In the anaerobic respiration:
O2 is given out.
CO2 is given out.
CO2 is taken in.
O2 is taken in.
CO2 is given out in both aerobic and anaerobic respiration. Anaerobic respiration is a type of respiration that does not use oxygen.
Respiration in insects is called direct because
(a) the cells exchange O2/CO2 directly with the air in the tubes
(b) the tissues exchange O2/CO2 directly with the air in the tubes
(c) the tissues exchange O2/CO2 directly with the air outside through body surface
(d) tracheal tubes exchange O2/CO2 directly with the haemocoel which then exchange with tissues
For completion of respiration process, write the given steps in sequential manner.
(a) Diffusion of gases (O2 and CO2) across alveolar membrane.
(b) Transport of gases by blood.
(c) Utilisation of O2 by the cells for catabolic reactions and resultant release of CO2.
(d) Pulmonary ventilation by which atmospheric air is drawn in and CO2 rich alveolar air is released out.
(e) Diffusion of O2 and CO2 between blood and tissues.~
