PAG04 = RATES OF ENZYME REACTIONS

Question 1

When investigating the effect of temperature on catalase

activity what is the independent/ dependant variable?

Answer 1

Independent variable​ = temperature

Dependent​ variable​ = rate of reaction

Question 2

When investigating the effect of enzyme concentration on amalyse enzyme
activity what is the independent/ dependant variable?

Answer 2

Independent variable​ = the concentration of amylase (enzyme concentration)

Dependent​ variable​ = rate of reaction

Question 3

When investigating the effect of substrate concentration on enzyme
activity what is the independent/ dependant variable?

Answer 3

Independent variable​ = the concentration of hydrogen peroxide (substrate concentration)
Dependent​ variable​ = rate of reaction

Question 4

What is a serial dilution?

Answer 4

produces ranges of concentration, give us relative concentrations
