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 is the main purpose of converting glucose in the body?

• To generate ATP

• To produce lactic acid

• To form carbon dioxide

• To create oxygen

When does the human body primarily use anaerobic respiration?

• During intense exercise

• While eating

• During sleep

• When resting

What is a byproduct of anaerobic respiration in muscle cells?

• Glucose

• Lactic acid

• Water

• Carbon dioxide

Which organisms use anaerobic respiration in environments without oxygen?

• Plants

• Bacteria

• Animals

• Fungi

In what kind of environment do bacteria use anaerobic respiration?

• Oxygen-rich

• Oxygen-lacking

• High-pressure

• High-temperature
