RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
After cellular respiration is complete, on 38% of the energy in glucose is used. What happens to the rest of the energy?
A
released as heat
B
stored for later use
C
eliminated by the digestive system
D
turned into protein
Explanation: 

Detailed explanation-1: -Energy contained in the bonds of glucose is released in small bursts, and some of it is captured in the form of adenosine triphosphate (ATP), a small molecule that powers reactions in the cell. Much of the energy from glucose is dissipated as heat, but enough is captured to keep the metabolism of the cell running.

Detailed explanation-2: -Through the production of ATP, the energy derived from the breakdown of sugars and fats is redistributed as packets of chemical energy in a form convenient for use elsewhere in the cell.

Detailed explanation-3: -During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).

Detailed explanation-4: -One ATP provides 7.3 kcal energy. Therefore, 38 ATP yields 227.4 Kcal energy.

Detailed explanation-5: -Some amount of energy released during respiration is lost in the form of heat while the rest is converted into ATPs and stored in the cells, which are later utilised to carry out all the life processes like photosynthesis, growth and reproduction, etc.
