Without insulin, glucose cannot enter into the cells, and builds up in the blood stream (this is also called Diabetes!) Once in the cell, your body uses glucose for a host of things, including the Krebs cycle, in order to metabolize products and create energy. Source(s): I am an RN. Alexandra W Â· 7 years ago.
A sensor is a device that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena.The output is generally a signal that is converted to human-readable display at the sensor location or transmitted electronically over a network for reading or further processing.he liquid contained expands and contracts in response, causing the level to be higher or lower on the marked gauge, which is human-readable. An oxygen sensor in a car's emission control system detects the gasoline/oxygen ratio, usually through a chemical reaction that generates a voltage.
The TPS sensor is a potentiometer type of electrical component. Rather than just being opened or closed like a switch, the TPS controls the circuit by varying its resistance in response to throttle position. In most cases this sensor will send a very low voltage back to the vehicle's main computer when the throttle plates are fully closed. This reference voltage rises as the throttle opens to increase speed. Keep in mind that some manufacturers use inverse voltage readings for feedback.
