n 1 1 How does ATP differ from a RNA nucleotide? Question options: ATP has deoxyribose instead of ribose ATP has a 3C sugar ATP and RNA nucleotide and identical ATP lacks an adenine ATP has 3 phosphate group Hide question 1 feedback Correct n 2 1 Making popsicles _____________the entropy of the system. Question options: increases decreases does not effect on 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? Question options: 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. Products of metabolic reactions are not easily digestible, so it would pass through the patient undigested.

She is correct – this is an example of how pharmaceutical companies create expensive drugs when a cheap solution would solve the problem. Each enzyme can catalyze multiple reactions. It is not feasible to provide enough of the metabolite to each cell directly. on C 6 H 12 O 6 + 6O 2 → 6H 2 O + 6CO 2 is an example of ________________. Question options: catabolism anabolism synthesis Hide question 4 feedback Correct n 5 1 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. Question options: True False on What is an example of potential energy? Select all that apply. Question options: concentration gradients light sound heat energy in chemical bonds on

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? Question options: There is not much energy in the glycosidic bonds of cellulose, but at least there is a lot of it. There is not much energy in the peptide bonds of cellulose, but at least it is very easy to break down The breakdown of cellulose into fructose is an endergonic reaction, but an enzyme can reverse the equilibrium Cellulose is very difficult to break down into glucose, but it contains a lot of energy. Hide question 7 feedback Correct n 8 1 Neostigmine is a drug used to treat the disease myasthenia gravis. The drug binds to the active site of acetylcholinesterase preventing breakdown of acetylcholine. This drug is a(n) Question options: noncompetitive inhibitor competitive inhibitor allosteric inhibitor allosteric activator Hide question 8 feedback Correct n 9 1 Glycerol and fatty acids can combine to make triglycerides. This represents a(n) Question options: hydrolysis reaction anabolic reaction degredation reaction aerobic reaction
