Biology - Respiration in mammals

Anaerobic

Oxygen Debtt

Explains why we breath quickly after exercise

The Amount of oxygen needed to Oxidise lactic acid to carbon dioxide and water

Muscle Fatigue

Muscles become tired after exercise so they dont contract as efficiently

Lactic acid

Removed by blood flow through the muscles

Glucose -- Lactic acid + Energy

Waste Product is Lactic acid

Releases 5% of the energy released by Aerobic Respiration per molecule of glucose

Involves the incomplete breakdown of glucose

When insufficient amount of oxygen reaches the muscles

Aerobic

Muscles

Glycogen can be converted back to Glucose for use during exercise

Store Glucose as Glycogen

During Exercise the muscle cells respire more than they do at rest

Exercise

Increased rate of breathing increases rate of Gaseous Exchange in the lungs

The Increased Heart rate increases the rate of blood flow

Waste Carbon Dioxide must be removed more quickly

Oxygen and Glucose must be delivered more quickly

Energy released can be used to build larger molecules

Most Reactions happen inside the Mitochondria

Happens all the time in the cells

Glucose + Oxygen -- Carbon Dioxide + Water + Energy

Carbon Dioxide and Water are Waste products
