8.1 Metabolism

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/straintransition state (activation energy), proximity and orientation, chemical interaction, biochemical pathway & allosteric enzyme.

Here are some fantastic animated tutorials from McGraw Hill Education – how enzymes worka 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.

8.2 Cell Respiration

BioKnowledgy 8.2 Cell respiration AHL from Chris Paine.

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

8.1 Cell Respiration essay qus

Paul Andersen covers the processes of aerobic and anaerobic Cellular Respiration in a 14m 14s tutorial.

Short, simple animations to show mitochondrial electron transport, ATP synthase & ATP synthase mechanism

Here are some fantastic animated tutorials from McGraw Hill Education – how glycolysis works, how NAD+ works, how the Krebs cycle works, the ETC & ATP synthase & proton pump & ATP synthase.

Wiley have a number of Interactive Animations about Cell Respiration that take you through it step-by-step; just click on ‘Glycolysis’ or ‘Citric Acid Cycle’ or ‘Oxidative Phosphorylation’ in the link.

Another animated tutorial of the ETS is here.

How Cells Obtain Energy a 14m 2s vid from 2004:

Powering the Cell: Mitochondria, a 2m 9s visual treat from Harvard University; and here is part of it with narration.

Mr W sings the Glycolysis! rap and then the Kreb’s! rap.

8.3 Photosynthesis

BioKnowledgy 8.3 Photosynthesis AHL from Chris Paine.

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

8.2 Photosynthesis essay qus

Paul Andersen explains the process of Photosynthesis in a 12m 27s tutorial:

Or here is part 1 of a series of tutorials, specific to IB Biology.

A short, simple animation to show photosynthetic electron transport and here is an animated video that explains the LDR.

Click on ‘Photosynthesis’ to see an Interactive Animation from Wiley or here are some fantastic animated tutorials from McGraw Hill Education – Photophosporylation (cyclic & non-cyclic) – a bit more detailed than we need but its good, photosynthesis electron transport & ATP synthesis &  the Calvin cycle.

Finally, here’s an animated, narrated tutorial on harvesting light – PSI & PSII in photosynthesis – from Sinauer Associates.

Mr W sings Photosynthesis – the LDR and the LIR.
