8.1 Metabolism

Leave a reply

BioKnowledgy 8.1 Metabolism (AHL) from Chris Paine.

Find a video lesson on this sub-topic at Dan Rott videos.

Activation Energy:

Mr Bozeman describes Enzymes:

Enzyme Inhibition explained:

Short, simple animations about enzymes to show conformational change/strain, transition state (activation energy), proximity and orientation, chemical interaction, biochemical pathway & allosteric enzyme.

Here are some fantastic animated tutorials from McGraw Hill Education – how enzymes work,  a biochemical pathway  &  feedback inhibition of biochemical pathways.
Wiley have a number of Interactive Animations about enzymes, just click on ‘Catalysis’ or ‘Enzyme Inhibition’ or ‘Enzyme Specificity’ in the link.

They also have ‘Introduction to Metabolism’ & click on ‘Metabolic Process Location’ to see an Interactive Animation which is a good review of metabolic processes in the human body.

A powerpoint from the OLD syllabus, but much is still relevant.

A fantastic animated tutorial from McGraw Hill Education on the Organs of Digestion & one on the action of Sucrase.

Mr Paul Andersen (from Bozeman High) details The Digestive System in a 9m 38s tutorial:

In Crash Course Biology #28 – The Digestive System, Hank takes us through the bowels of the human digestive system and explains why it’s all about surface area.
