A few days ago some friends asked me to help them with medical biochemistry. I obliged. On the topic of Biological Oxidation, they were having difficulty in grasping the concept of ATP Synthetase and how it generates energy (ATP). Basically ATP Synthetase is a molecular motor that is present in our dear cute mitochondria, when a force (H+ ions) rotates this motor, ATP is generated. ATP Synthetase is the smallest molecular rotary motor known.
You can see ATP Synthetase as a dynamo on your bicycle. When you pedal and the wheel rotates, the dynamo generates energy to light up the lamp.
I thought about making a model to help them understand. Googled but to no avail. Then to help them understand the concept I made this little widget. (Video is here)
I just want to leave this idea here as a potential project for someone or as a teaching aid. I hope it helps you. This can be used to demonstrate a lot of things; Like power generation by electric companies, back motor effect, Lenz law, turbines, ATP synthetase. Improvise!
