RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are cellular respiration and photosynthesis related, in terms of energy?
A
The energy captured in photosynthesis is used to power cellular respiration.
B
The energy transformed in cellular respiration is used to power photosynthesis.
C
Photosynthesis and respiration perform the same task in terms of energy transformation.
D
Energy is not involved in either photosynthesis or cellular respiration.
Explanation: 

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

Detailed explanation-2: -The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

Detailed explanation-3: -Photosynthesis and cellular respiration are related in terms of energy because one harvests the energy from the Sun to produce food, while the other takes that food and makes energy for the organism. To start, photosynthesis is the process that takes sunlight, water, and carbon dioxide and produces glucose and oxygen.

Detailed explanation-4: -Photosynthesis uses the energy from the sun by converting carbon dioxide and water into glucose and oxygen. On the other hand, cellular respiration is the process in which glucose and oxygen are converted into energy. Therefore, these two processes are related to each other in terms of their reactants and products.

Detailed explanation-5: -Photosynthesis vs. cellular respiration 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.
