About This Chapter
Enzyme Mechanisms - Chapter Summary
In this chapter on enzyme mechanisms, brief lessons cover topics like why enzymes are required for the daily functioning of your cells and the mechanism of enzyme activity. You will also gain a better understanding of how enzymes are used in the body. After completing the chapter, you should be able to do the following:
- Explain how enzymes work
- Recall the functions of coenzymes, cofactors, and prosthetic groups
- Provide an example of an enzyme mechanism
- List factors that positively and negatively affect enzyme activity
- Discuss the amount of energy required to start a biochemical reaction
Our instructors are skilled at helping you grasp concepts related to enzyme mechanisms, and a brief quiz is available for each lesson to test your knowledge. If you find yourself struggling with a concept, you can use the Help feature to submit questions to instructors.
1. What are Enzymes? - Definition & Explanation
In this lesson, you will discover what enzymes are, explore how they work, and learn why they're needed for your cells' day-to-day functions. The lesson concludes with a quiz to test your knowledge.
2. 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.
3. What Is the Mechanism of Enzyme Activity?
Have you ever wondered what an enzyme is and what it does? In this lesson, we'll learn what an enzyme is and how it does its job in the cell - the mechanism of enzyme activity. We'll also look at an example of an enzyme mechanism.
4. Factors that Affect Enzyme Activity
This lesson focuses on enzyme activity. We'll go over what an enzyme is and how it's used in the body. We'll also look at the different factors that affect enzyme activity, both positively and negatively.
5. Enzyme Activity: Biology Lab
The amount of energy necessary to start a biochemical reaction is called activation energy. Special proteins called enzymes lower activation energy, allowing life to exist. In this lesson, explore how enzymes work and see what conditions affect them.
