Cellular Respiration

Cellular Respiration:
Is the process by which cells obtain energy from glucose.

Stage #1:
In the cytoplasm glucose is broken down into smaller molecules

Stage #2:
In the mitochondria, the smaller molecules combine with oxygen to produce water and carbon dioxide

Respiration
“Breathing” this is the action to moving air in and out o your livings. Breaking brings oxygen, witch really necessary of the cellular respiration in your lungs

Photosynthesis vs Cellular respiration
In the photosynthesis, Carbon dioxide and water are used to produce sugar and oxygen; in the cellular repiration Sugar and oxygen are used to produce carbon dioxide and water.

Anaerobic respiration.
Some cells are able to obtain energy from food without using oxygen this cells obtend their energy though fermentation.The fermentation provides energy from cells without using oxygen.

Types of fermentation:
#1 Alcoholic fermentation: Occurs when yeast and some other single-called organisms break down sugars. This process is some times called alcoholic fermentation, because some one of the products is the alcohol. The others products are carbon dioxide and smalls amount of energy.

#2 Lactic acid fermentation: This take place in your muscle when the cells used up the oxygen faster that it Could be replaced, because your cells lacked oxygen, fermentations occurred and supplied the oxygen. When lactic acid builds up you feed a painful sensation in your muscles.
