About This Chapter
TExES Life Science: Enzymes - Chapter Summary
You're likely to encounter questions about enzymes on the TExES Life Science test. If you're feeling like you need a refresher on the subject, we can help you with that. Our chapter on enzymes contains brief video lessons that will guide you through all the relevant essentials. The videos are brief and succinct because we know you need to be efficient about your time management. You can easily fit the videos into small breaks throughout your day or save them all to watch right before bed or first thing in the morning. While short, the video lessons are still thorough in their review of topics like:
- Enzyme function
- Role of coenzymes and cofactors
- Interactions of prosthetic groups
- Regulation and inhibition of enzymatic reactions
Each of the lessons is followed by a short multiple-choice quiz. Be sure to complete these so you know how well you're retaining the information. You can contact our expert instructors if you have any burning questions.
Objectives of the TExES Life Science: Enzymes Chapter
If you're pursuing teaching certification or endorsement in Texas, you'll need to take the TExES Life Science test and we'd love to help you prepare. The test is computer-administered and consists of 100 multiple-choice questions divided into six domains. The second domain, Cell Structure and Processes, accounts for about 20% of the exam. It will, among other things, test you on your ability to analyze how the function of biomolecules, including enzymes, is related to structure and shape. It will also explain the role of enzymes in synthesis and the degradation of biomolecules like DNA, carbohydrates, lipids, proteins, and more. We have purposely tried to correlate our chapter topics, that you can read about in the chapter summary, with these test objectives.
1. The Function of Enzymes
Have you ever used a drill to accelerate building something that only requires a screwdriver? It went a lot faster, didn't it? In this lesson, you'll learn how that drill is a lot like an enzyme.
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. 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.
