Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In cellular respiration, approximately 38% of the energy contained in glucose is released for an organism to use carrying out life processes. Which best explains what happens to the remaining 62% of the energy contained in glucose?
A
The energy is used to start the process of cellular respiration when more glucose is consumed by the organism.
B
The energy is used to convert leftover glucose into protein to be stored by the cells of the organism.
C
The energy is stored by the cells and released later when needed by the organim.
D
The energy is converted to thermal energy, which provides heat to the organism.
Explanation: 

Detailed explanation-1: -Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP (Figure below). ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street.

Detailed explanation-2: -So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria. Electron transfer from glycolysis’ NADH and FADH2 molecules, pyruvate transformation, and the Krebs cycle generates up to 32 additional ATP molecules.

Detailed explanation-3: -Electron Transport System generates 32 or 34 ATP molecules and is the cell’s main source of energy. Thus, the electron transport system produces the most ATP in cellular respiration.
