8.1 Metabolism
8.1 metabolism from Bob Smullen
IB 8.1 – Metabolism, a 12m video lesson from Dan Rott:
Mr Bozeman describes Enzymes:
Enzyme Inhibition explained:
Here are some fantastic animated tutorials from McGraw Hill Education – how enzymes work, a biochemical pathway & feedback inhibition of biochemical pathways.
8.2 Cell Respiration
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.
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 is a fantastic animated tutorial from McGraw Hill Education – how the Krebs cycle works.
Mr W sings the Kreb’s! rap. A very detailed lesson on HOW TO LEARN KREB’S CYCLE in 17m.
ETC, CHEMIOSMOSIS & ATP SYNTHASE
Here are some fantastic animated tutorials from McGraw Hill Education – how NAD+ works, the ETC & ATP synthase & proton pump & ATP synthase.
Powering the Cell: Mitochondria, a 2m 9s visual treat from Harvard University; and here is part of it with narration. Mr W sings the ETC rap (badly!) and here is the ETC in a 7m video – more detail than you need but it is great!
Cellular Respiration (2.8. and 8.2 together):
IB Biology cellular respiration 2015.ppt from Bob Smullen
Key terms as flashcards from Quizlet (you also can test yourself in a number of ways):
8.3 Photosynthesis
8.3 photosynthesis from Bob Smullen
Find a video lesson on this sub-topic at Dan Rott videos.
McGraw Hill Photosynthesis tutorial and 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.
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.
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 photosynthesis – from 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.
Calvin’s Experiments (2016) IB Biology, a 10m video from Alex Lee.
