Question

Explain the relationship between the biological processes of aerobic respiration and photosynthesis. How are the products and reactants similar and different? You may post a diagram to support your answer, but a full explanation is needed.

Answer 1

Photosynthesis and cellular respiration are linked processes: the products of one process are the reactants of the other. During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. During aerobic respiration, organisms use oxygen and glucose to produce carbon dioxide, water, and energy.

Step-by-step explanation:

Photosynthesis and cellular respiration are two biological processes that are closely linked and essential for life on Earth. During photosynthesis, plants use carbon dioxide and water to produce glucose (a sugar) and release oxygen. Meanwhile, during aerobic respiration, organisms use oxygen and glucose to produce carbon dioxide, water, and energy.

The overall chemical equation for photosynthesis is:

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

The overall chemical equation for aerobic respiration is:

C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy (ATP)

As you can see, the products of photosynthesis (glucose and oxygen) are the reactants of aerobic respiration, and vice versa.
