New Section

In this section, we will explore the general aspects of cellular respiration and its two main types: anaerobic respiration and aerobic respiration.

General Aspects of Cellular Respiration

  • Cellular respiration is the process by which the body extracts energy from food, such as carbohydrates, lipids, and proteins.
  • The digestive system plays a crucial role in breaking down food into macromolecules.
  • Carbohydrates, particularly glucose, provide more energy for cellular respiration compared to proteins and lipids.
  • Enzymes within cells break the chemical bonds of glucose to release accumulated energy.
  • Cellular respiration involves more than just a gas exchange like breathing; it is a complex metabolic process.

Anaerobic Respiration

  • Anaerobic respiration is a process where glucose is oxidized for energy without the presence of oxygen.
  • This type of respiration is exclusive to certain prokaryotic organisms, such as bacteria.

Aerobic Respiration

  • Aerobic respiration is a set of reactions that occur with the presence of oxygen.
  • It involves the separation of pyruvic acid produced in glycolysis into carbon dioxide and water, producing large amounts of ATP (adenosine triphosphate).
  • Aerobic respiration takes place in two phases: glycolysis and the Krebs cycle (citric acid cycle) with electron transport.
  • Glycolysis occurs in the cytoplasm under anaerobic conditions and produces 2 pyruvates, 2 ATP, and 2 NADH.
  • The pyruvate molecules can undergo lactic fermentation or alcoholic fermentation when there is no oxygen present.
  • When oxygen is available, pyruvic acid travels to the mitochondria to initiate the Krebs cycle. This cycle involves a series of chemical reactions that release stored energy through the oxidation of acetyl coenzyme derived from carbohydrates, lipids, and proteins.
  • The Krebs cycle produces 36 ATP, 6 water molecules, and 6 carbon dioxide molecules.

#bioquímica#GLUCÓLISIS#ciclodekrebs La respiración celular es una de las vías más elegantes, majestuosas y fascinantes en la Tierra. También es una de las más complicadas. Cuando aprendí sobre ella por primera vez, ¡sentí que me había tropezado y caído en una lata de sopa de letras sabor química orgánica! Por suerte, la respiración celular no es tan intimidante una vez que te familiarizas con ella. Vamos a comenzar a ver la respiración celular desde un nivel alto, pasaremos por cada una de las cuatro principales etapas y señalaremos la manera en que se conectan entre sí.
