1. In the hierarchic system of classi- family
fication, which of the following is
least inclusive?
2. Which of the following best de- Two hydrogen atoms covalently bonded to one oxygen
scribes the molecular structure of atom
water?
3. Which of the following about car- They contain only two elements: carbon and oxygen.
bohydrates is incorrect?
They contain only two elements:
carbon and oxygen.
They are polymers of sugars.
Their most important functions are
providing storage, structure, and
energy.
They form the backbone of impor-
tant molecules such as DNA and
RNA.
4. Which of the following is a lipid that steroids
is a component of cellular mem-
branes and a precursor to signifi-
cant hormones and drugs?
5. Which of the following correctly Unsaturated fats contain one or more double bonds in
identifies the difference between their hydrocarbon tail, while saturated fats contain no
saturated and unsaturated fats? double bonds.
6. Which molecules are considered Carbohydrates, lipids, proteins, and nucleic acids
the most important in biology?

7. The sum of all chemical reactions Metabolism
that occur in an organism is:
8. How are plant cells different from Plant cells have a cell wall; Animal cells do not have a
animal cells? cell wall
9. Where in the cell does active trans- plasma membrane
port take place?
10. Which of the following micro- Flagella
tubules can be used to move the
cell?
11. What is the function of lysosomes? digestion
12. What is the first step of cellular res- Glycolysis
piration when glucose is converted
to pyruvate?
13. What are the two catabolic path- Cellular respiration and fermentation
ways that lead to energy produc-
tion in a cell?
14. What is the role of water in photo- Supply electrons in the light reactions
synthesis?
15. What are the two categories of cel- Sexual reproduction and asexual reproduction
lular reproduction?
16. Which of the following about car- They contain only two elements: carbon and oxygen.
bohydrates is incorrect?
17. Saturated fats

contain no double bonds in their hydrocarbon tail. As
a result are solid at room temperature and are consid-
ered detrimental to your cardiovascular health.
18. Unsaturated fats contain one or more double bonds in their hydrocar-
bon tail. As a result are liquid at room temperature.
19. Phospholipids consist of two fatty acids bonded to a phosphate group.
The phosphate group is polar and soluble in water
whereas the hydrocarbon tail of the fatty acids is non-
polar and non-soluble in water. This quality is important
in the function of cellular membranes, including the
plasma membrane, as the molecules organize them-
selves in a way that creates a barrier to protect the cell.
20. Steroids are lipids that are a component of cellular membranes
and a precursor to significant hormones and drugs.
21. The sum of all chemical reactions metabolism
that occur in an organism is?
22. Lysosomes are the digestive system of the cell. Lysosomes con-
tain hydrolytic enzymes which allow them to hydrolyze
(break down) proteins, fats, sugars, and nucleic acids
taken into the cell as well as break down other worn out
organelles within the cell.
23. Ribosomes site of protein synthesis, makes protein
24. Vacuoles Cell organelle that stores materials such as water, salts,
proteins, and carbohydrates
25. Mitochondria Powerhouse of the cell, and is the cite of cellular respi-
ration
