Prokaryotic and Eukaryotic Cells

What you will learn The two types of cells: prokaryotic and eukaryotic How eukaryotic cells differ in structure from prokaryotic cells [Figure 1] How many different types of cells are there? There are many different types of cells. For example, in you there are blood cells and skin cells and bone cells, and even bacteria. Here we have drawings of bacteria and animal cells. Can you […]

Parts of the Cell

Purpose We will study How and when cells were discovered The cell theory How diverse are cells What parts are common among all living cells so I can  to  by . [print-me alt=”Click icon to print this section” target=”h2,p”/] Vocabulary one two three Resources one two Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit […]

Acids and Bases

What you will learn The properties of acids and bases How acids and bases are important in living organisms [Figure 1] Acids and bases. Why are these important in biology? It comes back to a number of biological processes. For example, enzymes work best at specific levels of acids or bases. Take your stomach, a very acidic environment. The […]

Water and Life

What you will learn The distribution of water on Earth The chemical structure and properties of water How water is important for all life processes [Figure 1] Dihydrogen oxide, or dihydrogen monoxide. Does this chemical sound dangerous? Another name for this compound is…water. Water can create some absolutely beautiful sights. Iguassu Falls is the largest series of waterfalls […]

Enzyme Function

What will you learn How do enzymes work What is the role of the active site of an enzyme Factors that affect enzyme activity [Figure 1] Do cells have one enzyme with lots of functions, or many enzymes, each with just one function? Enzymes. Vital proteins necessary for life. So how do enzymes work? How do they catalyze just one specific biochemical reaction? […]

Enzymes

What you will learn How enzymes catalyze biochemical reactions Importance of enzymes [Figure 1] What is a biological catalyst? This super fast train can obviously reach great speeds. And there’s a lot of technology that helps this train go fast. Speaking of helping things go fast brings us to enzymes. Life could not exist without enzymes. […]

Types of Biochemical Reactions

What you will learn Biochemical reactions and their role in metabolism The types of biochemical reactions [Figure 1] What do you get when you cross biology and chemistry? Hummingbirds, with their tiny bodies and high levels of activity, have the highest metabolic rates of any animal — roughly a dozen times that of a pigeon and a hundred times […]

Energy and Biochemical Reactions

What will you learn How energy is involved in a chemical reaction Endothermic and exothermic reactions [Figure 1] What is energy? Where does your energy come from? Can energy be recycled? This team of ants is breaking down a dead tree. A classic example of teamwork. And all that work takes energy. In fact, each chemical reaction – the […]

Biochemical Reactions

What you will learn Chemical reactions and biochemical reactions Reactants and products in a chemical reaction How to write a chemical equation Conservation of matter in chemical reactions [Figure 1] Understanding chemistry is essential to fully understand biology. Why? A general understanding of chemistry is necessary to understand biology. Essentially, our cells are just thousands of chemicals — made of elements like carbon, hydrogen, […]

Nucleic Acids

What you will learn Nucleic acids and their structure Role of nucleic acids [Figure 1] You may have heard that something is “encoded in your DNA.” What does that mean? Nucleic acids. Essentially the “instructions” or the “code” of life. Deoxyribonucleic acid, or DNA, carries the unique code to make the proteins that give you your traits. Half […]
