What are the main Biomolecules (4)
Carbohydrates
Proteins
Lipids
Nucleic acids
Are linked to each to each other to form macromolecules (large molecules) of the cell ex. glucose to glycogen, amino acids to protein.
Form cells that comprise living matter
Biomolecules
STABILIZING FORCING IN MOLECULES
Formed by sharing of electrons between atoms.
A strong and the most common bond in living organisms.
Covalent Bonds
aka Electrostatic Bonds
Ionic Bonds
Positive end of one molecule is attracted to the negative end of another
Hydrogen Bonds
Provide the energy needed to sustain life
Biomolecular reactions
TYPES OF METABOLIC PATHWAYS
CATABOLIC AND ANABOLIC PATHWAYS
Degradation: where energy rich complex macromolecules (large molecules) are degraded into smaller molecules.
Catabolic pathways
Biosynthesis: cells synthesize complex molecules from simple precursors.
Anabolic Pathways
