Lesson: Factors Affecting Enzyme Action Biology • First Year of Secondary School

Students will be able to

• describe and explain the effect of temperature, pH, enzyme concentration, and substrate concentration on enzyme activity,
• define the terms optimum temperature and optimum pH,
• identify the active site of an enzyme,
• recall that enzymes will lower the activation energy of a reaction,
• recall that enzymes and their active sites are made up of proteins and that if conditions change substantially, the structure of these proteins can be changed to denature the enzyme,
• interpret graphical data to describe and explain changes in the rate of enzyme-controlled reactions.
