During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
16 de abr. de 2024 · Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. It includes glycolysis, the TCA cycle, and oxidative phosphorylation.

Cellular respiration is the process by which individual cells break down food molecules, such as glucose and release energy. The process is similar to burning, although it doesn’t produce light or intense heat as a campfire does.
La respiración celular es el proceso de oxidar moléculas de alimentos, como la glucosa, a dióxido de carbono y agua. C6H12O6 + 6O2 + 6H2O → 12H2O + 6CO2 (4.5.1) (4.5.1) C 6 H 12 O 6 + 6 O 2 + 6 H 2 O → 12 H 2 O + 6 C O 2.
Luego, una serie de vías metabólicas, llamadas colectivamente respiración celular, extrae la energía de los enlaces en la glucosa y la convierte en una forma que todos los seres vivos pueden usar, tanto productores, como plantas, y consumidores, como los animales.

When organic fuels like glucose are broken down using an electron transport chain, the breakdown process is known as cellular respiration. Electron carriers, also called electron shuttles, are small organic molecules that play key roles in cellular respiration.
