Glycerol and fatty acids can combine to make triglycerides. This represents a(n)
A.aerobic reaction |
B.anabolic reaction |
C.catabolic reaction |
D.degredation reaction |
E.hydrolysis reaction |
How does ATP differ from a RNA nucleotide?
A.ATP and RNA nucleotide and identical |
B.ATP has deoxyribose instead of ribose |
C.ATP lacks an adenine |
D.ATP has a 3C sugar |
E.ATP has 3 phosphate group |
After many years of difficult research, your company invented a drug that increases the enzyme rate for the synthesis of an important metabolite. Patients with mutations in the enzyme lack the metabolite and have devastating symptoms. Your team is thrilled to have a drug that speeds up the enzymatic rate.
At your celebration, the new intern pipes up: “You guys didn’t have to do all that work after all! Instead of giving patients this new drug, you could have just given them the metabolite directly.”
Your response?
A.She is correct – this is an example of how pharmaceutical companies create expensive drugs when a cheap solution would solve the problem. |
B.Each enzyme can catalyze multiple reactions. It is not feasible to provide enough of the metabolite to each cell directly. |
C.It would have been much easier to give patients a small pill once a week containing the product of the reaction. But that compound was already patented by another company. |
D.Products of metabolic reactions are not easily digestible, so it would pass through the patient undigested. |
Researchers are working to develop biofuels to free us from dependence on fossil fuels. Based on what you know about cellulose, what do you predict are the major advantage and disadvantage of using cellulose-rich plant material as biofuel?
A.There is not much energy in the glycosidic bonds of cellulose, but at least there is a lot of it. |
B.There is not much energy in the peptide bonds of cellulose, but at least it is very easy to break down |
C.The breakdown of cellulose into fructose is an endergonic reaction, but an enzyme can reverse the equilibrium. |
D.Cellulose is very difficult to break down into glucose, but it contains a lot of energy. |
Since metabolism involves the synthesis and breakdown of non-protein cell components like mono- and polysaccharides, lipids, and ATP, there is not much role for gene mutations to influence the process.

A. heat |
B. light |
C. sound |
D. concentration gradients |
| E. energy in chemical bonds |
