Aerobic and anaerobic respiration

Define aerobic respiration.

Breakdown of glucose in the presence of oxygen.

How much energy does aerobic respiration release and what is the energy also released as.

Aerobic respiration releases a large amount of energy.

Energy is also released as heat,which is circulated around the body by blood to keep us warm.

chemical equation for aerobic respiration

C6H12O6 + 6O2 → 6CO2 + 6H2O + energy

Word equation for aerobic respiration

Glucose + oxygen → carbon dioxide + water + energy

What is Respiration

Glucose + oxygen → carbon dioxide + water + energy

define anaerobic respiration

Breakdown of glucose in the absence of oxygen.releases small amount of energy.

Word equation for anaerobic respiration

Glucose → lactic acid + energy

Why do people pant after exercise

To remove carbon dioxide and take in oxygen at a faster rate.

Why does the heart beat faster after exercise

So that glucose and oxygen can be transported to the muscles faster

Why do I need anaerobic respiration even if I pant and heart beat faster

There is a limit to the rate of breathing and heart beat.

If vigorous muscular contractions continue,extra energy needs to be released. Thus, muscle cells will respire anaerobically.

What happens when I accumulate lactic acid

Accumulation of lactic acid results in fatigue and muscular pains.
