Which is correct about CO2 released in cellular respiration?

Health
1 answer:
boyakko [2]3 years ago
6 0

Answer:

c. CO₂ is what is left from the carbon chain of glucose after removal of H (electrons and H+).

Explanation:

During aerobic respiration, a glucose molecule is completely broken down into CO₂ and water. The complete chemical reaction is:

C₆H₁₂O₆ + 6 O₂ -------> 6 CO₂ + 6 H₂O + energy

The glucose is oxidized (loses protons and electrons) to CO₂, and oxygen is reduced (accepts electrons) forming water.

Some intermediate reactions take place in the cytoplasm, while others occur in the mitochondria, where ATP (energy) is produced during the electron transport chain.
