Respiration question help pleaseWatch
Here’s the mark scheme
I understand the first point and the 2nd point
And I understand that less oxidative phosphorylation occurs. What I don’t understand is why no ATP is made . The first 2 redox reactions produce ATP so how come the only ATP produced will be from glycolysis ?
And another partially irrelevant question , the water produced by respiration , is it lost or can it be used / stay in the body for all its uses?
Q2: Any chemical or substance in the body has its levels in the body (and, more specifically, in every tissue/organ) determined by the overall balance of various (reversible) reactions/processes. Therefore, some of the water that is an end-product of respiration is breathed out as water vapour (the reason a mirror gets fogged up if you breathe out on it!!), some will be lost in sweat, particularly during physical exertion OR in hot weather [which is absent in UK!), and some might be used in various physiological processes in the body, e.g. as a component of blood or lymph, or as synovial fluid in a joint, etc (the same variable fate as any other water in the body e.g. that you drank last night during your clubbing (remember, beer is mostly water!) would face).
