About This Chapter
How it works:
- Identify which concepts are covered on your enzymatic biochemistry homework.
- Find videos on those topics within this chapter.
- Watch fun videos, pausing and reviewing as needed.
- Complete sample problems and get instant feedback.
- Finish your enzymatic biochemistry homework with ease!
Topics from your homework you'll be able to complete:
- Enzyme functions
- Enzymatic reactions
- Functions and interactions of coenzymes, cofactors and prosthetic groups
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.
