Think of yeast cells. They barely survive at 10 °C, but they do get along in water and sugar, slowly. If you bring them up to their ideal temperature with a lot of food, they go into explosive growth and the solution starts aggressively bubbling. It's orders of magnitude more metabolic activity when it's warm. If you cool human cells down their metabolism and oxygen demands slow down in the same way.
(Not coincidentally, yeast's happy temperature is not too different from normal human body temperature. A lot of biochemical processes go their fastest around ~35 °C or so without the involved molecules breaking down, and the mammalian trick was to keep all our cells at a near-ideal point all the time. We're aggressively bubbling solutions of CO2 all the time, normally.)
