H gher and presumably toxic concentrations of quinidine sharply inhibited the oxidation of glucose and free fatty acids and accelerated the breakdown of glycogen. This profound effect of quinidine on oxidative myocardial metabolism may be an important factor in depressing myocardial excitability and ...
Insulin inhibits the breakdown of ... into glucose. 01:51 Name the hypercalcemic hormone 02:12 ... promotes the breakdown of glycogen into glucose. 02:23 The breakdown of glucose is called... 02:08 The synthesis of glucose from non-carbohydrate molecules is called 02:18 ... reduces ...
Pompe disease (OMIM 232300) is caused by mutations of the GAA gene and by deficiency of acid alpha-glucosidase (GAA, acid maltase), a lysosomal hydrolase involved in the breakdown of glycogen1. Lack of functional GAA results in the typical pathological hallmarks of the disease: i. extensive ...
Three intertwined sources drive lactate production in astrocytes: glycogen, glucose uptake through GLUT1 transporters, and glutamate uptake through EAATs. Glucose taken up from blood vessels, or derived from the breakdown of glycogen, is converted to pyruvate and subsequently lactate, which is ...
We demonstrate that c-di-GMP binding stimulates GlgX-mediated glycogen breakdown and describe crystal structures of S. venezuelae GlgX, which reveal the molecular mechanism by which c-di-GMP activates GlgX. Specifically, these structures show that c-di-GMP binding induces structural changes that ...
The hormone glucagons(胰高血糖素) stimulates the breakdown of stored glycogen in liver and muscle cells by the following enzymes. Which is the first enzyme that must be activated ( ) A.Protein kinase AB.Phosphorylase kinaseC.Glycogen phosphorylaseD.Protein phosphataseE. Protein phosphatase inhibitor...
[D]“是从中获得三磷酸腺苷的物质”是对文章第二段中“through the breakdown of muscle glycogen into lactic acid and adenosine triphosphate(ATP)”这句话的改写,为正确答案。文中没有提到加大三磷酸腺苷的需求和降低其含量的问题,所以[A]“加大了生物体对三磷酸腺苷的需求”和 [B]“降低了组织中三磷酸腺苷...
The breakdown of glucose provides energy and carbon materials in cells throughout all domains of life, powering the cellular machinery by diverse glycolytic pathways, including the Embden–Meyerhof–Parnas (EMP) pathway, the oxidative pentose phosphate (OPP) pathway, and the Entner–Doudoroff (ED) ...
carbohydrate, protein or fat metabolism. Glucose can be used to synthesize glycogen and other storage fuels or broken down further to provide energy for metabolic processes, a series of reactions collectively termed cellular respiration. The stages of glucose breakdown can be divided into four ...
The breakdown of glycans by bifidobacteria depends on a significant number of GHs located extracellularly or within the cell wall. Bifidobacteria have evolved several homologous enzymes with overlapping, yet different, substrate specificities. Different species have different intestinal adaptations to cope ...
