What is the function of the Bronchioles?
It enables gas exchange into the blood stream and oxygenates the blood.
What is the main component of Anaerobic respiration?
Glucose
What is the main product of Aerobic respiration in muscles?
CO2 and Water.
Why is smoking bad for your lungs?
It releases tar and arsenic which destroys the mucus producing cells that disables the process by which the cells stop pathogens, dust and germs.
Name the word equation for respiration in muscles after vigorous exercise
Define Anaerobic respiration
It is a type of internal respiration which does not use free oxygen.
Name the gases as well as their percentages that are inhaled from the air.
Oxygen-21%
Nitrogen-78%
Other gasses- 1%
Name the disadvantages of Anaerobic respiration
Less energy is released per glucose molecule than aerobic respiration.
They can only respire for a short period of time.
State the balanced equation for aerobic respiration
C6H12O6---> 6CO2 + 6H2O
Describe why and what the body requires energy for.
It needs energy for respiration, grown and repair.
Can cells permanently anaerobic respire?
No
Explain the effect of physical activity on your body.
During physical activity, sometimes anaerobic respiration is used because of the lack of oxygen entering the lungs to support the muslces.
State the path oxygen takes to be diffused into the bloodstream.
Nose->Larynx->Trachea->Bronchi->Bronchioles-> Alveoli->Capillaries.
Explain the process of bread making.
When used in bread making, the yeast begins by respiring aerobically, the carbon dioxide from which makes the bread rise. Eventually the available oxygen is used up, and the yeast switches to anaerobic respiration producing alcohol and carbon dioxide instead.
During intense exercise, muscle cells switch to anaerobic respiration. Explain why this shift occurs in anaerobic respiration in muscle cells.
During intense exercise, muscle cells experience an increased demand for energy due to rapid contraction. As oxygen supply becomes limited, aerobic respiration (which requires oxygen) cannot keep up with the energy demand. Consequently, muscle cells switch to anaerobic respiration.
