cellular respiration

n.
The series of metabolic processes by which living cells produce energy through the oxidation of organic substances.

cel·lu·lar respiration

(sĕl′yə-lər)
The process of metabolism in which cells obtain energy in the form of ATP by causing glucose and other food molecules to react with oxygen.

According to the University of Iowa, vitamins such as the vitamin B complex is essential for cellular respiration. A scarce amount of these vitamins in the body can cause metabolic byproducts to accumulate and eventually damage nerve cells.
It also contains Vitamin B3, which aids the formation of co-enzymes involved in cellular respiration. It provides the energy that the body needs on daily basis.
Hydrogen cyanide, which results from the burning of plastics, interferes with cellular respiration, leading to loss of consciousness.
Antioxidants tend to neutralize the cancer-causing free radicals that develop as a by-product of cellular respiration resulting in a widespread adaptation of sarsaparilla for cancer-prevention in turn leading to growth in market demand.
Pyocyanin regulates the redox mechanism and initiate the production of reactive oxygen species which in turns inhibits cellular respiration, reduction in level of ATP and cAMP thus chloride ion channel could be effected that is controlled by ATP (Winstanley and Fothergill, 2008).
Iron is essential in all cells for converting oxygen and glucose into cellular energy (cellular respiration).
The liver breaks down glucose for energy; NA[D.sup.+] is an essential cofactor for the synthesis of adenosine triphosphate (ATP) during cellular respiration. Low levels of NA[D.sup.+] affect blood sugar balance and regulation by preventing normal cellular respiration, which impairs liver functions.
Most cancer cells continue to depend on glucose, but switch over from "cellular respiration" (which requires oxygen), to "glycolysis" (which can happen with or without oxygen).
These 34 compounds were further investigated in the tier-two assays, which included assays that (a) directly measure mitochondrial function by assessing MMP in HepG2 cells, rat primary hepatocytes, and human neural stem cells (hNSC); (b) measure production of reactive oxygen species (ROS) as an indicator of mitochondrial damage/dysfunction; (c) measure pathways related to mitochondrial dysfunction by assessing up-regulation of nuclear erythroid 2-related factor 2/antioxidant response element (Nrf2/ARE) in HepG2 cells and tumor protein (p53) in HCT116 cells; (d) assess mitochondrial function by measuring cellular respiration in isolated rat liver mitochondria and measuring Parkin translocation as an indicator of autophagy (Sun et al.
