What is the importance of respiration?
A.) it breaks down food that is ingested to its building blocks
B.) it builds glucose molecules that are needed for producing energy in cells
C.) it produces energy that is needed for normal functioning of the cells
D.) it transports oxygen from the air to the cells.
A or C? I can’t choose
I do not think it is either A or C.
Think how do your lungs use O2 from the air ?
By the way plants use CO2 (perhaps exhaled from your lungs if not from your car exhaust) to make glucose and release O2 back to the air
The correct answer is C.) it produces energy that is needed for normal functioning of the cells.
Respiration is the process by which cells convert glucose and oxygen into energy, water, and carbon dioxide. This energy is in the form of adenosine triphosphate (ATP), which is the primary energy currency of cells. Therefore, respiration is vital for the normal functioning of cells and is essential for processes such as growth, maintenance, repair, and reproduction.
To arrive at this answer, you can break down the options:
A.) it breaks down food that is ingested to its building blocks - This describes the process of digestion, not respiration.
B.) it builds glucose molecules that are needed for producing energy in cells - This is incorrect. Glucose molecules are produced through the process of photosynthesis in plants, not respiration.
C.) it produces energy that is needed for normal functioning of the cells - This is the correct answer, as explained above.
D.) it transports oxygen from the air to the cells - This describes the process of respiration but only refers to one aspect of it. Respiration involves the exchange of gases, including the uptake of oxygen and the release of carbon dioxide, but its primary function is to produce energy.
