  2. Biological functions of nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Biological_functions_of...

    When inhaled, nitric oxide dilates the pulmonary vasculature and, because of efficient scavenging by hemoglobin, has minimal effect on the vasculature of the entire body. [84] Inhaled nitric oxide appears to increase the partial pressure of arterial oxygen (P a O 2) by dilating pulmonary vessels in better-ventilated areas of the lung, moving ...

  3. Evolution of metal ions in biological systems - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_Metal_Ions_in...

    ATP, the main source of energy in almost all living organisms, must bind with metal ions such as Mg 2+ or Ca 2+ to function. Examination of cells with limited magnesium supply has shown that a lack of magnesium can cause a decrease in ATP. [9] Magnesium in ATP hydrolysis acts as a co-factor to stabilize the high negative charge transition state ...

  4. Magnesium in biology - Wikipedia

    en.wikipedia.org/wiki/Magnesium_in_biology

    Mg 2+ may be taken up into cells immediately (symplastic pathway) or may travel as far as the Casparian band (4) before being absorbed into cells (apoplastic pathway; 2). The concentration of Mg 2+ in the root cells is probably buffered by storage in root cell vacuoles (3). Note that cells in the root tip do not contain vacuoles.

  5. Biometal (biology) - Wikipedia

    en.wikipedia.org/wiki/Biometal_(biology)

    Sodium is a metal where humans have discovered a great deal of its total roles in the body as well as being one of the only two alkali metals that play a major role in the bodily functions. It plays an important role in maintenance of the cell membrane potential and the electrochemical gradient in the body via the sodium-potassium pump and ...

    The result is an overall increase in endogenous ROS, which when above a cellular tolerability threshold, may induce cell death. [76] On the other hand, normal cells appear to have, under lower basal stress and reserve, a higher capacity to cope with additional ROS-generating insults than cancer cells do. [77]

    Nitric oxide is an important signaling molecule that your body uses for a wide variety of different functions, including supplying blood to your member when you’re aroused. It’s certainly an ...

  8. Nitric oxide synthase - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide_synthase

    Nitric oxide synthases (EC 1.14.13.39) (NOSs) are a family of enzymes catalyzing the production of nitric oxide (NO) from L-arginine. NO is an important cellular signaling molecule. It helps modulate vascular tone , insulin secretion, airway tone, and peristalsis , and is involved in angiogenesis and neural development.

    According to Kukushkin, the memories stored in non-brain cells in other parts of the body are memories strictly related to the roles that those specific cells play in human health. Thus, he detailed:
