Inorganic Constituents of Living Tissue
Lists the common inorganic compounds and ions found in living organisms, emphasizing their presence and importance as identified through various analytical methods.
What is Inorganic Constituents of Living Tissue?
Mineral elements and compounds found in living tissues that are not primarily based on carbon chains, such as water, ions, and salts.
Key points
- Identify the major and minor inorganic constituents of living tissues.
- Explain the importance of water as an inorganic component.
- Describe the roles of key inorganic ions (cations and anions) in biological processes.
- Understand the significance of trace elements in physiological functions.
Common exam trap
Confusing the role of organic and inorganic compounds.

Wet Ashing
- Meaning
A laboratory technique used to remove organic matter from a sample by treating it with oxidizing acids, leaving behind inorganic residues for analysis.
- Term
Trace Elements
- Meaning
Chemical elements required in very small amounts by living organisms for proper growth and metabolism, but are essential for life.
- Term
Homeostasis
- Meaning
The tendency of an organism or cell to regulate its internal conditions, such as temperature or pH, to maintain a stable, constant state.
