Aerobic & Anaerobic Respiration

Aerobic vs Anaerobic Respiration

Aerobic respiration is respiration in the presence of oxygen. Anaerobic respiration is respiration in the absence of oxygen.

Aerobic respiration

In aerobic respiration, oxygen combines with glucose to produce energy in the mitochondria of the cells. The word equation for this process is:
- Glucose + oxygen → carbon dioxide + water (+ energy)
Aerobic respiration is ideal for endurance events because it has a moderate intensity that can be sustained over a period of time.

Anaerobic respiration

In anaerobic respiration, glucose is converted directly into energy. The word equation for this process is:
- Glucose → lactic acid (+ energy).
However, this can only be sustained for a short period of time because of the build-up of toxic lactic acid and a limited supply of glucose.

Differences

The main difference between aerobic and anaerobic respiration is how intense they are.

Aerobic

We need to inhale oxygen during aerobic respiration. This makes the respiration process longer and easier to keep up (moderate intensity).

Anaerobic

Anaerobic respiration is always accessible for converting glucose directly to energy. This makes it explosive (high intensity). However, this is not sustainable (easy to keep up).
