5' AMP-activated protein kinase or AMPK or 5' adenosine monophosphate-activated protein kinase is an enzyme (EC 2.7.11.31) that plays a role in cellular energy homeostasis, largely to activate glucose and fatty acid uptake and oxidation when cellular energy is low.
AMPK is a cellular energy sensor conserved in all eukaryotic cells. The kinase activity of AMPK is activated by the stimuli that increase the cellular AMP/ATP ratio. AMPK regulates the activities of a number of key metabolic enzymes through phosphorylation. It protects cells from stresses that cause ATP depletion by switching off ATP-consuming ...
Traffic signal preemption (also called traffic signal prioritisation) is a system that allows an operator to override the normal operation of traffic lights.The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety.
AMPK may refer to: AMP-activated protein kinase, an enzyme (acetyl-CoA carboxylase) kinase, an enzyme This page was last edited on 15 May 2022, at ...
A daytime running lamp (DRL, also daytime running light) is an automotive lighting and bicycle lighting device on the front of a road going motor vehicle or bicycle. [1] It is automatically switched on when the vehicle's handbrake has been pulled down, when the vehicle is in gear , or when the engine is started, emitting white, yellow , or ...
NWAS ambulance displays the operation of a wig-wag: only one headlight operates at a time, with the two flashing alternately at a preset rate.. A wig-wag is a device for flashing an automobile's headlamps, in its simplest form, so only one of the two headlights operates at a time, with the two flashing at a preset rate.
A truck with a bucket-like cargo area which the front can be raised, hinging on the rear, allowing the load to slide ("dump") out of the cargo area. Often a straight truck, semi-trailers are also common. Flatbeds and refuse container trucks can often "dump", but are rarely called that. [3] Eighteen-wheeler
Some traffic lights in Pennsylvania illuminate the yellow light a few seconds before the green light turns off, to give this same warning, [citation needed] as did some lights in the Los Angeles area until at least the late 1970s, and one light in Glendale, AZ at 56th Avenue &Glenn until it was replaced in the early 1980s. Traffic lights in ...
