Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
<u>Aerobic Respiration</u>
Occurs in the presence of free oxygen.
Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
Respiration occurs in the mitochondria.
Takes place in two steps or stages: Krebs cycle and electron transporter chain.
Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.
<u>Anaerobic Respiration </u>
Occurs in the absence of free oxygen
Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
Lactic fermentation produces lactic acid and 2 ATP
Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
The whole anaerobic process occurs outside the mitochondria.
Despite high temperatures should be melting the metals in the inner core, the extreme pressure keeps the earth's inner core in a sold phase. The solid metals make the earth's core very dense, at about 17 g/cm³
