Keep it simple people…

Despite what you may think, the stuff we’ve covered so far in respiration is actually pretty straightforward. Just as we found out that our original formula for respiration (glucose + oxygen…) is hiding a wealth of sub-reactions that aren’t shown, the simple pathways of glycolysis and Krebs cycle have many steps that don’t need to concern us. If you want to look at them in more depth then fire away. Anyone considering following a biochemical course may wish to poke around further.

It is one of the areas of A2 that can be remembered by rote, however we have spent time trying to get an overview that will make understanding it a lot easier. Even so, you will forget most of this over the summer break, so anything you are not sure on now is the time to find out.

A few links that may be of help.

Youtube is also pretty good for videos, have a look if you can spare the time between looking at clips of dogs falling over and things that are ‘the funniest thing EVER’, which of course, they never are.
