Question

Please answer 9 and 10:

9. Aerobic respiration produces 30 molecules of ATP per molecule of glucose that is oxidized. What is the percentage efficiency of aerobic respiration? AGº for the hydrolysis of atp = -31 kJ/mol a) b) 25% c) 32% d) 41% e) 88% 10. A mutant lab rat was running on a treadmill in the gym. The rat's treadmill was coupled to a pulley which raised a 200g weight 1.5 m high. At the same time, the animal lost 5 J as heat. What was its change in internal energy (in kJ)? a) -8 ) b)-5) c) d) +29.5J e) +300)

Answer 1

Number of ATP molecule = 30 Ano for hydrolyus of ATP = - 31 kJ/mide Total energy = 30x 3) = 930 kJJwall Energy of glucose = 2805 kJ / wall Efficiency of Arsobic Desfidaton = 930 X100 = 33.16% - Answer © 324 2805 A Q =AUW W=ugh= = Q = -55 0.2kg x 9.8 m/s2 x 15m 2.943 AU = AQ-W = -5J - 2.943 - - 7.945 Answer @-85
