Question

Which of the following statements about energy is false? Select one: a. Is the capacity to do work b. Is stored in the bonds of molecules c. Can be transformed d. Is necessary for life e. Can be created Why do many people develop intolerance to lactose (milk sugar) as they get order? Select one: a. They are worn out from digesting milk products all their lives b. They no longer synthesize thee enzyme that breaks down lactose c. They lose their taste for milk products d. A, B and C are all true e. No one is intolerant to lactose- it is an urban myth

Explanation / Answer

16. According to the first law of thermodynamics, energy can not be created nor destroyed. Hence option E. Can be created is the answer.

Energy can be employed to perform work. Option a is true.

Energy is stored in the form of chemical energy. When a bond is broken, it may release energy. Hence option b is true.

Again, according to first law of thermodynamics, energy can be transformed from one form to the other. Hence option c is true.

Energy is essential for life. ATP is the energy giving molecule of all life forms. Hence option d is true.

17. Lactose is a milk sugar which is a disacharide. It formed by bond between glucose and galactose. To be able to digest milk products, one needs to have sufficient production of Lactase enzyme which is also known as beta galactosidase. It breaks the bond between glucose and galactose for the digestion of milk products. If one cannot produce enough lactase, it results in lactose intolerance.

So, the answer is option B.
