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.
Oxygen sensor. An oxygen sensor (or lambda sensor) is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. GÃ¼nter Bauman.
