Study Notes

Unit 4: How to Maintain a Stable Existence?

Biological systems function due to emergent properties arising from hierarchical structures within organisms.
Living things use a limited set of elements to create building blocks and support life through transferring matter and energy.
Multicellular organisms are made of hierarchical parts.
Biological macromolecules like proteins, carbohydrates, and fats are composed of specific elements.
Organisms obtain the elements needed to build these molecules through various processes.
Carbon's unique structure makes it vital, especially within living organisms.

Hierarchical Organization of Organisms

Living organisms are organized in a hierarchical manner, from atoms to biosphere.
Hierarchical structure encompasses cells, tissues, organs, organ systems, and the organism itself.
This organization allows specialization and complex functions.
Non-living components are excluded from this organizational model.
Interconnected systems carry out different functions via specialized systems (like circulatory system).

Macromolecules

Atoms bond in predictable ways to form molecules making up macromolecules.
Key molecules include carbohydrates (sugars), lipids (fats), proteins, and nucleic acids.
These molecules are composed of specific chemical elements (C, H, O, N, S, P).
Macromolecules form the basis of all living organisms.

Elementary Composition and Emergent Properties

A limited number of atoms (carbon, hydrogen, oxygen, and nitrogen – CHON) form all living organisms.
Emergent properties result from interactions among different components of a system, creating functions that individual parts don't possess..
