Do we need to know about effect of cyanide on respiration for AQA A level Biology?

Hello,The exact specification can be found here http://filestore.aqa.org.uk/resources/biology/specifications/AQA-7401-7402-SP-2015.PDFRespiration is under section 3.5 Energy Transfer in OrganismsAlways a great idea to read through the specification yourself so you know exactly what is required of you (hence why I’m giving you the link but not the direct answer :)).Hope this helps,All the best,Matt

Hi Simon99, I completed my A Level Biology in 2016 and I found that although it is a good idea to learn about and understand the effects of cyanide on respiration in order to deal with the application part of the exam, it is not one of the main principles so it is best to concentrate on other aspects of the course.  As long as you can briefly outline the effects, you will be absolutely fine! Good luck!

Hi,The effect of Cyanide on (electron transport chain) is on the specification so it's a good idea to learn this. Always refer to how Cyanide prevents oxygen from binding to the final molecule in the ETC.Hope it helps
