreversible in the cell

b) NADPH rises and inhibits the first enzyme in the pentose phosphate pathway. As a result, more glucose 6-phosphate is available for glycolysis

c) All the enzymes of the reversible reaction of the pentose phosphate pathway are located in the cytosol

d) The NADPH is used for biosynthetic reactions such as lipid synthesis and nitrogen assimilation in the cytosol
