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.
