a gram of glucose has 4 calories in it. a gram of ethanol has 10 calories in it. considering your knowledge of cellular metabolism and the second law of thermodynamics which states that some energy is released as heat every time energy is transformed which of the following selections fills i the blanms to make a true statement.

blank metabolism of 2.5 grams of glucose will result in the production of. blank grams of ethanol

a. asrobic 1

b. aerobic more than 1

c. anaerobic 1

d anaerobic more than 1

e. anaerobic less tha 1

Answer 1

The correct option is e. Anaerobic metabolism of 2.5 grams of glucose will result in the production of less than 1 gram of ethanol.

Because, aerobic metabolism of glucose will produce pyruvic acid and ATP, while anaerobic metabolism of glucose will produce ethanol. And, if a gram of glucose has 4 calories and a gram of ethanol has 10 calories then 2.5 grams of glucose will convert into 2.5x4=10. Hence, 10 calories will make 1 gram of ethanol, however due to loss as heat during conversation, the final amount will be less than a gram.
