Hans Krebs – Cellular Respiration and the Discovery of the Krebs Cycle
Fact Sheet, Quiz & Interactive Exercises (PDF + H5P) 🔁🧬

This 45-minute resource introduces students in grades 10–12 to Hans Krebs – the scientist who uncovered one of the most important metabolic pathways in our cells: the citric acid cycle, also known as the Krebs cycle.

When teaching cellular respiration, many students can follow the basics of glucose breakdown and ATP production – but the details of what happens in the mitochondria often feel abstract. Krebs' discovery in the 1930s helped explain how cells extract energy efficiently from food molecules through a cycle of chemical reactions. It’s a key part of understanding aerobic respiration and metabolism.

To make this complex process more accessible, I’ve created a structured lesson that includes a short informational text, a fact sheet, quiz questions with answers, and a creative partner task. All materials are available in color and black-and-white, plus there’s a digital H5P version for interactive learning.

What’s included:

• A student-friendly text about Hans Krebs and the citric acid cycle

• A fact sheet to help visualize and summarize the steps of the cycle

• Quiz questions (with answer key) for quick review or comprehension checks

• A creative task where students develop and exchange their own questions in pairs

• Formats: Printable PDF and interactive H5P 💻

• Answer key included ✅

I’ve used this resource during our unit on cellular respiration, often right after glycolysis and before moving on to the electron transport chain. It’s especially helpful for students who benefit from breaking down complex processes into steps. The partner activity works well for revision or as preparation for assessments.
