Two bowling balls are rolling down lanes in a bowling alley. The kinetic energy of each bowling
ball depends on the bowling ball's mass and speed.

E. Increased concentrations of sugars such as arabinose in the cell.

Explanation:

Here, after different tests and many different combinations of carbon and nitrogen sources, on a reasonable variety of laboratory and naturally occurring strains, it was found that under some poor nitrogen sources such as certain amino acids, glucose becomes one of the worst carbon sources, supporting lower growth rate than other sugars. This is due to very low cAMP levels that are suboptimal for growth: growth can be improved by experimentally increasing cAMP levels, by either adding external cAMP, genetically manipulating cAMP levels, or inhibiting glucose uptake.
