What is the difference between aerobic and anaerobic respiration? Are there differences in the energetic yields? Explain?Explanation / Answer
18. In aerobic respiration, a glucose molecule undergo complete oxidation and produce H2O & CO2. In addition to this it can produce nearly 32 ATP equivalents. Where as in anarobic respiration, a glucose molecule undergo partial oxidation and produce Lactic acid or Alcahol. In anarobic respiration, each glucose molecule only produce 2 ATPs. Anarobic respiration is also called as Fermentation
16. Metabolism is the total biochemical processes takes place in the living system. It is categorised into two types. Those are 1. Anabolism: It is a construction process in which simple molecules converted into complex molecules. Eg. Fatty acid synthesis, Glycogenesis etc. It utilizes energy. So it is active process, Nonspontanious process or Endergonic process. 2. Catabolism: It is a breakdown process in which complex molecules converted into simple molecules. Eg. Beta oxidation of Fatty Acids, Glycolysis etc. It releases energy. So it is passive process, spontanious process or Exergonic process.
15. During Bacterial growth in Batch type culture system, 4 different phases we can observe. Those are 1. Lag phase: Bacteria adopt to the media; 2. Log or Exponential: Rapid division of bacteria takes place and increase their number. It gives synchronus culture; 3. Stationary phase: Here death rate and growth rates are equal. 4. Decline phase: Death rate exceeds the growth
13. Mesophyles: Grow at moderate temperatures
Thermophyles: Grow at Extream temperatures
Psychrophyles: Grow at ultra low temperatures
