CO metabolism, sensing, and signaling

CO sensors act as signal transducers by coupling a "regulatory" heme-binding domain to a "functional" signal transmitter. Although high CO concentrations inhibit generally heme-protein actions, low CO levels can influence several signaling pathways, including those regulated by soluble guanylate cyclase and/or mitogen-activated protein kinases. This review summarizes recent insights into CO ...

Understanding Metabolic Flexibility + Exactly How To ...

By using a special CO2 sensor and flow meter, Lumen is able to determine exactly what fuel your body is using to produce energy by measuring the CO2 concentration in your breath - the higher your CO2, the more carbs you are burning and the lower your CO2 the more fat you are burning. Founded by Ironman competitors and PHD’s in nutrition Michal and Merav Mor, it’s the first metabolism ...

How does an NDIR CO2 Sensor Work? |

Today's newest generation of CO2 sensors has even more optimized waveguides, allowing a longer optical light path to be folded into an even smaller. 8 mm x 33 mm x 20 mm footprint. In addition to a smaller size, new mid-range infrared light-emitting diode (LED) light sources have been developed that allow NDIR sensors to operate at much lower power levels. Combined with a photo-diode light ...

· · In Everglades ecosystems, the use of CO 2 from the carbonate cycle by aquatic vegetation (Allen and Spence 1981; Maberly and Spence 1983) may be causing a weakening of the relationship between aquatic metabolism and ecosystem metabolism which argues for more studies in this area. Continuous measurements of calcium carbonate production and dissolution in the long …

sAC as a metabolic pH sensor - Cell

· · Perhaps most significantly, metabolic processes also result in changes in CO 2 production. Because of the equilibrium between CO 2, HCO 3 − and H + inside the cell, changes in [CO 2] i would cause [HCO 3 −] i to change in the same direction and would thereby affect sAC activity ( sAC would behave as a CO 2 sensor inside cells). This review will explore the potential for sAC to function as a metabolic sensor.

sAC as a metabolic pH sensor - Cell

· Cyclic AMP (cAMP) is an evolutionarily conserved regulator of metabolism. Recently, we identified a novel mammalian source of cAMP – soluble adenylyl cyclase (sAC) – that is regulated directly by bicarbonate ions (HCO3−). As the concentration of HCO3− reflects cellular levels of carbon dioxide (CO2), energy-generating metabolic processes (which increase intracellular CO2) are poised to ...

Using CO2Meter’s iSense CO2 and Oxygen Monitor and Data Logger, the team was able to accurately measure the absolute rates of O2 uptake and CO2 synthesis in yeast cells as they both respire and ferment simultaneously. The data lead to the discovery that cell metabolism and physiology can vary, even as growth rates remains constant.
