During anaerobic respiration in humans, what is produced instead of carbon dioxide and water?
What is Lactic Acid
What is the term for the maximum amount of air you can exhale after a deep breath?
What is vital capacity
What is the role of stomata in plants during gas exchange?
What is Allow gases like oxygen and carbon dioxide to move in and out
How does carbon monoxide affect the oxygen-carrying capacity of blood?
What is It binds to red blood cells, reducing their ability to carry oxygen
What is the name for the buildup of lactic acid during strenuous exercise?
What is anaerobic respiration
Why does anaerobic respiration release less energy than aerobic respiration?
What is it doesn't fully break down Glucose
What happens to pressure in the lungs during inhalation compared to outside the body?
What is Pressure in the lungs decreases and is lower than outside
Why is gas exchange necessary for respiration?
What is To supply oxygen for aerobic respiration and remove carbon dioxide
What is emphysema, and how is it caused?
What is A condition where alveoli break apart, reducing the surface area for gas exchange; caused by smoking
How does the body repay oxygen debt after exercise?
What is By increasing breathing rate to restore oxygen levels and remove lactic acid
What is "oxygen debt," and why does it occur?
What is the extra oxygen needed after exercise to replenish oxygen stores and remove lactic acid
What is the name for the volume of air taken in with each breath?
What is tidal volume
What happens to carbon dioxide when it is present in limewater?
What is it turns milky white
How does smoking affect the cilia in the lungs?
What is High temperatures stop them working, allowing mucus and dirt to collect
Why do muscles tire quickly during anaerobic respiration?
What is Less energy is released, and lactic acid buildup causes fatigue
