Question 13
Which of the following is most appropriate for aerobic respiration?
(a) Glucosemitochondria−−−−−−−−→Pyruvatecytoplasm−−−−−−→CO2+H2O+Energy
(b) Glucosecytoplasm−−−−−−→Pyruvatemitochondria−−−−−−−−→CO2+H2O+Energy
(c) Glucosecytoplasm−−−−−−→Pyruvate+Energymitochondria−−−−−−−−→CO2+H2O
(d) Glucosecytoplasm−−−−−−→Pyruvate+Energymitochondria−−−−−−−−→CO2+H2O+Energy
(d) Glucosecytoplasm−−−−−−→Pyruvate+Energymitochondria−−−−−−−−→CO2+H2O+Energy
Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. The word aerobic means, in air, but it is the oxygen in the air which is necessary for aerobic respiration.
