Portage Learning | Latest Study Guide
1. Which of these is unsaturated?
Laurate
Myristate
Oleate
Palmitate
2. If a food product is labeled as containing unsaturated fats, what implications
does this have for its health benefits compared to saturated fats?
Unsaturated fats are less stable and more likely to spoil than saturated
fats.
Unsaturated fats are more likely to be solid at room temperature.
Unsaturated fats contain more calories than saturated fats.
Unsaturated fats are generally considered healthier as they can help
reduce cholesterol levels.
3. Describe the significance of FADH2 in the electron transport chain (ETC).
FADH2 is converted into glucose during glycolysis.
FADH2 is a waste product of the β-oxidation pathway.
FADH2 donates electrons and hydrogens to the ETC, which helps
generate ATP through oxidative phosphorylation.
FADH2 acts as a substrate for the CAC, producing NADH.
,4. What term describes the phase in a metabolic pathway where energy is
produced?
Investment phase
Transition phase
Activation phase
Payoff phase
5. Describe the role of nitrogen in the structure of biomolecules.
Nitrogen is primarily involved in energy production.
Nitrogen does not play a significant role in biomolecules.
Nitrogen is only found in carbohydrates.
Nitrogen is a key component of amino acids and nucleotides, which
are essential for proteins and nucleic acids.
6. If a cell is deprived of oxygen, which pathway would be affected in its ability
to metabolize carbohydrates, and what would be the consequence?
The citric acid cycle would be affected, resulting in increased glucose
levels.
β-oxidation would be affected, leading to increased fatty acid levels.
The urea cycle would be affected, causing ammonia accumulation.
Glycolysis would be affected, leading to reduced ATP production.
7. If a reaction has a ΔG of -5 kJ/mol, what can be inferred about the reaction's
spontaneity?
The reaction is non-spontaneous.
The reaction requires energy input to proceed.
, The reaction is spontaneous.
The reaction is at equilibrium.
8. What are the two electron carriers produced during the breakdown of
biomolecules in energy production?
Acetyl-CoA and Citrate
ATP and ADP
Glucose and Pyruvate
NADH and FADH2
9. If a biomolecule lacks nitrogen, which of the following would most likely be
affected?
Water balance
Carbohydrate storage
Protein synthesis
Lipid metabolism
10. Describe the role of lipids in biological systems and how they differ from
carbohydrates.
Lipids are soluble in water, while carbohydrates are not.
Lipids are used for protein synthesis, while carbohydrates store
genetic information.
Lipids store energy and form cell membranes, while carbohydrates
primarily provide energy.
Lipids and carbohydrates serve the same function in cells.
, 11. What term describes a compound that decreases the activity of an enzyme?
Ligand
Coenzyme
Inhibitor
Activator
Substrate
12. Hydrogen and chlorine form the covalent bond HCl as shown in the diagram
below. Hydrogen has an atomic number of 1 and chlorine has an atomic
number of 17. Which of the following statements is true of this molecule?
The molecule is neutral and will not interact with other molecules.
The electrons circling each valence shell are shared equally between
atoms.
If dissolved in water, the aqueous solution will become more alkaline
or basic.
The bond is polar because the shared electrons are more attracted
to the large number of protons in chlorine.
13. Describe how the conformation of a globular protein affects its function.
The conformation of a globular protein is irrelevant to its function.
