Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are the reactions for photosynthesis and cellular respiration related?
A
The glucose and oxygen produced in photosynthesis are used as reactants in aerobic cellular respiration.
B
The glucose and oxygen produced in photosynthesis are used as reactants in anaerobic cellular respiration.
C
The carbon dioxide and water produced in photosynthesis are used as reactants in aerobic cellular respiration.
D
The carbon dioxide and water produced in photosynthesis are used as reactants in anaerobic cellular respiration.
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 makes glucose which is used in cellular respiration for making ATP. The glucose is then transformed back into carbon dioxide, which is used in photosynthesis. It helps cells to release and store energy. It maintains the atmospheric balance of carbon dioxide and oxygen.

Detailed explanation-3: -Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

Detailed explanation-4: -Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Detailed explanation-5: -In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
