Question

question 1 - 6
how are the processes of photosynthesis and cellular respiration interrelated?
photosynthesis releases energy and cellular respiration stores energy.
photosynthesis is unique to plants and cellular respiration is unique to animals.
the products of photosynthesis are carbon dioxide and water; cellular respiration produces oxygen and sugars.
photosynthesis removes carbon dioxide from the atmosphere and cellular respiration releases carbon dioxide into the atmosphere.

Explanation:

• Photosynthesis uses carbon dioxide (\(CO_2\)) and water (\(H_2O\)) to produce glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)). The equation is \(6CO_2 + 6H_2O

ightarrow C_6H_{12}O_6+6O_2\).

• Cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and energy. The equation is \(C_6H_{12}O_6 + 6O_2

ightarrow6CO_2 + 6H_2O+energy\).

• Photosynthesis stores energy (in the form of chemical bonds in glucose) and cellular respiration releases energy (by breaking the chemical bonds in glucose). So the first option is wrong.
• Both plants and animals (and many other organisms) carry out cellular respiration. Plants carry out photosynthesis (some bacteria also photosynthesize). So the second option is wrong.
• As per the equations above, the products of photosynthesis are glucose and oxygen, and the products of cellular respiration are carbon dioxide and water. So the third option is wrong.
• Photosynthesis removes \(CO_2\) (uses it as a reactant) from the atmosphere and cellular respiration releases \(CO_2\) (as a product) into the atmosphere.

Answer:

Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration releases carbon dioxide into the atmosphere.
