Which are examples of carbohydrates? A. Starch, glucose, fructose B. Cellulose, glycogen, protease C. Cholesterol, wax, carcinogen D. Trypsin, lipase, testosterone {Ans: A. Starch, glucose, fructose}If you wanted to increase the rate of an enzyme-catalyzed reaction, what would you do? Discuss A. Decrease the amount of substrate by one-third B. Increase the pH by 4 levels on the pH scale C. Decrease the amount of enzyme by half D. Increase the temperature by 10 C {Ans: D. Increase the temperature by 10 C. Because increasing the temperature will make the molecules move faster, thus increasing the amount of collisions between substrate and enzyme. all the other three decrease rate: reducing the amount of substrate or enzyme reduces chances of collison, while changing the pH more than 1 number will most likely cause the enzyme to denature.}Complete the analogy -lock : key :: enzyme : _________. Discuss A. Substrate B. Active site C. Product D. Protein {Ans: A. Substrate (although "induced fit" is the best model now, the enzyme and substrate fit together like puzzle pieces, or like a lock and key. the enzyme is the lock, while the substrate is the key.)}A feature of nucleic acids not
