cellular respiration

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

cellular respiration

or

cell respiration

a catabolic process (see CATABOLISM) occurring in cells where complex organic molecules are broken down to release energy for other cellular processes. Cell respiration usually occurs in the presence of oxygen (see AEROBIC RESPIRATION) but some organisms can respire without oxygen (see ANAEROBIC RESPIRATION).

The rate of oxidative metabolism was 21-fold higher compared with the rate of nonoxidative metabolism (Haber et al.
There is also a 15%-20% decrease in oxidative metabolism between young and old adults in drugs that use the cytochrome P450 system for oxidization and inactivation.
SPECT and PET tracers have been developed to measure oxidative metabolism, fatty acid and amino acid metabolism, and pre- and post-synaptic receptor densities.
It has been hypothesized that this is due to inefficient oxidative metabolism in the limbic system and brainstem where the control mechanisms dominate.
A group of 33 dogs undergoing openchest left anterior descending coronary artery (LAD) ligation causing prolonged ischemia were imaged with quantitative positron emission tomography (PET) using 2-[18F]fluoro-2-deoxy-D-glucose (18FDG) to measure regional glucose metabolic utilization (rGMU) and [11C]acetate to measure regional monoexponential washout rate constant (Kmono) for oxidative metabolism in nonrisk and ischemic-risk myocardium.
Environmental oxidative stress can also involve the depletion of cellular antioxidant defense mechanisms or dysregulation of oxidative metabolism processes in the cell (Ercal et al.
As shown in Figure 1, ADH, cytochrome P450 2E1 (CYP2E1), and catalase all contribute to oxidative metabolism of ethanol.
CYP 1A2 is the principle isoenzyme involved in the initial oxidative metabolism of riluzole.
For more than 80 years it has been known that cancer cells generate their energy principally by glycolytic metabolism rather than by oxidative metabolism, the latter being the primary energy source in healthy cells.
GLA is further metabolized to dihomogamma linlenic acid (DGLA) which undergoes oxidative metabolism by cyclooxygenases and lipoxygenases to produce anti-inflammatory eicosanoids (prostaglandins of series 1 and leukotrienes of series 3).
