Questions and Answers

What information does the graph in Figure 1 provide?

  • Relationship between the relative concentration of a substrate and the rate of an enzymatic reaction (correct)
  • Effect of temperature on two different types of enzymes
  • Effect of enzyme concentration on the rate of a reaction
  • Effect of substrate concentration on the rate of a reaction

What is the effect of increasing substrate concentration on the rate of the enzymatic reaction, as shown in Figure 1?

  • The rate of the reaction decreases to a plateau as the substrate concentration increases. (correct)
  • The rate of the reaction increases proportionally with the substrate concentration.
  • The rate of the reaction remains constant irrespective of the substrate concentration.
  • The rate of the reaction increases to a maximum rate, reaches a plateau, and then decreases as the substrate concentration increases

What can be concluded about the effect of increasing enzyme concentration on the rate of the enzymatic reaction based on Figure 2?

  • The rate of the reaction increases proportionally with the increase in enzyme concentration. (correct)
  • The rate of the reaction decreases as the enzyme concentration increases.
  • The rate of the reaction increases to a maximum rate, reaches a plateau, and then decreases as enzyme concentration increases.
  • The rate of the reaction remains constant regardless of enzyme concentration.

What is a possible explanation for why the rate of the enzymatic reaction levels off in Figure 1 and Figure 2?

Study Notes

Tangent Function

  • Domain: All real numbers except x = (Ï€/2) + nÏ€, where n is an integer
  • Range: (-∞, ∞)
  • Period: Ï€
  • x-intercepts: (nÏ€, 0), where n is an integer
  • y-intercept: (0, 0)
  • Vertical asymptotes: x = (Ï€/2) + nÏ€, where n is an integer
  • Odd function: f(-x) = -f(x)
  • Origin symmetry: Graph is symmetric about the origin

Cotangent Function

  • Domain: All real numbers except x = nÏ€, where n is an integer
  • Range: (-∞, ∞)
  • Period: Ï€
  • x-intercepts: (Ï€/2 + nÏ€, 0), where n is an integer
  • Vertical asymptotes: x = nÏ€, where n is an integer
  • Odd function: f(-x) = -f(x)
  • Origin symmetry: Graph is symmetric about the origin

Cosecant Function

  • Domain: All real numbers except x = nÏ€, where n is an integer
