ii), iii), iv) only
iv) only ​

Answer 1

Answer:

(b)

Explanation:

Aerobic Anerobic Amount of energy is high and inconsistent in aerobic and low in Anaerobic

Answer 2

The correct combination of plots and justification is given by:

Plot A- Aerobic

Plot B - Anaerobic

Justification- The amount of energy is high and consistent in aerobic and low in anaerobic.

(option b)

Aerobic Respiration

• Respiration which occurs in the presence of oxygen is called aerobic respiration.
• Organisms that only respire aerobically are called obligate aerobes. Example: plants, mammals.
• Aerobic respiration follows a series of steps in which a substrate (such as glucose) is broken down to release maximum energy.
• The energy currency of a cell is ATP. In aerobic respiration, the end product is 38 ATP.
• The process is more efficient and consistent than anaerobic respiration.

Anaerobic Respiration

• Respiration that occurs in the absence of oxygen is called anaerobic respiration.
• Organisms that only respire in an anaerobic environment are called obligate anaerobes. Examples: yeast, Clostridium, muscle tissues during vigorous exercise, etc.
• Anaerobic respiration can either be alcoholic fermentation or lactic acid fermentation.
• In both types, the yield of ATP is much less than that in aerobic respiration.

Therefore, the correct option is (b).
