Question

Products of anaerobic respiration in muscles are (a) Lactic acid and energy (b) Lactic acid, carbon dioxide and energy (c) Lactic acid, water, carbon dioxide and energy (d) Lactic acid, water and energy

Answer 1

Products of anaerobic respiration in muscles are (a) Lactic acid and energy.

Anaerobic respiration:

• In anaerobic respiration, glucose is broken down to obtain energy in the absence of oxygen.
• Much less energy is obtained during anaerobic respiration.

Anaerobic respiration in muscle cells:

• Muscle cells respire aerobically normally, and at this time complete oxidation of glucose takes place producing carbon dioxide and water as end products along with the release of energy.
• However, during heavy exercise, a temporary deficiency of oxygen is experienced by the muscle cells. At this time, they respire anaerobically.
• The products of anaerobic respiration in muscle cells are lactic acid as well as energy.

$Glucose(muscle\:cells) \rightarrow Lactic\:acid+Energy \:(absence\:of\:oxygen)$

Answer 2

Answer:

(a) lactic acid and energy
