Okay how many marks was question 6, the skeletal one, and the lung blood miligrams shi**
Original post by watercolour
i think i did alright in that.
what the **** was up with skeletal and lung blood milligrams and ****?
i cant even remember the question but i mentioned that aerobic respiration used up oxygen that the blood supplied via haemoglobin so the concentration would be higher in the blood cells leaving the lungs as they hadn't been distributed to the cells.. **** me. question 6 was ****.



I put something like oxygen diffuses out of capillaries into the skeletal muscle cells, then it is used to make energy in the mitochondria.
and that there is no source of oxygen in the muscles.
