This animation demonstrates two full cycles of electron donation. It also illustrates the various components involved in the electron transport chain including NADH dehydrogenase, cytochrome b-c1, cytochrome oxidase, ATP synthase, ubiquinone, cytochrome c, NADH, electrons, hydrogen ions, molecular oxygen, water, ADP and Pi. The site is one animation form a larger archive of cellular processes from the Virtual Cell Animation Collection, Molecular & Cellular Biology Education Project at North Dakota State University.
Type of Material:
Flash movie animation.
This object could be used to augment a class presentation as a pre-class assignment, or as a review.
Web Browser with Flash plugin.
Identify Major Learning Goals:
No specific learning outcomes are listed
Target Student Population:
Advanced High school, lower level undergraduate.
Prerequisite Knowledge or Skills:
Overall knowledge of aerobic cellular respiration process.
Evaluation and Observation
Animation is clear and easy to follow.
Narration is appropriate for the information presented and matches the action in the animation.
Information is accurate.
There are a couple of pauses in the dialogue that may make the listener think there is a problem with the audio.
Potential Effectiveness as a Teaching Tool
Would work well as as an adjunct to classroom presentation.
Could be used as an assignment prior to class.
Will make a good review.
Students can play animation multiple times until they are comfortable that they can explain the process.
Introduces the main concepts without getting lost in too much detail.
Short enough to keep listeners attention, but long enough to introduce important components and concepts.
Some simplification done to make presentation clear
Student needs to know place of process in overall aerobic respiration
Animation stops before explaining ATP Synthase--that is a separate
Cartoon molecules with colored in spheres is a little ambiguous.
Providing a little more detail on the molecular structure would be helpful for students in Sophomore level course and above.
Ease of Use for Both Students and Faculty
Very easy to use.
Transcript of narration provided.
Video size is good, even for students with visual impairments.
Animation is short and would be better with ATP Synthase included.
Flash player required.
The size of the video (18 MB) could be an issue for users with poor internet bandwidth.
