About This Chapter
Chemical and Cellular Biology - Chapter Summary
This chapter covers basic elements of chemical and cellular biology that are essential for understanding how an organism functions. You'll cover some of the following topics:
- Identifying atoms and molecules, and their differences
- How chemical bonds connects different elements
- What makes up the cell
1. What are Atoms & Molecules? - Definition & Differences
There are lots of terms in chemistry that can be easy to mix up: atoms, molecules, compounds, mixtures, and more. In this lesson, we'll go through some of the basics of atoms and molecules, and define all of the important terms you need to know.
2. Overview of Chemical Bonds
Learn about the most common kinds of chemical bonds: ionic, covalent, polar covalent, and metallic. Discover how they form and why they hold together. Take a quiz and see how much knowledge you've held onto.
3. Organic Molecules: Functional Groups, Monomers & Polymers
Though life on Earth is incredibly diverse, all of it is built upon the same basic molecular structures. In this lesson, we'll look the basic building blocks of life and see how functional groups, monomers and polymers build up organic molecules.
4. ATP: Definition & Molecules
ATP is the molecule that fuels life. It is where our cells get the energy needed to perform their tasks. This lesson will define ATP, explain its structure, and briefly outline how it works.
5. What is a Cell Membrane? - Definition, Location & Facts
In this lesson, we'll discuss what a cell membrane is and its location. We'll also examine the cell membrane's functions, its components and structure, and its characteristics.
6. The Cell: Structure & Function
The cell is a small, but complex structure. Take a look inside the outer plasma membrane of a cell and discover the functions of some common cellular components, including the nucleus, endoplasmic reticulum, Golgi apparatus and mitochondria, in this lesson.
