What Are Enzymes Made Of?

MODULE #2

WHAT DO ENZYMES DO AND HOW DO THEY DO IT?

ESTIMATED TIME TO COMPLETE: Two 45-minute class periods

MODULE OBJECTIVES: Upon successful completion of this module the student shall:

Identify the components of an enzyme.
Identify factors that affect the rate of enzyme activity.
Define activation energy, active site, enzyme, catalyst, and substrate.
Identify the commercial, medical, and research values of enzymes

CONCEPT(S) LEARNED IN THIS MODULE:

Basic enzyme structure and function
The importance of enzymes to society

STANDARDS ADDRESSED BY UNIT MODULES:

Maryland State Department of Education High School Science Core Learning Goals (see www.mdk12.org)

Goal/Expectation	Indicator/Assessment Limit
Goal 1	The student will demonstrate ways of thinking and acting inherent in the practice of science. The student will use the language and instruments of science to collect, organize, interpret, calculate, and communicate information.
1.4	The student will demonstrate that data analysis is a vital aspect of the process of scientific inquiry and communication.
	1.4.1 - The student will organize data appropriately using techniques such as tables, graphs, and webs. (for graphs: axes labeled with appropriate quantities, appropriate units on axes, axes labeled with appropriate intervals, independent and dependent variables on correct axes, appropriate title)
	1.4.2 - The student will analyze data to make predictions, decisions, or draw conclusions.
	1.4.6 - The student will describe trends revealed by data.
1.5	The student will use appropriate methods for communicating in writing and orally the processes and results of scientific investigation.
	1.5.1 - The student will demonstrate the ability to summarize data.
Goal 3	The student will demonstrate the ability to use the scientific skills and process and major biological concepts to explain the uniqueness and interdependence of living organisms, their interactions with the environment, and the continuation of life on earth.
3.1	The student will be able to explain the correlation between the structure and function of biologically important molecules and their relationship to cell processes.
	3.1.1 - The student will be able to describe the unique characteristics of chemical compounds and macromolecules utilized by living systems. [structural and functional role of enzymes]

TECHNOLOGY-ENHANCED INSTRUCTIONAL STRATEGIES UTILIZED IN THIS MODULE:

Students participate in telecollaboration and telecommunication through the use of Blackboard; Internet search engines are employed.

Components Brief Description of
Module Activities Student
Grouping Materials / Technology

Engagement Students participate in a "silent" demonstration" of catalysis. Individual Blackboard Threaded Discussion

Exploration Students perform the "Toothpickase" activity to simulate enzyme action. Pairs Toothpicks

Explanation Post lab discussion Class Blackboard

Extension/ Elaboration WWW research is performed to answer three problems. Individual or small group WWW/electronic media, Blackboard Discussion Thread

Evaluation
(no supplemental files provided)
The product of the web-based search can be used for evaluation. Laboratory-based questions can also be used. It should be noted that informal evaluation occurs during each component of the module. Individual Blackboard Quiz

EXPECTED MODULE OUTCOMES:

Students will use appropriate scientific terms to describe the functions of an enzyme, such as substrate, product, activation energy, and enzyme-substrate complex.

PERFORMANCE-BASED ASSESSMENT OF MODULE OUTCOMES:

Students write abstracts to identify the practical applications associated with enzymes. A student-designed or teacher-designed rubric can be used to evaluate the abstracts.
