Cellular respiration and photosynthesis are functionally interrelated. These metabolic pathways exhibit interchangeable reactants and products.
<h3>Cellular respiration and photosynthesis</h3>
Cellular respiration refers to the metabolic reactions by which aerobic cells produce energy in the form of ATP and carbon dioxide by using the energy of chemical bonds of foods (eg., glucose) and oxygen.
Photosynthesis refers to the metabolic reactions by which plant cells produce simple carbohydrates (glucose), water and oxygen by using carbon dioxide and energy from the sun.
In consequence, oxygen and carbohydrates are the products of photosynthesis, whereas these materials are the reactants of cellular respiration (thereby both pathways are interrelated).
