Question

The basal rate of consumption of O2 by a 70. kg human is about 16 mol of O2 per day. This O2 oxidizes food and is reduced to H2O, providing energy for the organism 4 Ht 4 e = 2 H20 O2 (a) To what current (in amperes C/s) does this respiration rate correspond? (Current is defined by the flow of electrons from food to O2.) 4.0 A (b) Compare your answer in part (a) with the current drawn by a refrigerator using 4.02 x 102 W at 111 V. Remember that power (in watts) work/s = E-I 4.0 Select- current than the refrigerator X (c) If the electrons flow from nicotinamide adenine dinucleotide (NADH) to O2, they experience a potential drop of 1.1 v. What is the power output (in watts) of our human friend? 4.0
