Question

Which of the following is true?A) We can only get energy from the carbohydrates we eat. The rest of the macromolecules not broken apart, they are stored in the body or released as waste.B) The protein molecules that we eat are separated from the rest of the food and added directly to our muscle tissue to create more muscle.C) Glucose provides energy and atoms for cells to use. Most of the atoms we need to build our cells are available in carbohydrates like glucose.D) The human body is made of organic compounds, so we have to eat organic food to stay alive.

Answer 1

Let's analyze each statement:

A is false because even if we obtain energy primarily from carbohydrates, we can also obtain energy from proteins and lipids.

B is false because proteins are not only used to create more muscle but are needed for several functions in the cells.

C is true because glucose does provide energy and atoms for the cell to use, and carbohydrates are composed of carbon (C), hydrogen (H), and oxygen (O), that are three of the four more common elements in living organisms, the fourth is nitrogen (N).

D is false because organic food doesn't mean it has organic compounds (based on carbon), but refers to the methods followed to produce it
