Enzymes are a type of protein essential to life and necessary for many of the metabolic reactions that occur in the human body. Since these reactions occur at the molecular level within the body, students do not directly observe enzymes functioning. |
| Water as a Solvent: | The lesson is an activity introducing the versatility of water as a solvent. Students will initially predict the solubility of a substance by matching the substance with an appropriate solvent.

| ATP: The Fuel of Life: | The goal of this lesson is to introduce students who are interested in human biology and biochemistry to the subtleties of energy metabolism (typically not presented in standard biology and biochemistry textbooks) through the lens of ATP as the primary energy currency of the cell. Avoiding the details of the major pathways of energy production (such as glycolysis, the citric acid cycle, and oxidative phosphorylation), this lesson is focused exclusively on ATP, which is truly the fuel of life. Starting with the discovery and history of ATP, this lesson will walk the students through 8 segments (outlined below) interspersed by 7 in-class challenge questions and activities, to the final step of ATP production by the ATP synthase, an amazing molecular machine. A basic understanding of the components and subcellular organization (e.g. organelles, membranes, etc.) and chemical foundation (e.g. biomolecules, chemical equilibrium, biochemical energetics, etc.) of a eukaryotic cell is a desired prerequisite, but it is not a must. Through interactive in-class activities, this lesson is designed to spark the students' interest in biochemistry and human biology as a whole, but could serve as an introductory lesson to teaching advanced concepts of metabolism and bioenergetics in high school depending on the local science curriculum. No supplies or materials are needed. |

| MIT BLOSSOMS - Roots, Shoots, and Wood: | The topic of photosynthesis is a fundamental concept in biology, chemistry, and earth science. Educational studies have found that despite classroom presentations, most students retain their naïve idea that a plant's mass is mostly derived from the soil, and not from the air. To call students' attention to this misconception, at the beginning of this lesson we will provide a surprising experimental result so that students will confront their mental mistake. Next, we will help students better envision photosynthesis by modeling where the atoms come from in this important process that produces food for the planet. This lesson can be completed in 50-60 minutes, with the students working on in-class activities during 20-25 minutes of the lesson. As a prerequisite, students need an introductory lesson on photosynthesis, something that includes the overall chemical equation. If students have already studied the intracellular photosynthetic process in detail, this video can still be very helpful because students often miss the big picture about photosynthesis. Materials needed include red, white and black LEGO bricks (described in downloadable hand-out) or strips of red, white and black paper plus paper clips (directions provided in downloadable hand-out). In addition to class discussions, the major in-class activity of this video involves the students' modeling with LEGO® bricks or colored paper where the atoms come from in photosynthesis. |
| Cellular Respiration: | These animations show cell respiration as a big picture, and then go through the steps of cellular respiration: glycolysis, the Krebs cycle, and electron transport. Each animation is short and to the point. |
| Lipids: | Paul Anderson describes the lipids (of the fats). He explains how they are an important source of energy but are also required to cell membranes. He explains how the hydrocarbon tails in triglycerides contain energy available for life. He also explains how phospholipids construct, and cholesterol molecules main the cell membrane. |
| MIT BLOSSOMS - Methods for Protein Purification: | This Protein Purification
video lesson is intended to give students
some insight into the process and tools
that scientists and engineers use to
explore proteins. It is designed to
extend the knowledge of students who
are already somewhat sophisticated and
who have a good understanding of basic
biology. The question that motivates
this lesson is, "what makes two
cell types different?" and this
question is posed in several ways. Such
scientific reasoning raises the experimental
question: how could you study just a
subset of specialized proteins that
distinguish one cell type from another?
Two techniques useful in this regard
are considered in the lesson. This video
lesson will easily fit into a 50-minute
class period, and prerequisites include
a good understanding of cellular components
(DNA vs. Protein vs. lipid) and some
understanding of the physical features
of proteins (charge, size etc). The
simple cell model used here can be assembled
in any kind of container and with any
components of different solubility,
density, charge etc. In-class activities
during the video breaks include discussions,
careful observations, and the use of
a "very simple cell" model
to explore two techniques of protein
purification. Students and teachers
can spend additional time discussing
and exploring the question of "how
we know what we know" since this
lesson lends itself to the teaching
of the process of science as well. |

| Cellular Respiration: Kreb's Cycle: | This Khan Academy video describes how the pyruvate produced in glycolysis undergoes oxidation to produce Acetyl CoA. The video then explains what occurs when Acetyl CoA enters the Kreb's cycle and how NADH and FADH2 are produced. |
| Photosynthesis: The Light Reactions: | This Khan Academy tutorial explains in detail the process of the light reactions of photosynthesis including the importance of the thylakoid membrane and the products that are produced from this reaction. |
| Photosynthesis: The Calvin Cycle: | This Khan Academy tutorial explains how the by-products from the light reactions of photosynthesis are used to produce sugar molecules in the Calvin Cycle. |
| ATP: Adenosine Triphosphate: | This Khan Academy video explains how the molecule ATP stores the energy needed for biological systems within organisms. |
| Introduction to Cellular Respiration: | This Khan Academy video describes how energy is extracted from the glucose molecule to make ATP. Each biochemical pathway involved in cellular respiration is discussed. |
| How Glycolysis Works: | This animation shows the process of glycolysis. The reactants, products, and the basic functions of aerobic and anaerobic cellular respiration are identified. |
| ATP Synthesis During Photosynthesis: | Photosynthesis is often described as the reverse of cellular respiration. Respiration breaks down complex molecules to release energy that is used to make ATP. Photosynthesis takes energy from photons and uses it to build complex molecules. However both systems use an electron transport chain and associated proton pump and ATP synthase as a key part of the process. This tutorial will help you to understand the electron transport chain and ATP synthesis. |
| The Role of Vitamins in Human Nutrition: | This tutorial will help you to understand the role that vitamins play in human nutrition. Vitamins interact with enzymes to allow them to function more effectively. Though vitamins are not consumed in metabolism, they are vital for the process of metabolism to occur.
This challenging tutorial addresses the concept at a high level of complexity. |
| Cellular Respiration: | This tutorial reviews the process of cellular respiration which is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP). |
| The Simple Story of Photosynthesis and Food : | Photosynthesis is an essential part of the exchange between humans and plants. Amanda Ooten walks us through the process of photosynthesis, also discussing the relationship between photosynthesis and carbohydrates, starch, and fiber -- and how the air we breathe is related to the food we ingest. |
| How Polarity Makes Water Behave Strangely: | Water is both essential and unique. Many of its particular qualities stem from the fact that it consists of two hydrogen atoms and one oxygen, therefore creating an unequal sharing of electrons. From fish in frozen lakes to ice floating on water, Christina Kleinberg describes the effects of polarity. |
| Nature's Smallest Factory: The Calvin Cycle: | A hearty bowl of cereal gives you the energy to start your day, but how exactly did that energy make its way into your bowl? It all begins with photosynthesis, the process that converts the air we breathe into energizing glucose. Cathy Symington details the highly efficient second phase of photosynthesis -- called the Calvin cycle -- which converts carbon dioxide into sugar with some clever mix-and-match math. |
| Activation Energy-Kickstarting Chemical Reactions: | Chemical reactions are constantly happening in your body -- even at this very moment. But what catalyzes these important reactions? This short video explains how enzymes assist the process, while providing a light-hearted way to remember how activation energy works. |
