(a)
To explain: Whether xylose is moving up or down to its concentration gradient
Concept introduction: E. coli is the gram-negative bacteria. In the gram negative bacteria, there are several active transport systems working for concentrating sugars. The xylose is the mostly available sugar in nature. The xylose is utilized as a source of carbon and
To explain: Whether xylose is moving into or out of the cell.
Concept introduction: E. coli is the gram-negative bacteria. In the gram negative bacteria, there are several active transport systems working for concentrating sugars. The xylose is the mostly available sugar in nature. The xylose is utilized as a source of carbon and metabolized by means of pentose phosphate pathway.
(b)
