Glucose is the preferred carbon source for Escherichia coli bacteria. Researchers isolated E coli, a strain of E coli with a single mutation that inactices a key enz study the effect of the mutation on glucose utilization and ATP production by the bacteria, the researchers add 2 10% E colibacteria to 400 mL of a growth
as a measure of the bacterial concentration over time
(a) Describe why monitoring the growth rate of the E coli bacteria is a useful indicator of the effect of the glycolytic enzyme mutation on the bacteria

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

2 (mutate)

3 (next generation)

option c is the correct answer.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
