The presence of large amounts of adenosine triphosphate in phenol extracts of chicken lenseslivestock, zoology, animal scienceRNA obtained from chicken lenses by phenol extraction and ethanol precipitation is contaminated with large amounts of a dialyzable, ultraviolet-absorbing material. Analysis of ...
4). Mitochondria, which are a very important and abundant organelle type in the cytoplasm, are involved in various processes, such as generating adenosine triphosphate (ATP), establishing developmental competence, maintaining calcium homeostasis, and regulating apoptosis59. It is well known that ...
Discrete events measure single quanta of adenosine 5'-triphosphate secreted from sympathetic nerves of guinea-pig and mouse vas deferens. Intracellularly recorded excitatory junction potentials in smooth muscle cells, and the first time differentials of their rising phases ("discrete events")... Stj?
The mechanism for this reaction is modeled as Hill kinetics with the Hill coefficient h = 4, where adenosine monophosphate (AMP), acting as an external activator, and adenosine triphosphate (ATP), acting as an inhibitor, bind to the same site. Detailed account about the used kinetic mechanisms...
The breakdown of adenosine triphosphate (ATP) into adenosine diphosphate (ADP) is: a. an exergonic and catabolic process. b. an exergonic and anabolic process. c. an endergonic and anabolic process. d. an endergonic and catabolic process. Which enzyme cat...
The extension product of villin was 105 bp, indicating that the transcriptional start site (an adenosine residue subsequently designed as nucleotide +1) was 57 nucleotides upstream of the translation initiation codon of the murine villin cDNA (Fig. 1 B). Comparison of the genomic sequence ...
All of these experimental methods need copious amounts of highly pure RNA to answer the different questions about RNA biology and structure. Unfortunately, working with RNA is hindered by one major hurdle, the ubiquitous presence of RNases, proteins that degrade RNA at a high rate. This require...

Adenosine triphosphate (ATP) is released from cholangiocytes into bile and is a potent secretogogue by increasing intracellular Ca2+ and stimulating fluid and electrolyte secretion via binding purinergic (P2) receptors on the apical membrane. Although morphological differences exist between small and ...
