UPDATED Actual Exam Questions and
CORRECT Answers
Amino acids are the monomers of proteins. Which functional group in the amino acid
determines its specific shape and function? - CORRECT ANSWER- ✔✔R group


In humans, excess blood glucose is stored in the liver and in muscle tissue in the form of
glycogen. Glycogen is a long chain of glucose molecules bonded together. Because of this,
glycogen is called a _____________________. - CORRECT ANSWER- ✔✔polysaccharide


Receptors that are __________ bind to chemicals outside of the cell, and this binding process
causes a chemical response on the inside of cells. - CORRECT ANSWER- ✔✔proteins


Steroids are classes of lipids that include cholesterol, sex hormones, and cortisone. Steroids
are not hydrocarbon chains like triglycerides, but instead contain four fused carbon rings.
Although steroids can bond to fatty acids, steroid molecules do not contain a fatty acid chain,
and the monomer of a steroid biomolecule is difficult to define. Which of these does NOT
correctly pair a steroid and its function? - CORRECT ANSWER- ✔✔Cholesterol is an
energy source.


Students in biology are studying the macromolecules of life. They used a calorimeter to
determine the calories in various types of food. Once the lab was completed, the students ate

was gone; nothing but a sticky paste in her mouth. Elaborate on what happened chemically
while chewing the saltine. Include the macromolecules present. - CORRECT ANSWER-
✔✔The saltine is a carbohydrate. and digestion took place in Monica's mouth thanks to
