To understand what happens to the energy in the bonds of glucose during cellular respiration, let’s examine the overall process. The equation given represents the chemical reaction of cellular respiration:
[tex]\[ C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + \text{ATP} \][/tex]
Here is a detailed step-by-step solution to what happens during the reaction:
1. Glucose Breakdown: During cellular respiration, glucose ([tex]\( C_6H_{12}O_6 \)[/tex]) is oxidized.
2. Oxygen’s Role: Oxygen ([tex]\( O_2 \)[/tex]) is used as the electron acceptor in this reaction, and it combines with electrons and protons to form water ([tex]\( H_2O \)[/tex]).
3. Production of Carbon Dioxide and Water: The carbon atoms from glucose are released as carbon dioxide ([tex]\( CO_2 \)[/tex]), and the hydrogen atoms combine with oxygen to form water ([tex]\( H_2O \)[/tex]).
4. Energy Conversion: The energy stored in the bonds of glucose is released during these reactions.
5. Energy Transfer: The released energy is captured in the form of adenosine triphosphate (ATP), which cells use for various functions. Glucose’s energy is transferred into the high-energy phosphate bonds of ATP.
In summary, during cellular respiration, the original energy from the bonds in glucose is preserved and changed into a form the cell can use, i.e., ATP.
Thus, the correct answer to the question "What happens to the energy in the bonds in glucose?" is:
- The energy is transferred to ATP.
Therefore, the correct answer is option 4:
The energy is transferred to ATP.
