Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which way are photosynthesis and cellular respiration different?
A
Cellular respiration stores ATP, while photosynthesis releases ATP.
B
Cellular respiration produces oxygen, while photosynthesis uses oxygen.
C
Photosynthesis releases energy, while cellular respiration stores energy.
D
Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.
Explanation: 

Detailed explanation-1: -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-2: -Photosynthesis releases energy, while cellular respiration stores energy.

Detailed explanation-3: -Photosynthesis and cellular respiration are two biochemical processes that are essential to most life on Earth. Both of these processes involve multiple complex steps and many of the same molecules-oxygen (O2), carbon dioxide (CO2), water (H2O), glucose (C6H12O6), and adenosine triphosphate (ATP).

Detailed explanation-4: -While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis (Figure below) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.

Detailed explanation-5: -Photosynthesis is how plants combine light, water, and carbon dioxide to produce energy (glucose) and oxygen. The glucose powers the plants functions, and the oxygen is released back into the atmosphere. Cellular respiration is how animals combine glucose and oxygen to produce carbon dioxide and water.
