Question

Which one of the following biological polymers is mismatched with its monomer? A) DNA — nucleotide B) protein — fatty acid C) starch — a-(D)-glucose D) fatty acid — Acetyl-S-coenzyme A E) isoprenoid — isopentenyl

Which one of the following is not soluble in water? A) Free amino acids B) Proteins C) Nucleotides D) Sugars E) Oils and fats

The term amphipathic refers to those molecules that are polar at one end and nonpolar at the other. The following is not an example of an amphipathic molecule. A) Cholesterol B) Sphingolipid C) Phospholipid D) All of the above E) None of the above

These amino acids would contribute to forming bridge salts in protein secondary and tertiary structures: A) Arginine, Lysine, Glutamic Acid, Aspartic Acid B) Methionine, C) Serine, Threonine D) Tryptophan, Tyrosine, Phenylalanine E) None of the above

A cell exchanges matter and energy with the environment, which is one of the characteristics of living organisms. From a thermodynamic perspective, a cell is… A) an open system. B) subject to the laws of thermodynamics: First, energy is neither created nor destroyed; and second, every energy transfer increases the entropy (disorder) of the universe. C) capable of absorbing electromagnetic (e.g. light) or chemical energy from the environment and release heat and waste products to its surroundings. D) All of the above. E) None of the above.

Explanation / Answer

1)B protein-fatty acid. the subunits of protein is amino acid and not fatty acid and hence it is a wrong combination

2)E oils and fats are not soluble in water

3)E none of the above. all the stated molecules are amphipathic

5)D all of the above apply to cells
