Question

autotrophs and heterotrophs obtain energy from glucose (c₆h₁₂o₆) and other carbon - based molecules. their cells break down these energy - rich molecules during digestion and cellular respiration. through these processes, carbon - containing gases are released into the atmosphere.
the process of cellular respiration is represented by this chemical equation.
c₆h₁₂o₆ (aq)+6o₂ (g)→6co₂ (g)+6h₂o (l)+energy
glucose oxygen carbon dioxide water
select the true statements.
only heterotrophs perform cellular respiration.
cellular respiration produces water and carbon dioxide.
energy is released during cellular respiration.
cellular respiration moves carbon from the atmosphere to the biosphere.

Explanation:

1. Both autotrophs and heterotrophs perform cellular respiration to obtain energy, so the statement "Only heterotrophs perform cellular respiration" is false.
2. From the chemical - equation of cellular respiration $C_{6}H_{12}O_{6(aq)}+6O_{2(g)}

ightarrow6CO_{2(g)} + 6H_{2}O_{(l)}+energy$, it is clear that water and carbon dioxide are produced, so the statement "Cellular respiration produces water and carbon dioxide" is true.

1. The equation also shows that energy is released during cellular respiration, so the statement "Energy is released during cellular respiration" is true.
2. Cellular respiration releases carbon - containing gases (carbon dioxide) from organisms into the atmosphere, not moving carbon from the atmosphere to the biosphere. Photosynthesis moves carbon from the atmosphere to the biosphere. So the statement "Cellular respiration moves carbon from the atmosphere to the biosphere" is false.

Answer:

Cellular respiration produces water and carbon dioxide.
Energy is released during cellular respiration.
