Hank explains another stage of cellular respiration, The Krebs Cycle (also known as the Citric Acid Cycle). He notes that the purpose of this stage is to generate energy and uses several examples to convey how this process is necessary in our daily lives.

Hank explains the Electron Transport Chain stage of cellular respiration. He notes that this stage is the "money maker" because it generates a lot more ATP than any other stage.

Beakman explains how leaves lose chlorophyll using a cartoon video. Then he explains the role of chlorophlyll in photosynthesis verbally. To further demonstrate, Beakman acts like the "chef" chlorophyll that provides food for the plant.

Hank explains in-depth the series of reactions that take place for a plant to produce food for itself, also known as photosynthesis. This video also explores the prerequisites (sunlight, carbon dioxide, and water) of these reactions. Key Words: Xylem, Stomata, Chlorophyll, Chloroplast, Thylakoid, Photoexcitation, Photosystem II, Electron Transport Chain, Cytochrome Complex, ATP 

By observing the chloroplasts in a leaf, the students learn that plants produce their own food and do not get it from another source. The students come to the conclusion that the chloroplasts use sunlight, air, and water to create sugar, which is used as energy for the plant.
