# Qual è l'equazione chimica per la respirazione cellulare?

#### Risposta:

The overall (unbalanced) chemical equation for cellular respiration is:

"C"_6"H"_12"O"_6 + "O"_2 → "CO"_2 + "H"_2"O" + "energy"

#### Spiegazione:

The balanced equation is

"C"_6"H"_12"O"_6 + "6O"_2 → "6CO"_2 + "6H"_2"O" + "energy"

The equation expressed in words would be:

"glucose + oxygen → carbon dioxide + water + energy"

The equation is formulated by combining the three following processes into one equation:

1. La glicolisi — the breakdown of the form of a glucose molecule into two three-carbon molecules i.e. pyruvate (pyruvic acid).

2. The Tricarboxylic Acid Cycle or Krebs Cycle — the three-carbon pieces are pulled apart bit by bit to release the energy stored in those covalent bonds. This is where most of the "CO"_2 è formato.

3. The Electron Transport Chain e Oxidative Phosphorylation — this sequence requires the "O"_2 and produces most of the energy. This energy comes in the form of "ATP", or adenine triphosphate.
