About This Chapter
Washington EOC Biology Grade 10: Chemical Reactions in Cells - Chapter Summary
The Washington End-of-Course (EOC) Grade 10 Biology exam includes questions on chemical reactions in cells. You can prepare for these types of questions with the video lessons found in this chapter. Some of the topics you will learn about in the lessons include:
- Cellular production of energy through the breakdown of molecules
- Large molecules and the support of cell functions
- The function of enzymes
- Enzymatic reactions
- The environmental effects of enzymes
The resources in this chapter will help you prepare for content of the Washington EOC Exam related to cell reactions. Watching these video lessons and taking the practice quizzes will give you a greater advantage on test day.
1. How Cells Break Down Molecules for Energy
Large cells in our food are broken down by the digestive system, and converted into energy through cellular respiration. The food provides both energy and the building blocks to create new cells and repair the body. Learn about how we break down molecules into energy in this process.
2. How Large Molecules Support Cell Function
In this lesson, we will talk about the different types of large molecules and the ways that they are responsible for cell function. We will meet four broad categories of large biomolecules: nucleic acids, proteins, carbohydrates, and lipids. We will also learn about the building blocks that make up these biomolecules.
3. 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.
4. 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!
5. 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.
6. 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.
