Respiration in Organisms Quiz
Preview:
What is anaerobic respiration and give an example of it.
A. Anaerobic respiration is the process of producing energy using only oxygen. An example is the production of ATP in the mitochondria.
B. Anaerobic respiration is the process of producing energy without the use of oxygen. An example of anaerobic respiration is the fermentation of glucose by yeast to produce ethanol and carbon dioxide.
C. Anaerobic respiration is the process of producing energy using sunlight. An example is photosynthesis in plants.
D. Anaerobic respiration is the process of producing energy by breaking down food in the presence of oxygen. An example is cellular respiration in animals.
Describe the process of inhalation and exhalation in humans.
A. During inhalation, the chest cavity decreases in volume, while it increases in volume during exhalation.
B. Inhalation involves the movement of the ribs upward and outward, while exhalation involves the movement of the ribs downward and inward.
C. The diaphragm relaxes and moves downward during inhalation, while it contracts and moves upward during exhalation.
D. The diaphragm contracts and moves downward during inhalation, while it relaxes and moves upward during exhalation.
What happens to the carbon dioxide produced during respiration in organisms?
A. It is excreted through the skin
B. It is stored in the body
C. It is released as a waste product.
D. It is converted into oxygen
Differentiate between aerobic and anaerobic respiration.
A. Aerobic respiration produces more energy than anaerobic respiration.
B. Aerobic respiration requires oxygen, while anaerobic respiration does not require oxygen.
C. Aerobic respiration occurs in the absence of glucose, while anaerobic respiration occurs in the presence of glucose.
D. Aerobic respiration requires carbon dioxide, while anaerobic respiration requires oxygen.
Explain the process of glycolysis in cellular respiration.
A. Glycolysis is the process of breaking down pyruvate into glucose, producing ATP and NADH in the nucleus of the cell.
B. Glycolysis is the process of breaking down ATP into glucose, producing pyruvate and NADH in the cytoplasm of the cell.
C. Glycolysis is the process of breaking down water into glucose, producing oxygen and carbon dioxide in the mitochondria of the cell.
D. Glycolysis is the process of breaking down glucose into pyruvate, producing ATP and NADH in the cytoplasm of the cell.
What are the effects of lack of oxygen on the human body?
A. Increased energy and alertness
B. Improved lung function and capacity
C. Enhanced immune system response
D. Loss of consciousness and organ damage
What is the energy currency of the cell produced during aerobic respiration?
A. Glucose
B. Water
C. ATP
D. Carbon dioxide
What is the main site of gaseous exchange in humans?
A. Lungs
B. Stomach
C. Kidneys
D. Liver
How does the respiratory system in humans maintain the balance of oxygen and carbon dioxide in the body?
A. Through the process of gas exchange in the lungs
B. By filtering the air through the kidneys
C. By absorbing oxygen through the skin
D. By converting carbon dioxide into oxygen
How does the structure of the leaf in plants facilitate gaseous exchange?
A. Through small openings called stomata
B. By releasing oxygen into the air
C. Through the roots
D. By absorbing sunlight
How do plants release oxygen during photosynthesis?
A. Through the process of combustion
B. Through the process of fermentation
C. Through the process of dehydration
D. Through the process of photolysis
Why is oxygen important in the process of respiration?
A. Oxygen is used to produce carbon dioxide during respiration
B. Oxygen is not important in the process of respiration
C. Oxygen is only important for plants, not for animals
D. Oxygen is needed for the final step of cellular respiration, where it acts as the final electron acceptor in the electron transport chain.
Why is it important for cells to undergo respiration?
A. To store genetic information
B. To produce energy in the form of ATP for cellular activities
C. To regulate the cell’s temperature
D. To provide structural support for the cell
What are the similarities and differences between respiration in plants and animals?
A. Both use oxygen and produce carbon dioxide, but plants also undergo photosynthesis to produce their own food.
B. Plants and animals both use nitrogen for respiration.
C. Plants and animals both use photosynthesis to produce their own food.
D. Plants use carbon dioxide and produce oxygen, while animals use oxygen and produce carbon dioxide.
How do plants obtain oxygen for respiration?
A. Through photosynthesis
B. By taking it in through their leaves
C. By absorbing it from the soil
D. By obtaining it from the air through their roots
Explain the role of mitochondria in cellular respiration.
A. Mitochondria release oxygen through the process of cellular respiration.
B. Mitochondria produce glucose through the process of cellular respiration.
C. Mitochondria produce ATP through the process of cellular respiration.
D. Mitochondria store water through the process of cellular respiration.
What is the chemical equation for cellular respiration?

What are the end products of anaerobic respiration in animals?
A. proteins and fats
B. lactic acid or ethanol and carbon dioxide
C. water and carbon dioxide
D. glucose and oxygen
What is the process by which oxygen is taken in and carbon dioxide is given out by the human body?
A. Digestion
B. Photosynthesis
C. Excretion
D. Respiration
Explain the role of diaphragm in the mechanism of breathing.
A. The diaphragm helps in digestion by secreting digestive enzymes
B. The diaphragm has no role in the mechanism of breathing
C. The diaphragm helps in the process of inhalation and exhalation by changing the volume of the chest cavity.
D. The diaphragm only helps in exhalation and not in inhalation
