The idea behind this animation is to help students think and learn about the process of Oxidative Phosphorylation. That is why the video doesn’t have any explanation. We, in the classroom (General biology, biochemistry, microbiology and others), study cellular respiration and watch the video. Unfortunately, many students will search the internet to get the “correct explanation” rather that study and think as an attempt to get an A in the assignment. So, explanations like this do not really help the educational system not only because they are not precise (many mistakes and misinterpretations can be found) but also because it encourages students to cheat in their assignments. Wouldn’t be better to ask people to study rather than tell them what they are watching?
