AP BIOLOGY

Detailed explanation-1: -Enzyme concentration does not affect the enzyme activity directly as substrate concentration determine it until the presence of the substrate in an excess amount. Enzymes are the assemblage of protein subunits and hence function under specific temperature and pH range only.

Detailed explanation-2: -Several factors affect the rate at which enzymatic reactions proceed-temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

Detailed explanation-3: -Enzyme activity is affected by a number of factors including the concentration of the enzyme, the concentration of the substrate, the temperature, the pH, and the salt concentration.
