Why is the α-anomer of d-glucose less likely to form than the β-anomer? A. The β-anomer is preferred for metabolism. B. The β-anomer undergoes less electron repulsion. C. The α-anomer is the more stable anomer. D. The α-anomer forms more in L-glucose. - ANSWEWR-B. The β-anomer undergoes less electron repulsion. Many double-displacement reactions are enzyme-catalyzed via the "ping pong" mechanism, so called because the reactants appear to bounce off the enzyme like a ping pong ball. These reactions typically have two reactants and two products. In a third-order reaction involving two reactants and two products, doubling the concentration of the first reactant causes the rate to increase by a factor of 2. What will happen to the rate of this reaction if the concentration of the second reactant is cut in half? A. It will increase by a factor of 2. B. It will increase by a factor of 4. C. It will decrease by a factor of 2. D. It will decrease by a factor of 4. - ANSWEWR-D. It will decrease by a factor of 4. Becoming a college graduate requires hard work and diligence in academics.
