RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What relationship do you notice about cellular respiration and photosynthesis?
A
They are the same processes.
B
The products of one process are the reactants of the other process.
C
They are unrelated because they involve completely different molecules.
D
They only occur in certain types of plants.
Explanation: 

Detailed explanation-1: -In the process of respiration, oxygen and glucose yield water and carbon dioxide, while carbon dioxide and water yield glucose and oxygen during the process of photosynthesis. Both cellular respiration and photosynthesis are parts of a mutually beneficial relationship.

Detailed explanation-2: -The products and reactants for photosynthesis are reversed in cellular respiration: The reactants of photosynthesis are carbon dioxide and water, which are the products of cellular respiration. The reactants of cellular respiration are oxygen and sugar, which are the products of photosynthesis.

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: -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-5: -Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it’s waste product of carbon dioxide (CO2).
