In this science activity, students read about enzymes and nutrition. Students also answer 2 comprehension questions about the reading.

In this chemical reactions worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with 34 clues.

In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...

Students explain the process of polymerization. In this chemistry lesson, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.

In this photosynthesis, disease and Immune System worksheet, students fill in the blanks with key terms to complete sentences about the transfer of energy from the sun to plants, enzymes as catalysts in reactions, homeostasis, the immune...

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

If you've ever felt a little drained ... try converting some ATP to ADP! Science scholars perform one of life's most important reactions using a simulated lab workbench. The fun-to-use interactive allows pupils to control the reactants...

In this chemistry of food worksheet, students complete 20 various types of questions related to food and nutrition. First, they complete a crossword puzzle with vocabulary terms. Then, students use the figure shown to write the...

In this anatomy worksheet, students complete 22 review questions in the format of short answer, table completion, and fill in the blank after finishing an online virtual experiment about the chemical and physical processes of digestion.

Although the points given on these slides are valid, the visual accessibility is poor. Consequently, many viewers would be distracted or entirely unable to view the presentation.  The content is a review of microorganisms and their...

Don't be fooled by the title - this biology quiz could serve as an AP biology or college-level biology quiz. Some of the molecules represented may be difficult to identify without seeing the textbook from which this is based. It could...

Students, in groups, experiment with Heat Blanching, Vitamin C Dip, and Sulfur Dioxide Dip to see if they can prevent enzymatic browning.

Students explain the basic concepts of polymerization. Students participate in a lab to create a crude preparation of carboxyl esterase and test its effectiveness in reducing the residual monomer in an emulsion such as paint.

Young scholars demonstrate the path of food in the body. In this biology lesson, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.

Young scholars compare and contrast the visible structures of three insects based on photographs. They differentiate characteristics of crane flies, ants, and wasps then create a simple classification system.

Enzymes create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for a chemical entity that increases the speed of a reaction is a "catalyst." Enzymes are biological catalysts - they...

How well do you know the relationship between enzymes and activation energy? This resource provides you with short quizzes and tutorials to provide feedback for those topics you don't understand.

Learn about the basics of enzyme kinetics graphs, and see examples of the graphs to understand the valuable data that is found on the graph. [12 min, 29 sec]

This is a good page for explaining the development and function of enzymes. It includes links to help with the chemistry and the biology that comes up.

[Free Registration/Login may be required to access all resource tools.] How catalysts work and their role in living things.

[Free Registration/Login may be required to access all resource tools.] Describes how enzymes speed up biochemical reactions.

Reactions in cells must be regulated and one way to do this is using allosteric molecules. These regulators can activate enzymes or inhibit them. This tutorial explains exactly how allosteric regulation works using words, narration, and...

[Free Registration/Login may be required to access all resource tools.] In this lesson, students will define enzyme, be able to discuss the role of enzymes in biochemical reactions, and summarize their importance to living organisms.

What is a catalyst? This Khan Academy resource includes examples of enzymes, acid-base catalysis, and heterogeneous (or surface) catalysis.
