SC.912.L.18.11

This lesson focuses on the role of enzymes as biological catalysts. The resource contains a lab that demonstrates enzyme reactions and a worksheet with activities for the students to select from.

Type: Lesson Plan

Students will predict, investigate, observe, and report on the effects that pH, concentration, and temperature have on catalase enzyme reactions. Students will conduct an experiment in which they will alter the pH, concentration, and temperature of the environment in which catalase enzyme reactions are taking place. Students will be able to describe how changes in these environmental conditions affect the action of the enzymes in living things.

Type: Lesson Plan

In this lesson, students work from lower to higher levels of scientific inquiry while studying enzyme kinetics in a practical, student-centered, flipped-classroom process. In addition to reviewing the importance of enzymes to biological systems and examining the factors that influence their activity, this is a good lesson to practice the scientific method, from replication of pre-designed experiments to asking questions, designing investigations, collecting and analyzing data, sharing findings, and engaging in peer review. Designed for higher-level classes, this lesson can be modified, simplified, or shortened for regular and honors classes.

Type: Lesson Plan

In this lesson, students will learn how important enzymes are by functioning as a catalyst in most all biological processes. In learning about the functions of enzymes, they will also see how they are related to things they come across in everyday life. Students will observe the breakdown of hydrogen peroxide by catalase from potatoes.

Type: Lesson Plan

This lesson will demonstrate enzyme-substrate complex and how they work in a biochemical reaction. It will also introduce factors that effect the rate of enzyme activity. Students will be asked to model enzymes and how they work in a biochemical reaction by interacting with an egg as the reactant/substrate and producing a fried egg over easy. Students will be asked a series of questions along the way and later will work in small groups to come up with their own model of a short biochemical pathway (1-2 steps) and identify the enzymes involved in the process. The model or process they choose should come from their every day experiences.

Students design an experiment to determine the effects of pH and temperature on enzyme activity in apples.

Type: Lesson Plan

Students learn about enzyme function, enzyme specificity, and the molecular basis for lactose intolerance.

Type: Lesson Plan

At any instant in your life, millions and millions of enzymes are hard at work in your body as well as all around you making your life easier!

By the end of this tutorial you should be able to describe how enzymes speed up most biochemical reactions as well as identify the various factors that affect enzyme activity like pH and temperature.

This tutorial will help you to understand the role that vitamins play in human nutrition. Vitamins interact with enzymes to allow them to function more effectively. Though vitamins are not consumed in metabolism, they are vital for the process of metabolism to occur.

This challenging tutorial addresses the concept at a high level of complexity.

Type: Tutorial

Chemical reactions are constantly happening in your body -- even at this very moment. But what catalyzes these important reactions? This short video explains how enzymes assist the process, while providing a light-hearted way to remember how activation energy works.

Type: Tutorial

This video shows an enzyme reaction lab. The teacher demonstrates how the enzyme, catalase, reacts with hydrogen peroxide (a substrate found in cells). The teacher first demonstrates a normal enzyme reaction. He or she then goes on to show how manipulating temperature and pH will affect the reaction of an enzyme.
