About Cellular Respiration: The Krebs Cycle Virtual Lab Simulation

This short, targeted simulation is adapted from the full-length “Cellular Respiration” simulation.

What happens to the two pyruvate molecules after glycolysis? In this simulation, you will further your understanding of cellular respiration by taking a closer look at mitochondria and the second stage of aerobic respiration: the Krebs cycle, also known as the citric acid cycle. The council has hired you to pass on your knowledge of metabolism to the basketball team to help them understand the science behind exercise and metabolism, so they can improve their training and maintain stamina during their game.

Evaluate The Krebs Cycle

Observe how the product of the first stage of glycolysis, the pyruvate molecule, is significant for the next step of aerobic respiration, the Krebs cycle. Getting up close and personal with a giant sized mitochondrion, understand the relation of the two processes by inserting the pyruvate molecule in the matrix. You will evaluate the stages of the Krebs cycle by completing each step through an engaging and interactive activity, exploring the different components and reactions that take place.

Review your Knowledge

Throughout the simulation engaging quiz questions will be asked to reinforce your knowledge of the Krebs cycle, to further your learning of aerobic respiration and metabolism. To accompany the quiz questions there are relevant theory pages and informative diagrams to aid your learning.

Pass on your knowledge

Having learned about the second stage of aerobic respiration you are able to pass on your knowledge to the basketball players, so they too can understand the science behind metabolism and exercise and improve their training.
