1. 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.
2. Structure and Function of Carbohydrates
Carbohydrates are found in many foods that we eat and may be found as sugars, starches, or fiber. Learn more about these three distinct types of carbohydrates, and how they are distinguished through their chemical structures in this lesson.
3. How Amino Acids Form Protein
Amino acids are the building blocks of proteins. Learn about the basic structure of an amino acid and how the molecules bond together through peptide bonds using a process called a dehydration synthesis reaction.
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. Structure and Function of Lipids
Molecules called lipids have long hydrocarbon chains that determine the way they act. They can be fats, oils, or hormones, and even exist in our cell membranes. Learn more about the chemical structure and biological function of various lipids in this lesson.
6. DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds
In this lesson, you'll discover what nucleotides look like and how they come together to form polynucleotides. We'll also explore nucleic acids and focus on DNA in particular.
7. Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)
In this lesson, you'll explore RNA structure and learn the central dogma of molecular biology. Along the way, you'll meet the three types of RNA and see how the cell uses them most effectively.
8. Genomic DNA Analysis
Your genes are what make you who you are, but they also make you a human. Studying genes and genomes allows scientists to better understand not only our own species, but how we are related to other species in the world as well.
9. DNA Cloning: Definition and Process
DNA cloning is used for a variety of purposes, but how does it work? In this video lesson, you will learn about the process of cloning DNA, as well as see examples of how cloning is used in science, medicine, and consumer products.
10. Cellular Respiration: Energy Transfer in Cells
Watch this short video to learn the basics about converting organic compounds into ATP, also known as cellular respiration. We'll look at an overview of the process.
11. Anabolism and Catabolism: Definitions & Examples
Metabolism breaks down large molecules like food into usable energy. This energy drives bodily processes critical to survival. In this video lesson, you will learn about the two forms of metabolism that break down and build up molecules and see examples of each.
12. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle
Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.
