Term: Calcium Ion

Description: A calcium ion is a charged particle or atom of calcium that has lost or gained electrons, resulting in a positive charge. Calcium ions play a crucial role in various biological processes and are involved in muscle contraction, nerve signaling, and bone health.

Senses:

1. In Chemistry: Calcium ion refers to the positively charged calcium atom (Ca²⁺) that forms when calcium loses two electrons. It is highly reactive and plays a vital role in chemical reactions and as a catalyst.
2. In Biology: Calcium ion refers to the free, charged form of calcium (Ca²⁺) found in biological systems. It functions as a secondary messenger in cell signaling, contributing to muscle contractions, nerve impulses, and enzyme regulation.

Sample Sentences:

• Chemistry: The addition of calcium ions to the solution resulted in a rapid precipitate formation.
• Chemistry: The fluorescence intensity of the solution increased upon the introduction of calcium ions.
• Biology: Calcium ions play a vital role in muscle contraction and relaxation.
• Biology: The release of calcium ions triggers the fusion of synaptic vesicles and neurotransmitter release in neurons.
