OK, here are some more animations:

Step-through animation – from John Burrell at Patana

Respiration is not breathing! – Tim and Moby (Brainpop)

Good tutorial with questions – University of Wisconsin

Simple overview – Herriot Watt

Flash Overview – UC Davis biosciences

Windows Media overview (very flashy, above HL) – Virtual Cell Animation Collection

Stage-specific animations after the jump (glycolysis, Kreb’s cycle and ETC, oxidative phosphorylation)

Glycolysis:

Very advanced (but you can isolate the stages of phosphorylation, lysis, oxidation and ATP formation) – from Trinity College Dublin

Another complex one – John Kyrk

Krebs Cycle & ETC:

Basic step-by-step – NSTA Sci Links

Citric Acid Cycle – Essential Biochemistry

Another one from John Kyrk

Oxidative Phosphorylation:

Brilliantly simple ATP synthase animation – St Olaf college

.. and another one – NSTA

3D ATP synthase (right click to save Quicktime .mov) – University of Connecticut

Basic enough – McGraw Hill

Good (jump straight to ‘make ATP’) – University of Connecticut

Step-by-step tutorial – North Harris College

Complete step-by-step – Purdue

–

And here’s a video of ATP Synthase – the cellular turbine!

Practice Questions:

Metabolism problem set – University of Arizona

Musical Interludes:

“Bacteria ate up all the methane from the Deepwater Horizon oil spill” – can you explain the relevance of this story to this topic?
