Che cos'è la respirazione cellulare?
Organisms harvest energy from food, but this energy cannot be directly used by cells. Cells convert the energy stored in nutrients into a more usable…
Che cos'è la glicolisi?
Cells make energy by breaking down macromolecules. Cellular respiration is the biochemical process that converts “food energy” (from…
Fasi della glicolisi che richiedono energia
Glucose is the source of nearly all energy used by organisms. The first step of converting glucose into usable energy is called glycolysis.…
Fasi della glicolisi che rilasciano energia
While the first phase of glycolysis consumes energy to convert glucose to glyceraldehyde 3-phosphate (G3P), the second phase produces energy. The…
Risultati della glicolisi
Nearly all the energy used by cells comes from the bonds that make up complex, organic compounds. These organic compounds are broken down into…
Ossidazione del piruvato
After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions…
Il ciclo dell'acido citrico
The citric acid cycle, also known as the Krebs cycle or TCA cycle, consists of several energy-generating reactions that yield one ATP molecule, three…
Prodotti del ciclo dell'acido citrico
The cells of most organisms—including plants and animals—obtain usable energy through aerobic respiration, the oxygen-requiring version…
Catene di trasporto degli elettroni
The final stage of cellular respiration is oxidative phosphorylation, which consists of (1) an electron transport chain and (2) chemiosmosis. The…
Chemiosmosi
Oxidative phosphorylation is a highly efficient process that generates large amounts of adenosine triphosphate (ATP), the basic unit of energy that…
Trasportatori di elettroni
Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be…
Rendimento di ATP
Cellular respiration produces 30-32 ATP molecules per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the…
Fermentazione
Most eukaryotic organisms require oxygen to survive and function adequately. Such organisms produce large amounts of energy during aerobic…
Interazioni metaboliche
Metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and…
Ad alta risoluzione respirometria mitocondriale per valutare la funzione in permeabilizzate e cellule intatte
A high-resolution oxygraph is a device for measuring cellular oxygen consumption in a closed-chamber system with very high resolution and sensitivity…
Un protocollo ottimizzato per analizzare glicolisi e mitocondriale respirazione nei linfociti
Lymphocytes respond to a variety of stimuli by activating intracellular signaling pathways, which in turn leads to rapid cellular proliferation,…
Trattare Topi SCA1 con solubile in acqua composti non-specifico Boost mitocondriale Funzione
Mitochondrial dysfunction plays a significant role in the aging process and in neurodegenerative diseases including several hereditary…
