Soc 18- Aerobic, Anaerobic Exercise And Energy Sources Flashcards
Aerobic respiration word eqation
Glucose + oxygen -> Carbon dioxide + water + energy
Anaerobic respiration word equation
Glucose -> energy + lactic acid
Examples of Anaerobic sports
Sprinting, weight lifting
Effects of Lactic Acid (build up)
Cramp and the muscles stop working. You have to rest while the blood supplies oxygen to your muscles so that they recover
Glucose
A major source of energy for most cells in the body
Aerobic respiration
The process of releasing energy from glucose, using oxygen
Anaerobic respiration
The process of releasing energy from glucose, without oxygen.
Aerobic exercise
Working at a moderate intensity allowing the body time to utilise oxygen for energy production and to work for a continuous period .
Lactic acid
A colourless acid produced in muscle tissues during strenuous exercise when the body is exercising anaerobically at a high intensity.
Cramp
Painful, involuntary contraction of a muscle, ususally caused by fatigue
Two main sources of energy
Carbohydrates and fats
Energy source for high intensity exercise
Carbohydrates
Energy source for low intensity exercise for long periods
Fats
What happens when you eat fats?
It is broken down into fatty acids, which are abSorbed into your blood and delivered to your cells. If nott needed thay can be stored in fat cells
Foods containing fats
Butter, margarine, cooking oils and bacon, cheese, fish, nuts
