Question

practice it!
carefully read each statement, then select the statement(s) that are true about cellular respiration.
cellular respiration takes place in the mitochondria.
cellular respiration happens in the chloroplast.
cellular respiration only occurs in heterotrophs.
cellular respiration turns food into usable energy for cells.
cellular respiration occurs in both heterotrophs and autotrophs.

Explanation:

• Mitochondria are the primary site of cellular respiration (aerobic).
• Chloroplasts are for photosynthesis, not respiration.
• Autotrophs (e.g., plants) also perform cellular respiration to use the glucose they make, so it is not limited to heterotrophs.
• The core function of cellular respiration is breaking down food (glucose) to produce ATP, usable cellular energy.
• Both heterotrophs (consumers) and autotrophs (producers) carry out cellular respiration to generate energy for cell processes.

Answer:

• Cellular respiration takes place in the mitochondria.
• Cellular respiration turns food into usable energy for cells.
• Cellular respiration occurs in both heterotrophs and autotrophs.
