Aerobic Respiration :
is the process of producing cellular energy involving oxygen.Cells break down food in the mitochondria in a long, multistep process that produces
what it is
Mitochondria are organelles whose membranes are specialized for aerobic respiration. The matrix of the mitochondria is the site of Krebs Cycle reactions. The electron transport chain and most ATP synthesis
-
if no oxygen is taken in at the cellular level no ATP production, no muscle contraction After two minutes of exercise, the body works to supply muscles with oxygen. In the presence of oxygen, glucose is completely broken down into carbon dioxide and water.
Effects of exercise
-
Respiratory benefits of regular exercise: Exercise improves your lung capacity. Exercise increases the blood flow to your lungs, allowing the lungs to deliver more oxygen into the blood.
Fermentation
the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.
For example, fermentation is used for preservation in a process that produces lactic acid found in such sour foods as pickled cucumbers, kimchi, and yogurt, as well as for producing alcoholic beverages such as wine and beer.

Anaerobic Respiration
Anaerobic respiration is respiration using electron receptors other than molecular oxygen . Although oxygen is not the final electron.
