About This Chapter
HiSET Science: Enzymatic Biochemistry - Chapter Summary
Get ready for the HiSET Science subtest by using the the effective lessons in this chapter to become familiar with enzymatic biochemistry concepts. The content will prepare you for questions about:
- Functions of enzymes
- Environmental effects on enzyme functioning
- Cofactors, coenzymes and prosthetic groups
- Enzyme regulation and inhibition
The lessons are in both video and text formats so you can choose whichever method works best for you. A practice quiz is available with each of the lessons to give you feedback bit-by-bit through the chapter.
Objectives of the HiSET Science: Enzymatic Biochemistry Chapter
The HiSET Science subtest evaluates your knowledge of various areas of science, including chemistry and biology. The subtest has a total of 50 multiple-choice questions; 50% of the questions are on the life sciences, which may include questions related to the topics covered in this chapter. You'll find that the majority of the questions include content dealing with scientific investigations. The time limit for completing the subtest has been set at 80 minutes. You'll be ready for any questions on enzymatic biochemistry after you're done studying these engaging lessons.
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.
