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.

This course examines the chemical and physical properties of the cell and its building blocks, with special emphasis on the structures of proteins and principles of catalysis, as well as the chemistry of organic / inorganic cofactors required for chemical transformations within the cell. Topics encompass the basic principles of metabolism and regulation in pathways, including glycolysis, gluconeogenesis, fatty acid synthesis / degradation, pentose phosphate pathway, Krebs cycle and oxidative phosphorylation.

Course Format
This OCW Scholar course, designed for independent study, is closely modeled on the course taught on the MIT campus. The on-campus course has two types of class sessions: Lectures and recitations. The lectures meet three times each week and recitations meet once a week. In recitations, an instructor or Teaching Assistant elaborates on concepts presented in lecture, working through new examples with student participation, and answers questions.
MIT students who take the corresponding residential class typically report an average of 10–15 hours spent each week, including lectures, recitations, readings, homework, and exams. All students are encouraged to supplement the textbooks and readings with their own research.
The Scholar course has three major learning units, called Modules. Each module has been divided into a sequence of lecture sessions that include:

Textbook Readings
Lecture Notes or Storyboards
A video by Professor JoAnne Stubbe or Professor John Essigmann
Problem Sets and solutions

To help guide your learning, each of these problem sets are accompanied by Problem Solving Videos where Dr. Bogdan Fedeles solves one of the problems from the set.

Cells need energy to power the chemical reactions that keep their microscopic cities running, and most of that energy comes from a chemical called ATP. In this episode of Crash Course Biology, we’ll learn how our cells use energy, what an enzyme’s role is in chemical reactions, and what makes a reaction exergonic or endergonic.

Chapters:
Cellular Cities
What Is Energy?
The Laws of Thermodynamics
ATP
Chemical Reactions
Enzymes
Metabolic Pathways

Seeing how an inhibitor can "compete" for an enzyme with the intended substrate.

This series of instructional videos was created by Camosun College for a Canadian edition of the OpenStax "Concepts of Biology" open textbook as part of the BC Open Textbook Project. The lectures are taught by Charles Molnar, a Biology instructor at Camosun College. The videos are accompanied by transcripts.

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.

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.

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.

This course provides a brief introduction to the field of biocatalysis in the context of process design. Fundamental topics include why and when one may choose to use biological systems for chemical conversion, considerations for using free enzymes versus whole cells, and issues related to design and development of bioconversion processes. Biological and engineering problems are discussed as well as how one may arrive at both biological and engineering solutions.

Students are tasked with designing their own experiment to discover why you cannot add fresh pineapple to Jell-O. After analyzing their results, they will construct a CER that will be used to assess their understanding of the concepts.

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.

Join our team of young explorers on their mission to save nature from pollution! When this group of friends discovers the impact people have on their environment, they embark on a quest for justice and answers that quickly throws them into a whirlwind of adventures. Their goal: to find powerful molecules capable of solving the pollution problem. Get ready for an exciting journey through unexplored territories and discover the microscopic power hidden all around us. Be part of our quest for a greener world!

Dr. Bolander recently retired from the University of South Carolina, where he taught biochemistry at both the graduate and undergraduate levels for decades. He accumulated considerable figures and notes and is making them available to others involved with teaching biochemistry or related courses.

These notes cover material with weaker coverage in standard biochemistry textbooks. This text is supplemental rather than primary.

These learning activities are designed to be used in a large introductory chemistry course, each as part of a larger module of learning activities that include a prior reading of a short background information document. By working in small groups to discuss the presented information and question prompts, students will apply concepts seen in earlier coursework to explore a topic of societal or environmental relevance. No new conceptual information is delivered in these activities; rather they provide an opportunity to show students how the chemistry concepts they have developed support a detailed scientific understanding of a significant issue.Instructional resources for each activity  include 1) background information (.docx and .pdf) 2) the learning activity (.docx and .pdf) 3) the learning objects (.docx and .pdf) and 4) the slide deck (.pptx).These activities include exploration of:Methyl Transferase EnzymesNitrogen CycleOzone and Chlorofluorocarbons Mechanism of Penicillin Interior Salish Pit Cooking

This laboratory manual is intended for use in a biology laboratory course taken by non-science majors, pre-biology, and pre-allied health majors.

Laboratory exercises provide students with experience in basic laboratory skills, gathering and organizing data, measuring and calculating, hypothesis testing, analysis of data, writing, and laboratory safety. The skill sets are designed to promote the development of critical thought and analysis. Students work with living and preserved specimens, and laboratory reagents and equipment.

In this investigation, students will design experiments and gather data to observe the factors that influence the activity of enzymes.
