receptor
In biology and medicine, a specialized cell or molecule that reacts to certain stimuli such as light, pressure, or chemical substances and passes on a signal. Receptors are crucial for sensory perception and communication between cells.
Die Schmerzrezeptoren in der Haut senden bei einer Verletzung ein Signal an das Gehirn.
The pain receptors in the skin send a signal to the brain when there is an injury.
'Rezeptor' (receptor) is a technical term from biology, chemistry, and medicine. This word is rarely used in normal everyday life.
In der Vorlesung haben wir über die Funktion von Neurotransmittern und ihren Rezeptoren gesprochen.
In the lecture, we talked about the function of neurotransmitters and their receptors.
The word is derived from the Latin verb 'recipere', which means 'to take in' or 'to receive'. A receptor is therefore literally a 'receiver' for certain signals or substances.
Jeder Rezeptor ist für einen bestimmten Botenstoff spezialisiert.
Each receptor is specialized for a specific messenger substance.
To describe what a receptor is specialized for, you use the preposition 'für' (for) followed by the accusative.
Die Zunge hat verschiedene Rezeptoren für süße, saure, salzige und bittere Geschmäcker.
The tongue has different receptors for sweet, sour, salty, and bitter tastes.
recipient / receiver
'der Empfänger' and 'der Rezeptor' can both receive something, but they belong to different fields. An 'Empfänger' is often a technical device that receives signals and makes them usable. A 'Rezeptor' is a biological or medical term for a cell or molecule that responds to a stimulus and passes on a signal. The words can be confused because both receive a kind of signal. In technology, you are more likely to say 'Empfänger'; for the body, cells, and sensory perception, 'Rezeptor' is more common.
Ein Rezeptor in der Haut reagiert auf Druck und Wärme.
A receptor in the skin reacts to pressure and heat.
Der Empfänger im Radio nimmt das Signal nur schwach auf.
The receiver in the radio picks up the signal only weakly.
