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.

Enzymes are biocatalyst they accelerate the chemical reaction. They are organic, all enzymes are made of protein but not all enzymes are protein. Certain biological reactions can be catalyzed by RNA called Ribozyme. Protein is a dynamic molecule; its activity depends on the three-dimensional structure. For example, the water droplet size gets flexible, if you touch. Protein folding and three-dimensional structures are vital for activity.  There is no living cell without an enzyme, in the living cell; it functions to accelerate the biological reaction. There is a misfolded protein infectious agent called Prion, which causes normal brain protein to misfold which, leads to neurodegratative disease. This module presents concise notes of enzyme basic concepts; bioinformatics tools and few examples of enzymes in everyday life.

Rating
0.0 stars

After studying the basics of enzyme function, students will be exposed to the history and evolution of lactose intolerance/lactase persistence. Both whole group and individual activities will ask students to interact with the concept. They will conduct a lab to understand the role of enzymes in lactose digestion and communicate their knowledge by creating a public health poster.

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.

Lesson 2: Absorbance Curves: Using spectrophotometers to quantize the effects of a strong acid on a buffer

Educational Use
Rating
0.0 stars

Chemical kinetics and buffers are two topics that are extremely difficult for students to understand. Combining the two topics will allow for a staggered, repetitive approach to teaching students to understand of how these two topics in chemistry actually work. Students will both qualitatively and quantitatively track the effect and enzyme has on a reaction, calculate the reaction rate and buffer capacity. Students will use a variety of lab techniques including calculations using Beer’s Law and spectrophotometry.
