An experiment was conducted to investigate how temperature affects cellular respiration. the results are shown above. at what temperature do you predict the production of atp is greatest? a) the production of atp is greatest at 4o c as indicated by the use of co2 in the krebs cycle. b) the production of atp is greatest at 4o c as indicated by the consumption of o2 in the krebs cycle. c) the production of atp is greatest at 50o c as indicated by the production of co2 in the krebs cycle. d) the production of atp is greatest at 30o c because this is closest to human body temperature, the optimal temperature for enzyme function.
