Answer

Brief Explanations:

  • Question 1: An amino - acid has an amino group ($NH_3^+$), a carboxyl group ($COO^-$), a hydrogen atom and an R - group. The amino group is $NH_3^+$.
  • Question 2: FAD, NAD and ATP all contain nucleotides. Creatine phosphate is an energy - storing molecule that does not contain a nucleotide.
  • Question 3: Carbohydrates include sugars, are the body's primary energy source, and are part of DNA and RNA (in the form of ribose or deoxyribose).

Answer:

Question 1: $NH_3^+$ Question 2: Creatine phosphate Question 3: All of the above are true of carbohydrates.
