Chapter 2 - Chemistry of Life
Structure Of Matter
Subtopic A - Elements of life
Definition: Basic substances that cannot be broken down
Detail: 96% of living matter = C, H, O, N
Example: Carbon in carbohydrates
Subtopic B - Atoms
Detail: Protons (+), Neutrons (0), Electrons (-)
Definition: Smallest unit of an element
Example: Hydrogen atom
Subtopic C - Chemical Bonds
Detail: Involves sharing or transferring electrons
Example: Bond between H and O in water
Properties of Water
Subtopic D - Water Properties
Function: Supports life
Detail: Cohesion & adhesion
Example: Water transport in plants
Subtopic E - pH Scale
Definition: Measures acidity/basicity (0-14)
Detail: pH 7 = neutral
Example: Stomach acid (pH~2)
Function: Affects enzyme activity
Chemical Reactions in Living Systems
Subtopic G- Acids and Bases
Type 1: Acid (donates H+)
Type 2: Base (accepts H+)
Type 3: Neutral
Example: HCI = acid
Explanation: Regulate pH in living systems
Subtopic F- Solutions
Definition: Homogenous mixture
Further Detail: Solute + Solvent
Example: Salt water
Subtopic 1: Carbon-Based Molecules
Subtopic 1- Molecular Diversity of Carbon
Example: Glucose
Explanation: Allows complex molecules
Explanation: Carbon forms 4 bonds
Definition: Organic molecules containing carbon
Detail: Backbone of biological macromolecules
Example: Carbohydrates, nucleic
