CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which explains the connection between photosynthesis and cell respiration?
A
The input for both is sunlight
B
The inputs for both are carbon dioxide
C
The outputs are the same for both equations
D
The outputs of photosynthesis are the inputs of cell 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: -So, the output of photosynthesis (glucose and oxygen) is used as the input for cellular respiration, while the output of cellular respiration (carbon dioxide and water) is used as the input for photosynthesis. They are essentially reciprocal processes.

Detailed explanation-3: -Explanation: In photosynthesis, water, carbon dioxide, and energy in the form of sunlight are inputs, and the outputs are glucose and oxygen. A nonspontaneous reaction is one that will not proceed without the net input of energy (in this case, sunlight).

Detailed explanation-4: -Answer and Explanation: The main inputs of cellular respiration are glucose and oxygen. The main outputs of cellular respiration are carbon dioxide, water and energy in the form of ATP.

Detailed explanation-5: -Plants release oxygen which is a by-product of photosynthesis, and we breathe in oxygen so that our cells can carry out cellular respiration and generate ATP. Respiration and photosynthesis are biological reactions in the environment that complement each other.
