Have you heard about phosphorylation in biology class?

Yeah, I think it has something to do with transferring phosphate groups, right?

Exactly! It's crucial in many metabolic processes.

I find it fascinating how enzymes can speed up phosphorylation reactions.

Synonyms & Antonyms

Root Explanation

Phosphorylation → It is formed from "phosphor" (from Greek "phosphoros", meaning light-bringer or phosphorus) and "-ylation" (a suffix used in chemistry to indicate the introduction of a group). The word refers to the process of adding a phosphate group to a molecule, often in biological contexts.

Memory Tip

Think of 'phosphor' as the 'light-bringer' and remember that 'phosphorylation' means adding a phosphate group, which can be crucial in energy transfer and signaling in cells.
