1. Which of the following is an example of a molecule with an amine group?
Why?
CH3COOH
CH3SH
CH3NH2
CH3OH
2. It shows how atoms are bonded to one another in a molecule.
Lewis Formula
Chemical Formula
Molecular Formula
Experimental Formula
Empirical Formula
Structural Formula
3. Describe the relationship between the number of carbon atoms and
hydrogen atoms in pentane.
Pentane has three carbon atoms and eight hydrogen atoms, which is
characteristic of cyclic compounds.
Pentane has four carbon atoms and ten hydrogen atoms, which is
typical for alkenes.
Pentane has six carbon atoms and fourteen hydrogen atoms,
indicating it is a saturated hydrocarbon.
, Pentane has five carbon atoms and twelve hydrogen atoms,
following the general alkane formula CnH2n+2.
4. If a new lipid molecule is discovered that remains liquid at room temperature,
how would it be classified in relation to traditional fats?
It would be classified as a fat.
It would be classified as an oil.
It would be classified as a protein.
It would be classified as a carbohydrate.
5. Peroxisomes are eukaryotic cellular organelles that...
contain DNA and a double membrane.
serve as an oxidative defense, by removing hydrogen peroxide
from the cytoplasm.
produce and contain hydrogen peroxide, a strong oxidizing agent.
are produced by budding from the endomembrane system of the
Golgi apparatus, and are immediately exported from the cell.
6. Describe the significance of ATP in the metabolic pathway involving fructose-
6-phosphate and fructose-1,6-bisphosphate.
ATP is used to break down fructose-1,6-bisphosphate.
ATP is produced during the conversion of fructose-6-phosphate to
fructose-1,6-bisphosphate.
ATP has no role in this conversion.
ATP is consumed to phosphorylate fructose-6-phosphate,
converting it to fructose-1,6-bisphosphate.
,7. Describe how water's polarity affects its role as a solvent in biological
systems.
Water's non-polar nature prevents it from dissolving any substances.
Water's low density allows it to act as a solvent for lipids.
Water's high viscosity enhances its ability to dissolve gases.
Water's polarity allows it to dissolve many ionic and polar
substances, making it an effective solvent in biological systems.
8. What is the major end product of purine metabolism that is responsible for
gout?
Glucose
Urea
Creatinine
Uric acid
9. In a biochemical experiment, if hydrogen bonding is disrupted, what effect
might this have on protein structure?
It would enhance the protein's functionality.
It could lead to denaturation of the protein.
It would increase the protein's solubility.
It would have no effect on the protein structure.
10. During ATP synthesis by oxidative phosphorylation
hydrogen ions pass from the intermembrane space to the
mitochondrial matrix, activating ATP synthase
, hydrogen ions pass from the mitochondrial matrix to the
intermembrane space, activating ATP synthase
11. Which of the following is an element not typically found in living organisms?
S
Br
Na
Ca
H
12. If a eukaryotic cell has defective lysosomes, what impact might this have on
the cell's ability to function properly?
Enhanced protein synthesis
Improved genetic information storage
Increased ATP production
Impaired digestion of macromolecules
13. According to the fluid mosaic model of cell membranes,
basic membrane structure results from how the proteins interact with
water
the membrane is a highly mobile mixture of phospholipids and
proteins
the most common type of molecules in the membrane are proteins
the unique properties of cell types are determined by their
phospholipids
