- D(i), (ii) and (iii)
Correct answer
A. (i) and (ii)
Step-by-step solution
Respiration is part of the metabolic process where the nutrients are converted into useful energy for regular cell activities. It is in two mode depending on presence or absence of oxygen. Aerobic respiration is the one where oxygen is involved and anaerobic respiration is the process where oxygen is absent. One of the factor regulating rate of respiration is the temperature and the Q 10 temperature co-efficient for respiration in the range of 0 – 25 o C is 2, which means rate of respiration doubles for every 10 o
