Question

Now that you have studied the process of cellular respiration, why do individuals who develop pneumonia (could be viral of bacterial) and are unable to get enough oxygen become so ill and could possibly die.

Answer 1

• Pneumonia is an infection of lungs caused by bacteria , virus , fungi.
• Due to infection , airway get swelled and air sac get filled with mucus and other fluids.
• Inorder to lung to perform best , airway need to be open inorder to breathe in and out .Swelling (inflammation) and mucus in the can make it harder to move air through the airways, making it harder to breathe.
• This leads to shortness of breath , difficulty breathing and feeling more tired than normal.
• Cell require oxygen for cellular respiration, due to shortness and difficulty breathing cells doesnot get enough oxygen .Which leads to decrease in energy production and leads to tiredness(ill) and ultimately it lead into death.
