Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the relationship between cell respiration and photosynthesis?
A
Nothing
B
They are reverse reactions.
C
They are the same, but opposite.
D
They both use sunlight.
Explanation: 

Detailed explanation-1: -Respiration and Photosynthesis are almostopposite processes because photosynthesis removes carbon dioxide from the atmosphere while respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it’s waste product of carbon dioxide (CO2).

Detailed explanation-2: -Because respiration releases energy it is chemically the reverse of photosynthesis, which uses energy from the Sun to make organic molecules. Photosynthesis and respiration are also connected ecologically because the vast majority of organisms use the oxygen produced by photosynthesis for respiration.

Detailed explanation-3: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

Detailed explanation-4: -How are cellular respiration and photosynthesis almost opposite processes? Photosynthesis releases energy, and cellular respiration stores energy. Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.

Detailed explanation-5: -Cellular respiration and photosynthesis are almost opposite processes because in photosynthesis, the sugar glucose is formed and in cellular respiration, glucose is broken apart. The purpose of photosynthesis is to use the sun’s energy to convert carbon dioxide and water into glucose.
