Study Notes
Defining Living Things
- Living things can be defined by size, appearance, complexity, and genetic material.
Seven Characteristics of Living Organisms
- Movement: Action by an organism or part of it, causing a change of position.
- Respiration: Chemical reactions breaking down nutrient molecules in living cells to release energy.
- Sensitivity: Ability to detect changes in the environment (stimuli) and make responses.
- Growth: A permanent increase in size and dry mass through an increase in cell number, cell size, or both.
- Reproduction: Processes to make more of the same organism type.
- Excretion: Removal of toxic materials, waste products of metabolism, and excess substances.
- Nutrition: Consuming nutrients, organic substances, and mineral ions with raw materials or energy for growth and tissue repair.
Levels of Organization of Biological Study
- Atoms
- Molecule
- Cell
- Tissue
- Organ
- Body system
- Organism
- Population
- Community
- Ecosystem
- Biosphere
Biomolecules
- Molecules are made of biological elements that constitute all living things
- There are four types of biomolecules: carbohydrates, lipids, nucleic acids, and proteins.
- Monomers are the basic building blocks and repeating units of biomolecules.
- Polymers are whole biomolecules made of monomers.
Carbohydrates
- Structure:
- Monomers: Monosaccharides like glucose and fructose.
- Polymers: Polysaccharides (complex carbs) like starch and wheat.
- Function:
- Monosaccharides: Offer cells a quick burst of short-term energy.
- Polysaccharides: Offer cells more intermediate energy.
Lipids
- Structure:
- Monomers: Fatty acids and glycerol molecules.
- Polymers: Phospholipids, oils, and fats.
- Function:
- Phospholipids: They form the outer covering (cell membranes) of cells.
- Oils and Fats: Offer cells a source of long-term energy storage.
Nucleic Acids
- Structure:
- Monomers: Nucleotides.
- Polymers: DNA and RNA.
- Function:
- Provide cells with genetic instructions to make proteins.
Proteins
- Structure:
- Monomers: Amino acids.
- Polymers: Proteins and polypeptides, as well as enzymes.
- Function:
- They create cell structure.
- Provide the physical components/expression of DNA/RNA
- Enzymes catalyze (speed up) chemical reactions.
Hemoglobin
- A protein in red blood cells allows oxygen to bind.
- Contains iron in the center of the molecule.
