1.	You want your bacterial culture to grow well so you made an enriched media with all forms of carbohydrates. Which of this carbohydrate should you restore first if you want the culture to keep growing at the same rate?(a) Glucose(b) Lactose(c) Galactose(d) FructoseThis question was posed to me in class test.My question comes from Operons : Lac and Ara topic in portion Gene Expression : Transcription Prokaryotes of Cytogenetics
Answer» CORRECT answer is (a) GLUCOSE Best explanation: Prokaryotes first use all the glucose in the media to derive energy. Only when they sense a low glucose level they search ALTERNATIVE energy SOURCES LIKE lactose, fructose or galactose.
