How Cells Harvest Energy

The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...

This four-page worksheet queries young biologists about the process of metabolism in the human body. They describe types of energy, laws of thermodynamics, and chemical reactions related to the processing of energy. Plenty of space is...

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

Sketch the ATP cycle, label a diagram of the catalytic enzyme cycle, and write short answers to questions about the enzymes involved in human metabolism. This worksheet puts AP biology learners to the test. Assign it as a review homework...

Beginning biologists demonstrate their grasp on cellular respiration, photosynthesis, and energy flow though ecosystems when completing this worksheet. Fifteen multiple choice and short answer questions test their knowledge. Because of...

Energize biologists with colorful images in an activity that captivates the imagination while demystifying the subject of cellular respiration. Participants build comprehension skills and access core content knowledge by analyzing text...

Salman Khan is very enthusiastic about the topic of cellular respiration! He provides an interesting presentation of the respiration process. Expect to learn about the basic stages of respiration, how it works in the human body, and the...

Explain the two-step process of photosynthesis to your high school biologists with a focus on the Calvin cycle. Using adorable animation, a video likens the cycle to a tiny, sustainable factory. Even though the enzyme-bird rubisco and...

Free energy, get your free energy here! Learners see that all organisms require free energy, which comes from the sun. The lesson explains the first two laws of thermodynamics and then analyzes metabolism, via glycolysis, on a very...

ATP — it's everywhere! The video describes aerobic and anaerobic respiration, how the processes of glycolysis, the Kreb cycle, and the Electron Transport Chain work inside the cells to produce ATP, and ends with a discussion about lactic...
