Question

Examine the model for two cellular organelles found in many eukaryotic cells. Which molecule(s) could be represented by the circle labeled Z that is produced as an output of the mitochondria and required by the chloroplast? Select ALL that apply. Responses Letter Z could be carbon dioxide because it is produced in cellular respiration and is a reactant of photosynthesis. Letter Z could be carbon dioxide because it is produced in cellular respiration and is a reactant of photosynthesis. Letter Z could be a water molecule because it is produced in cellular respiration and is a reactant of photosynthesis. Letter Z could be a water molecule because it is produced in cellular respiration and is a reactant of photosynthesis. Letter Z could be a water molecule because it is produced in photosynthesis and is a reactant of cellular respiration. Letter Z could be a water molecule because it is produced in photosynthesis and is a reactant of cellular respiration. Letter Z could be a glucose molecule because it is produced in photosynthesis and is a reactant of cellular respiration. Letter Z could be a glucose molecule because it is produced in photosynthesis and is a reactant of cellular respiration. Letter Z could be an oxygen molecule because it is produced in cellular respiration and is a reactant of photosynthesis. Letter Z could be an oxygen molecule because it is produced in cellular respiration and is a reactant of photosynthesis.

Answer 1

To analyze the outputs of mitochondria and the inputs required by chloroplasts, let’s consider the metabolic processes involved.

1. Mitochondria are responsible for cellular respiration. During this process, glucose and oxygen are consumed to produce carbon dioxide, water, and ATP (the energy currency of the cell).

2. Chloroplasts are involved in photosynthesis, where carbon dioxide and water are used in the presence of light to produce glucose and oxygen.

Now, let’s evaluate the different options for molecule Z:

• Carbon Dioxide:

  • It is produced in cellular respiration (by mitochondria).
  • It is a reactant in photosynthesis (by chloroplasts).
  • This could be represented by Z.

• Water:

  • Water is produced during cellular respiration when glucose is metabolized.
  • Water is a reactant in photosynthesis.
  • This could also be represented by Z.

• Glucose:

  • Glucose is produced during photosynthesis.
  • It is a reactant in cellular respiration.
  • This could be represented by Z.

• Oxygen:

  • Oxygen is produced during cellular respiration (as a byproduct).
  • It is a reactant in photosynthesis.
  • This could not be represented by Z, as oxygen is not an output of mitochondria but rather a byproduct.

Thus, the molecules that could be represented by the circle labeled Z are:

• Carbon Dioxide
• Water
• Glucose

Oxygen does not qualify as it is not produced in the same manner as the others in mitochondrial processes.
