About This Chapter
Enzymatic Biochemistry - Chapter Summary and Learning Objectives
Did you know that many of the chemical reactions inside your body are regulated by enzymes? In this chapter, we'll take a look at enzymatic biochemistry. You'll discover how enzymes regulate chemical reactions and how they work within the human body. Our instructors will teach you about enzyme interactions and show you how the environment affects individual enzymes. The mystery of how enzymes manage to stay unaltered throughout complicated biochemical processes will also be revealed in these lessons. As you learn more about how enzymes work and function, you'll begin to better understand what job they hold within the body. You'll also grasp why enzymes are able to do their jobs so well. By the end of this chapter, you'll have studied concepts that include:
- The general function of enzymes
- Environmental effects on enzymes
- How enzymes lower the activation energy of a reaction
- Molecules that can negatively affect enzymes
|Function of Enzymes: Substrate, Active Site & Activation Energy||Explore the general function of enzymes and how they affect the energy of a reaction.|
|Function of Enzymes: Environmental Effects||Discover how the environment of cells can affect enzymes.|
|Coenzymes, Cofactors & Prosthetic Groups: Function and Interactions||Study how enzymes interact with coenzymes, cofactors and prosthetic groups.|
|Enzymatic Reactions: Inhibition and Regulation||Learn how enzymes can be inhibited or regulated by molecules.|
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.
