The breakdown of pyruvate to give carbon dioxide water and energy takes place in

• Cytoplasm

• Mitochondria

• chloroplast

• Nucleus

Why do the walls of trachea not collapse when there is less air in it?

• Supported by rings of cartilage

• Supported by Rib cage

• No air is left the question is wrong

• Because of strong muscles

Why does lack of oxygen in muscles often lead to cramps among cricketers?

• Formation of lactic acid during lack of oxygen

• Conversion of pyruvate to ethanol and CO2 in absence of oxygen

• Due to formation of CO2 and H2O in mitochondria

• None of the above

The trachea divides into two smaller tubes called ______.

• Trachea
• Bronchi
• Alveoli
• Bronchioles

Which of the following processes transport oxygen from the alveoli into the capillaries?

• Respiration

• Inhalation

• Exhalation

• Diffusion

When inhalation

• Thoracic cavity become smaller

• The air pressure in the thoracic cavity increases

• The air pressure n the thoracic cavity decreases

• Air is pushed out
