Do we need to know about urobillins for tomorrow??

As this is because urine contains urobilins, these are made through bthe break down of haemoglobin

Why is there still some Urea in the blood after it has left the kidneys?

"Evaluate the the effectiveness of sport drinks" would surely be too small of a topic for a six marker, right? I know MYGCSESCIENCE done a rather long video on it but a lot of the areas he talked about are not on the specification. If they were to give a 6 mark question on that topic, it would have to be a question with a large text attached to it - similar to that of the C2 January 2013 six mark question.

We need to know that????????????

Not to be rude, but can you guys not bring BS that's not in the spec up and create unecessary stress please. Much appreciated, no you don't need to know what 'urobillins' are they are not in any textbook or past paper..

Have a high number of mitochondria for active transport, large surface area and thin walls for diffusion...

What do sport drinks contain?
