What is glucose
A major source of energy for most cells in the body
What is aerobic respiration
the process of releasing energy from glucose,
using oxygen.
What is anerobic respiration
the process of releasing energy from glucose, without oxygen.
What is Aerobic exercise:
working at a moderate intensity allowing the body time to utilise oxygen for energy production and to work for a continuous period, e.g. long~ distance events.
What is anerobic exercise
anaerobic activities are usually short but intense e.g. sprinting, lifting weights and jumping.
Working at high intensity with no oxygen
What is lactic acid?
a colourless acid produced in muscle tissues during strenuous exercise when the body is exercising anaerobically at high intensity.
What is a cramp?
painful, involuntary contraction of a muscle, usually caused by fatigue.
What is the word equation for aerobic respiration
Glucose + oxygen -> carbon dioxide + water + energy = aerobic respiration
What is the equation for aerobic respiration (letters and numbers)
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
How does glucose and oxygen get to the working msucles
Via the blood stream
What are the waste products
Carbon dioxide and water
What is the word equation for anerobic respiration
Glucose -> energy + lactic acid = anerobic respiration
What does lactic acid build up do to the muscles
Make them ache
