The Chemical Context of Life
Campbell Biology: Third Canadian Edition
BIOL(108)
UOA
Detailed Overview:
1. Atomic Structure and Elements Essential to Life
-Basics of Atomic Structure: Review the structure of atoms, including protons, neutrons,
electrons, atomic number, and mass number. Understand how these components define an
element.
-Essential Elements of Life: Focus on Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N),
Phosphorus (P), Sulfur (S), and their importance in biological molecules.
2. Chemical Bonds: The Basis of Molecular Interactions
-Covalent Bonds: Understand how atoms share pairs of electrons in covalent bonds and
differentiate between nonpolar and polar covalent bonds.
-Ionic Bonds: Learn how atoms can donate or accept electrons, leading to the formation of ions
and ionic bonds between them.
-Hydrogen Bonds: Understand the significance of hydrogen bonds in water molecules and
between nucleotides in DNA.
-Weak Chemical Interactions: Recognize the role of van der Waals forces in the interaction
between molecules.
3. Water: The Solvent of Life
-Polarity and Properties: Comprehend how the polarity of water leads to its unique properties,
including cohesion, adhesion, surface tension, and its ability to dissolve various substances.
-Heat Capacity: Understand water's high specific heat and its implications for temperature
regulation in organisms and environments.
-Ice's Density: Know why ice floats on water and the importance of this phenomenon for aquatic
life.
4. Introduction to Carbon Compounds
- Carbon's Bonding Properties: Explore how carbon forms covalent bonds and the variety of
structures it can create, including chains, rings, and isomers.
