Answer:
a. add more of the enzyme.
Explanation:
Enzymes speed up the rate of reaction by lowering the activation energy for the reaction. They are not used themselves in the reaction. They are specific to substrate molecule. Substrate molecule binds to enzyme's active site and they undergo the reaction to form the product and release back the enzyme.
Rate of reaction depends on both substrate and enzyme concentration. Maximum rate of reaction is reached when all the active sites of enzyme molecules have been occupied by the substrate molecules which means that they are saturated. If more substrate is added at this point it wont have any effect on rate of reaction since there are no free active sites. Hence more enzyme is required to be added so that extra substrate can be utilized and rate of reaction can further be increased.
Hello.
This statment is true.
Have a nice day
The answer is C. The method which involves counting the number of organism in a specific area is sampling. It is one common method to estimate the population of certain organisms used by biologists. In a given range, the number of plot is determined and per plot the number of individuals is multiplied to the number of plots then this results to an approximate population size.
