State two differences between aerobic and anaerobic respiration.

Two key differences between aerobic and anaerobic respiration are:
1. Oxygen requirement: Aerobic requires oxygen, anaerobic occurs without oxygen
2. Energy yield: Aerobic produces more ATP (38 molecules) than anaerobic (2 ATP molecules)

Step-by-Step Solution:
Aerobic equation: Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP)
Anaerobic equation: Glucose → Lactic acid + Energy (ATP)
Compare products: Aerobic produces CO2 + H2O vs Anaerobic produces lactic acid
Energy check: Aerobic is more efficient (38 ATP vs 2 ATP)

Key Mistake to Avoid:
Don't confuse the products - lactic acid is ONLY produced in anaerobic respiration in animals, not in aerobic respiration.

Quick Tip:
Remember "A for Abundant" - Aerobic respiration produces Abundant ATP (38) compared to anaerobic (2).
