Practice question
Question
Given below are two statements : Statement I : The difference in carbon dioxide equilibrium curve for oxygenated and deoxygenated blood is called as Haldane effect. Statement II : Detection of ingested chemical is known as gustation and a G-protein coupled receptor involved in the sense of taste that detects sweet tastants is known as metaducin. In the light of the above statements, choose the correct answer from the options given below :
Explanation
Haldane effect describes greater CO2 carrying capacity of deoxygenated blood versus oxygenated blood, shifting CO2 dissociation curve. Gustation indeed detects ingested chemicals, but sweet taste receptor uses gustducin, not metaducin, rendering second statement incorrect regarding transduction protein nomenclature.
