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
