Quizplus · Accepted Answer

Escherichia coli is primarily a facultative anaerobe that can utilize a wide range of carbon sources for energy and growth. Among the given options, glucose is the preferred carbohydrate for E. coli as it can be metabolized through the Embden-Meyerhof pathway (glycolysis), which generates ATP and intermediates for biosynthesis. E. coli can also use other carbohydrates, such as lactose, maltose, and sucrose, but they require additional enzymes and regulatory mechanisms for their utilization, which are not as efficient as for glucose. Starch is a complex carbohydrate that needs to be hydrolyzed to glucose before E. coli can use it as a carbon source.
