Which of the following best describes the function of biosensors?

The function of biosensors is best described as combining biological components with detectors for the detection of specific substances. This integration allows biosensors to convert a biological response into an electrical signal, enabling the identification and quantification of various analytes. The biological element, which could be enzymes, antibodies, or cells, interacts with the target substance, prompting a measurable signal generated by a transducer. This process is crucial in various applications, including medical diagnostics, environmental monitoring, and food safety, as it provides rapid and sensitive detection of biomolecules or pathogens.

The other options, while they encompass aspects related to biology or environmental science, do not accurately define the primary function of biosensors. Creating new biological organisms is more related to biotechnology and genetic engineering rather than the function of a biosensor. Monitoring environmental conditions may utilize biosensors, but it is too broad and does not encapsulate the essence of their operation. Enhancing cellular respiration pertains to cellular metabolism and physiology, which does not relate directly to the detection of substances in the context of biosensors.
