Matter constantly cycles through the earth's spheres using many different processes. Photosynthesis and cellular respiration are two important processes in this cycling of matter. The products of photosynthesis are reactants in cellular respiration. The products of cellular respiration are the reactants of photosynthesis. This model shows the cycling of matter through these cycles. The model is unlabeled. Correctly label the products and reactants of cellular respiration. Choose ALL three that apply. Responses A A = ATPA = ATP B B = CO2 + H2OB = CO 2 + H 2 O C A = C6H12O6A = C 6 H 12 O 6 D D = O2 + C6H12O6D = O 2 + C 6 H 12 O 6 E B = O2 + C6H12O6

To correctly label the products and reactants of cellular respiration, let's first outline the general equation for cellular respiration:

\[ \text{C}6\text{H}{12}\text{O}_6 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} + \text{ATP} \]

From this equation, we can identify the following:

Reactants:

  • Glucose (\(C_6H_{12}O_6\))
  • Oxygen (\(O_2\))

Products:

  • Carbon dioxide (\(CO_2\))
  • Water (\(H_2O\))
  • ATP (energy)

Now, we can label the responses based on the role they play in cellular respiration:

  • A = ATP : This represents a product of cellular respiration.
  • B = CO2 + H2O: This represents the products of cellular respiration.
  • C = C6H12O6: This represents a reactant of cellular respiration.
  • D = O2 + C6H12O6: This includes one reactant (O2) and one reactant (C6H12O6).
  • E = O2 + C6H12O6: Similar to D, it includes one reactant (O2) and one reactant (C6H12O6).

For labeling the products and reactants of cellular respiration, you select:

  • A = ATP (product)
  • B = CO2 + H2O (products)
  • C = C6H12O6 (reactant)

Therefore, the correct responses to label the products and reactants of cellular respiration are:

  • A (ATP)
  • B (CO2 + H2O)
  • C (C6H12O6)
