Antioxidant Enzymes: Three or Four Veggies a Day Keeps Aging Away
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

The purpose of this video lesson is to expand the student's knowledge about enzymes by introducing the antioxidant enzymes that are intimately involved in the prevention of cellular damage and eventual slowing of the aging process and prevention of several diseases. Students will learn that natural antioxidant enzymes are manufactured in the body and provide an important defense against free radicals. The topic of free radical action is introduced, covering how they are constantly generated in living cells both by ''accidents of chemistry'' and also by specific metabolic processes.

The structure of enzymes moderates their function in chemical reactions in living things. Enzymes are a group of proteins that function to moderate the rate of metabolic reaction by acting as catalysts (Enduring Understandings of BIO.2c).This module was developed by Kristin Scheible as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.

How Enzymes Work: Investigating Their Specificity and Susceptibility to Environmental Factors Using Jell-O
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

This activity is a lab investigation in which students design and conduct experiments using pineapple juice containing the enzyme bromelain and its affect on the substrate gelatin found in Jell-O. The focus of student driven investigations are on enzyme specificity, activity and the impact of environmental factors on enzyme functioning. Based on the original activities from School Improvement in Maryland; "Pineapple/Jell-O Lab," Access Excellence Activities Exchange; "Enzyme Labs Using Jell-O" by Anne McDonald and Michael O'Hare, and AP & Regents Biology; "Lab 8: Pineapple Enzymes and Jell-O Molds" by Kim B. Foglia.
