1NADH=3ATP... so...in the 1st one...its written 2NADH=4ATP...bt..it should b 6 instead of 4ATP..thus i think it should b 38

I found it weird too upon first glance. But after a bit of thinking, it does make sense.

From glycolysis to the electron transport chain. each of these reactions is catalysed by specific enzymes. And so for respiration to take place, you need the enzymes to work as well!

And thus the higher the temperature the higher the rate of respiration because the kinetic energy of enzyme and substrate molecules increase, thereby increasing the concentration of E-S complexes.
