Detailed explanation-1: -Glucose is a ready source of energy, since its carbon atoms are easily oxidised (burnt) to form carbon dioxide, releasing energy in the process.
Detailed explanation-2: -In most conditions, glucose is the best carbon source for E. coli: it provides faster growth than other sugars, and is consumed first in sugar mixtures. Here we identify conditions in which E.
Detailed explanation-3: -Carbon is an essential element for all life forms on Earth. Whether these life forms take in carbon to help manufacture food or release carbon as part of respiration, the intake and output of carbon is a component of all plant and animal life.
Detailed explanation-4: -Glucose is a good carbon source because it is readily catabolized. Every cell has the required machinery to metabolize glucose at its disposal and it does not need to synthesize additional enzymes to isomerize other carbon sources of glucose which takes time and energy.
