2-In an enzyme-catalyzed reaction, the rate of the reaction depends on which of the following at very low substrate concentrations? Select one: Neither enzyme concentration nor substrate concentration Enzyme concentration but not substrate concentration Substrate concentration but not enzyme concentration Both substrate concentration and enzyme concentration
Homework Answers
The rate of reaction will depends only upon the substrate concentration but not on enzyme concentration. Option (c)
Because As the substrate concentration is very low, all the enzyme molecules will form [enzyme-substrate] complex and will leads to the product. Thus enzymes will be in excess, and the concentration of enzyme will not affect the rate.

The rate of an enzyme-catalyzed reaction initially increases with an increase in the substrate concentration, but eventually reaches a maximum value, even though the concentration of substrate continues to increase. Which of the following best explains why? O As substrate concentration increases, the substrates preferentially bind with each other instead of the active site of the enzyme, and no additional catalysis occurs. As substrate concentration increases, the active sites of all the enzyme molecules become occupied with substrate molecules, and...
