Respiration in Organisms Quiz
Preview:
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
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.
What is the significance of carbon dioxide in respiration?
A. Carbon dioxide is a waste product that has no role in respiration.
B. Carbon dioxide is used to create energy in the form of ATP.
C. Carbon dioxide is only produced during exercise and not at rest.
D. Carbon dioxide is significant in respiration as it regulates breathing and maintains blood pH.
Define anaerobic respiration.
A. Anaerobic respiration occurs only in plants during photosynthesis.
B. Anaerobic respiration requires oxygen to produce energy.
C. Anaerobic respiration is the process of breathing without air.
D. Anaerobic respiration is the process of producing energy without oxygen.
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 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
What are the two main types of respiration?
A. Aerobic respiration and anaerobic respiration
B. Oxidative phosphorylation and glycolysis
C. Photosynthesis and fermentation
D. Cellular respiration and combustion
What is the energy currency of the cell produced during aerobic respiration?
A. Glucose
B. Water
C. ATP
D. Carbon dioxide
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 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.
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.
How do fish breathe underwater?
A. Fish breathe underwater using gills to extract oxygen from water.
B. Fish breathe through their skin to absorb oxygen.
C. Fish extract oxygen from the surface of the water.
D. Fish use lungs to breathe air like mammals.
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.
How does oxygen enter the bloodstream?
A. Oxygen enters the bloodstream via the stomach.
B. Oxygen enters the bloodstream through the alveoli in the lungs.
C. Oxygen is absorbed through the skin.
D. Oxygen is transported by red blood cells from the liver.
What is the function of alveoli in the lungs?
A. To produce mucus for lubrication in the lungs.
B. To filter out dust and particles from the air.
C. To store oxygen for later use.
D. The function of alveoli in the lungs is to enable gas exchange between the air and the bloodstream.
