Biochemistry is the study of biomolecules natural compounds living molecules( biomolecules, natural compounds, living molecules ) and the chemical reactions that occur in living organisms a closed system an environment( living organisms, a closed system, an environment ).
Biomolecules are...
proteins
carbohydrates
nucleic acids
lipids
fatty acids
nucleic bases
cholesterols
Chemical reactions are either endergonic or exergonic
❌ reaction: requires absorption of energy; products have ❌ free energy than reactants
❌ reaction: releases energy; products have ❌ free energy than reactants
Living matter is characterized by...
A high degree of complexity and organization
The extraction, transformaation, and systematic use of energy to ceate and maintain structures and to do work
the interactions of individual components being dynamic and coordinated
the ability to sense and respond to changes in surroundings
the capacity for fairly precise self-replication while allowing enough change for evolution
the formation of organized organs and organelles
