Concept Explanation
 

Aerobic Respiration

Aerobic respiration: The complete oxidation of food yielding carbon dioxide, water and energy in the presence of oxygen is called aerobic respiration. This respiration starts in the cytoplasm (glycolysis) and continues in the mitochondria (Kreb's cycle) of the cell. The products of this reaction include: ATP, carbon dioxide and water.

The number of molecules of ATP formed by each glucose molecule during aerobic respiration is 38. Hence, the energy made available is much greater than in the case of anaerobic respiration.

In the process, energy is produced. This energy is used to drive cellular processes that are endothermic (processes that absorb energy). steps take place during aerobic respiration are:

In Cytoplasm (Glycolysis)

                                 Glucose:(6;Carbon)xrightarrow[In;Cytoplasm]{Glycolysis}Pyruvic ;Acid; (3;Carbon)

In Mitochondria (Kreb cycle )

                               Pyruvic: Acidxrightarrow[In;mitochondria;presence;of;oxygen]{Krebs;Cycle} CO_2+H_2O+38ATP
