8.1 Metabolism

BioKnowledgy 8.1 Metabolism (AHL) from Chris Paine.

IB 8.1 – Metabolism, a 12m video lesson from Dan Rott:

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.

IB 2.8 & 8.2 Cell Respiration Part 1, a 12m video lesson from Dan Rott and IB 2.8 & 8.2 – Respiration Part 2 (7m).

3 video lessons from Alex Lee: Electron Tomography of Mitochondria (2m 33s); Phosphorylation (4m 13s) and Chemiosmotic Theory Paradigm Shift (3m 53s)

8.1 Cell Respiration essay qus

Paul Andersen covers the processes of aerobic and anaerobic Cellular Respiration in a 14m 14s tutorial and here is Hank Green’s Crash Course Biology #7: ATP & Respiration:

An excellent 6m overview of Cellular Respiration (Glycolysis, Krebs cycle, Electron Transport).

GLYCOLYSIS

A fantastic animated tutorial from McGraw Hill Education on how glycolysis works. Wiley also have an Interactive Animation  – just click on ‘Glycolysis

Steps of Glycolysis Reactions Explained in 5 minutes and in more detail than we need but it is very good. and here Mr W sings the Glycolysis! rap. Glycolysis Pathway Made Simple !! a 6m biochemistry lecture.

KREB’S (TCA) CYCLE

Here are some fantastic animated tutorials from McGraw Hill Education – how the Krebs cycle works. Wiley also have an Interactive Animation  – just click on ‘Citric Acid Cycle’.

Mr W sings the Kreb’s! rap. A very detailed lesson on HOW TO LEARN KREB’S CYCLE in 17m.

ETC, CHEMIOSMOSIS & ATP SYNTHASE

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

Here are some fantastic animated tutorials from McGraw Hill Education – how NAD+ works, the ETC & ATP synthase & proton pump & ATP synthase. Wiley also have an Interactive Animation  – just click on ‘Oxidative Phosphorylation’.

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

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:

Also IB 2.9 & 8.3 – Photosynthesis Part 1: Introduction to photosynthesis including ways to measure the rate and limiting factors of photosynthesis in 10m from Dan Rott. Or here is Photosynthesis part 1 of a series of tutorials, specific to IB Biology from Alex Lee.

Click on ‘Photosynthesis’ to see a detailed Interactive Animation from Wiley that covers all the reactions of Photosynthesis.

LIGHT DEPENDENT REACTIONS

Two fantastic animated tutorials from McGraw Hill Education – photosynthesis electron transport and  photophosporylation (cyclic & non-cyclic) – both are a bit more detailed than we need but they’re good.

This animation also shows how PSII and PSI reduce NADP: here.

This short, simple animation is a good summary of photosynthetic electron transport. as is this one from Biology 231.

Photosynthesis – Light-dependent Stage, an 8m video from Mr Exham or here is IB 2.9 & 8.3 – Photosynthesis Part 2: LDR in 9m from Dan Rott.

Mr W sings Photosynthesis – the LDR.

LIGHT INDEPENDENT REACTIONS (CALVIN CYCLE)

The Calvin cycle – a fantastic animated tutorial from McGraw Hill Education.

And here’s an animated, narrated tutorial on harvesting light – PSI & PSII in photosynthesisfrom Sinauer Associates.

Photosynthesis – Light-independent stage, a 5m video from Mr Exham, and here is a 5m TED-Ed lesson: Nature’s smallest factory: The Calvin cycle and this is IB 2.9 & 8.3 Photosynthesis Part 3: LIR in 11m from Dan Rott.

Mr W sings Photosynthesis – the LIR.

CALVIN’S EXPERIMENT

BioNInja has a great summary of the lollipop experiment, including a nice animation.

The Calvin Experiments – an animation that takes you through the 3 techniques he used to investigate the LIR.

Calvin’s Experiments (2016) IB Biology, a 10m video from Alex Lee.
