Life Functions Flashcards
Release of energy by oxidation of food
Respiration
Absorption of nutrients
Assimilation
Maintaining stability of organism’s chemical makeup under constantly changing internal and external environment or homeostasis
Regulation
Building up of complex molecules from simple compounds
Synthesis
Response to stimuli
Irritability
The ability to change position
Movement
Production of internal light within some organisms
Bioluminescence
The movement of materials into and out of the various cells and tissues of organisms
Transportation
The process by which nutrients and simple molecules are used to form more complex molecules for growth, repair, and reproduction
Anabolism
To provide small molecules such as simple sugars and amino acids as building blocks for more complex molecules
Anabolism
The process of breaking down complex molecules to release energy from chemical bonds
Catabolism
Taking in food
Ingestion
A special form of catabolism that breaks down food into smaller molecules and releases energy
Digestion
Formation of useful substances
Secretion
Allow small molecules to pass through cell membranes throughout the body tissues
Absorption
