What is the true ATPase activity of contracting myofibrils?Tamura, YNishimoto, TMiyakami, SSako, HSaito, KMori, H
ATPase activity generally refers to the breakdown of ATP, releasing energy for cellular processes, whereas ATP Synthase activity is synonymous with energy storage, capturing energy in the form of ATP. The direction of the reaction—synthesis or hydrolysis—depends on the specific enzyme and the cellu...
However, in certain cases, the activity of these pathways can lead to aberrant DNA repair, genomic instability and tumorigenesis. One such case is DNA repair at the natural ends of linear chromosomes, known as telomeres, which can lead to chromosome-end fusions. Here, we review data obtained ...
What is the term for the myosin head flexing into a bend, and pulling the actin myofilament along with it? What skeletal muscle fiber type has slow myosin ATPase activity? ___ - bridges form when myosin head binds to active sites on G actin molecules. Fill...
When the F1 portion of the ATP synthase complex is removed from the mitochondrial membrane and studied in solution, it functions as an ATPase. Why does it not function as an ATP synthase? (a) Explain the processes of ATP hydrolysis. (b) Explain the processes of ADP phosphorylation. ...
Potassium-induced relaxation as an indicator of Na+-K+ ATPase activity in vascular smooth muscle. of the potassium-induced relaxation was employed as an index of the activity of the electrogenic sodium-potassium pump and hence of the Na+-K+ ATPase... R C,Webb,D F,... - 《Blood Vessels...
Why is smooth muscle slower than skeletal? The tension generated is relative to the amount of calcium concentration within the cell.ATPase activity is much lower in smooth muscle than itis in skeletal muscle. This factor leads to a much slower cycling speed of smooth muscle. ...
Phosphorylation of the plant immune regulator RPM1-INTERACTING PROTEIN4 enhances plant plasma membrane H(+)-ATPase activity and inhibits flagellin-triggered immune responses in Arabidopsis. Plant Cell 27, 2042–2056 (2015). CAS PubMed PubMed Central Google Scholar Zhou, Z. et al. An Arabidopsis...
actively involved in the catalysis of the ATP from adenosine diphosphate (ADP), and the inorganic phosphate molecules (Pi). The reaction is thermodynamically favored during cellular respiration in the presence of the electrochemical gradient of protons (H+) in add...
