<u>Aerobic </u><u>respiration </u>:- Aerobic respiration is process of respiration in which complete oxidation of glucose takes place in the presence of oxygen
<u>That </u><u>is</u><u>, </u>
<u>Aerobic </u><u>respiration </u><u>is </u><u>takes </u><u>place </u><u>in </u><u>four </u><u>stages </u><u>:</u><u>-</u>
- <u>Glycolysis</u>
- <u>The </u><u>link </u><u>reaction </u>
- <u>The </u><u>Krebs </u><u>cycle </u>
- <u>Oxidative </u><u>phosphorylation </u>
In aerobic respiration, Glucose with 6 carbon atoms broken into 2 pyruvic acid each with 3 carbon atom and produces water + CO2 + energy.
<h3><u>Whereas</u><u>, </u></h3>
<u>Anaerobic </u><u>respiration </u>:- is the process of respiration in which incomplete oxidation of glucose takes place in the absence of oxygen
The end products of glucose in anaerobic respiration is
- <u>In </u><u>human </u><u>muscles</u><u>, </u><u> </u><u>Lactic </u><u>acid </u><u>+</u><u> </u><u>Energy </u>
- <u>In </u><u>yeast</u><u>, </u><u>Ethanol </u><u>+</u><u> </u><u>CO2</u><u> </u><u>+</u><u> </u><u>Energy </u>
<u>Hence</u><u>, </u><u>Option </u><u>D </u><u>is </u><u>the </u><u>correct </u><u>answer</u><u>.</u>
