Question

Which statement is wrong for anaerobic respiration.

• A. $O_2$ is given out
• B. $C{O}_2$is given out
• C. $C{O}_2$is taken in
• D. $O_2$is taken in

Answer 1

The correct option is B $C{O}_2$is given out

• Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration.
• There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.
• Alcoholic fermentation is the process of converting glucose into the molecule ethanol.
• Lactic acid fermentation occurs in animals after glycolysis if there is not enough oxygen to perform aerobic respiration. One three-carbon molecule (pyruvic acid) is changed into another three-carbon molecule (lactic acid) and no carbon dioxide is produced like during other forms of respiration. Hence, CO2 is given out is wrong for anaerobic respiration.

So, the correct answer is 'CO2 is given out'.
