Question

cellular respiration occurs in the cells of all living organisms. what is the purpose of cellular respiration?

○ to make proteins

○ to make atp

○ to make oxygen

○ to make sugar

Explanation:

To determine the purpose of cellular respiration, we analyze each option:

• "To make proteins" is incorrect as protein synthesis is a different process (e.g., translation).
• "To make ATP" is correct. Cellular respiration breaks down glucose (or other substrates) to produce ATP, which is the energy currency of the cell.
• "To make oxygen" is incorrect; cellular respiration consumes oxygen (in aerobic respiration) or occurs without it (anaerobic), and oxygen production is from photosynthesis.
• "To make sugar" is incorrect; sugar (glucose) is made in photosynthesis, while cellular respiration breaks down sugar.

Answer:

B. to make ATP (assuming the second option is labeled B; if the original options had labels like A, B, C, D, adjust the identifier. Here, the second option "to make ATP" is the correct choice.)
