Anaerobic Respiration: Energy Production Without Oxygen

Anaerobic respiration, like aerobic respiration, converts glucose into ATP, providing energy when oxygen is scarce. In humans, it occurs in muscle cells during exercise, producing lactic acid as a byproduct. Bacteria also utilize anaerobic respiration in environments without oxygen.

What byproduct is produced during anaerobic respiration in muscle cells?

• Carbon dioxide

• Ethanol

• Lactic acid

• Glucose

Which organisms utilize anaerobic respiration in environments lacking oxygen?

• Humans

• Plants

• Bacteria

• All of the above
