Connecting Concepts: Cell Biology/Chemiosmosis

This tutorial/simulation consists of three topics. In topic 1, students look at the components of chemiosmosis in the bacterium Paracoccus denitrificans in which they step through animations of electron transport, proton gradient, and ATP synthase, learning the components involved in each. In topic 2, students construct chemiosmosis pathways in mitochondria and chloroplasts. Students will: 1) select the correct components (electron donor and acceptor, ETC, ATP synthase) and place them in the appropriate subcellular location ; 2) apply concepts about redox reactions, concentration gradients, and energetics to explain how chemiosmosis fits in a cell’s overall metabolism; and 3)summarize properties of chemiosmosis in organelles and Parcoccus denitificans. In topic 3, students follow the... Show More

An excellent interactive exercise that investigates the concept of chemiosmosis. Students are required to draw conclusions from information and data provided. This is a topic that students find very difficult. Very well organized and well written.
