About This Chapter
Who's it for?
Anyone who needs help learning or mastering college biology material will benefit from taking this course. There is no faster or easier way to learn college biology. Among those who would benefit are:
- Students who have fallen behind in understanding enzyme functions and interactions
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about enzymatic biochemistry
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Enzymatic Biochemistry chapter exam.
Why it works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the Enzymatic Biochemistry chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any enzymatic biochemistry question. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students will review:
In this chapter, you'll learn the answers to questions including:
- How do enzymes reduce activation or minimum energy during a chemical reaction?
- What are some of the environmental factors that affect enzyme function?
- What are coenzymes, cofactors and prosthetic groups?
- Why do cells activate or inhibit enzyme reactions?
1. Function of Enzymes: Substrate, Active Site & Activation Energy
In this lesson, we'll learn how enzymes function to lower the activation energy of a chemical reaction. Enzymes bind to their substrates to perform all kinds of important and essential cellular processes, as well as processes that help you enjoy a slice of pizza!
2. Enzyme Activity & Inhibition: Structure, Substrates, pH & Temperature
Enzymes appreciate the right working conditions. Can you blame them? We all work best in the correct environment. In this lesson, we'll learn how substrate concentration, temperature, and pH affect enzyme activity and structure.
3. Coenzymes, Cofactors & Prosthetic Groups: Function and Interactions
Some enzymes require helpers to recognize a substrate or complete a reaction. These helpers include cofactors, coenzymes, and prosthetic groups, which are required for some enzymes' functions.
4. Enzymatic Reactions: Inhibition and Regulation
Enzymes are generally not allowed to run uncontrolled in a cell. While they are useful in catalyzing reactions, there is a time and place for everything. In this lesson, we'll discuss enzyme activators and inhibitors that regulate these reactions positively and negatively, respectively.
5. Cooperativity: Definition & Explanation
This lesson covers cooperative binding, which is associated with allosteric proteins. Examples and graphs showing the differences between cooperative and non-cooperative binding curves will be discussed.
6. Nuclease: Definition, Function & Activity
In biology, we encounter many chemicals with the suffix 'ase' attached to them. This is fairly indicative of an enzyme that will break chemical bonds. In this lesson, we will look at nucleases and what bonds they break.
7. Active vs. Inactive Enzymes
Enzymes are proteins that do work in cells. All enzymes have a specific job to do, but sometimes they are not needed. For this reason, the cell has to have a way to control them. This lesson will explain how enzymes are activated or inactivated.
