Expert writing Tips
Best practice
When describing scientific processes, use "upon receptor" to indicate that a specific event immediately follows receptor activation or binding. However, consider simpler alternatives like "after" or "following" for clearer communication.
Common error
While "upon receptor" is acceptable in scientific contexts, avoid overusing "upon" in general writing. It can sound overly formal or archaic. Opt for more common prepositions like "on", "after", or "when" for improved clarity.

Ludwig's WRAP-UP
The phrase "upon receptor" is a prepositional phrase primarily used in scientific and technical writing to indicate that an event occurs immediately after receptor activation or binding. While grammatically acceptable, Ludwig AI notes it may sound somewhat formal or awkward in general English; simpler alternatives like "after" or "following" might be preferred in less formal contexts. The phrase's high frequency within scientific literature underscores its utility in clearly establishing cause-and-effect relationships in biological processes. Therefore, reserve its usage for relevant scientific contexts and prefer simpler alternatives if clarity or conciseness are more important.

Phrases that express similar concepts, ordered by semantic similarity:
after receptor activation
Indicates the timing of an event in relation to when the receptor has been activated. Provides a more straightforward temporal indicator.
following receptor binding
Specifies that the subsequent action occurs directly after the receptor binds to its ligand. It emphasizes the binding event as the trigger.
subsequent to receptor stimulation
Emphasizes that the event comes after the receptor has been stimulated. Implies a sequence of events.
in response to receptor activation
Highlights that the event is a direct reaction or consequence of the receptor's activation. Focuses on the cause-and-effect relationship.
with receptor engagement
Similar to 'upon', but focuses on the interaction of a receptor with its binding partner. Suggests a more direct interaction.
when the receptor is activated
Clearly states the condition under which the event occurs. Avoids the slightly more formal tone of "upon".
on receptor stimulation
Uses "on" as a more concise alternative to "upon", while maintaining the meaning related to receptor activity.
as a result of receptor activation
States that the event occurs directly due to receptor activation. Emphasizes the causal relationship.
due to receptor binding
Highlights receptor binding as the cause of the subsequent event. Implies a direct consequence.
triggered by receptor engagement
Specifies that the receptor's engagement acts as the trigger for a series of events. Emphasizes the initiation of a process.
FAQs
How can I use "upon receptor" in a sentence?
Use "upon receptor" to indicate that something happens immediately after a receptor is activated or binds to a ligand. For example, "Upon receptor activation, the signal is transmitted intracellularly."
What are some alternatives to "upon receptor"?
Alternatives include "after receptor activation", "following receptor binding", or "in response to receptor stimulation". Choose the alternative that best fits the specific context.
Is "upon receptor" formal or informal language?
"Upon receptor" leans towards formal language, particularly within scientific writing. Simpler alternatives might be more appropriate in informal contexts.
Is it always necessary to use "upon receptor", or can I use "on receptor"?
