What do muscles need more of during exercise?
Oxygen
Energy (Glucose)
Carbon Dioxide
Water
What is the correct equation for aerobic respiration?
C6H1402 + 6O2 → 6CO2 + 6H20
C6H12O6 + 6O2 → 6CO2 + 6H2O
C6H12O2 + 6O2 → 6CO2 + 6H2O
What are the two waste products of aerobic respiration?
Energy & Oxygen
Hydrogen & Water
Carbon Dioxide & Water
Carbon Dioxide & Glucose
Which substance is stored in the muscles and can be converted into glucose?
Potassium
Red Blood Cells
Lactic Acid
Glycogen
What is the word equation for aerobic respiration?
glycogen + water → carbon dioxide + glucose (+energy)
glucose + oxygen → carbon dioxide + water (+ energy)
energy + water → water + carbon dioxide
Why do muscles become fatigue during a prolonged physical activity?
The lungs have not taken in enough carbon dioxide.
The body is always dehydrated.
Lactic acid builds up in the muscles, making them hurt.
During exercise, breathing rate decreases.
During exercise heart rate increases.
Why do blood vessels dilate during exercise?
To allow an increase in blood supply to the muscle cells to provide them with oxygen and glucose quickly and to remove carbon dioxide quickly.
So that the lactic acid can pass out easier through the walls of the veins.
