Steroids Are lipids, which are precursors to hormones and drugs
Proteins They are Polymers of 20 molecules called Amino Acids. Enzymes are a type of
protein, which catalyze different reactions or processes. LARGEST Biological
Molecule
Cell Fundamental unit of biology
Prokaryotic Cells NO defined nucleus and NO membrane- bound organelles.
Eukaryotic Cells Membrane-enclosed nucleus and series of membrane-bound organelles that
carry out the functions of the cell as directed by the genetic information
contained in the nucleus.
Nucleus Contains DNA called Chromosomes.
Ribosomes Are organelles that read the RNA produced in the nucleus and TRANSLATE the
genetic instructions to produce PROTEINS.
Bound ribosomes Are found attached to the endoplasmic reticulum (ER)
Free ribosomes Are found in the cytoplasm
Endoplasmic reticulum Attached to the nucleur membrane and consists of two continuous parts.

Rough ER Covered in RIBOSOMES and is responsible for PROTEIN SYNTHESIS and
membrane production.
Smooth ER NO ribosomes. It functions in the DETOXification and METABOLISM of multiple
molecules.
Golgi Apparatus Packaging, processing and shipping. "UPS"
Lysosomes Intracellular DIGESTION. hydrolyze proteins, fats, sugars, and nucleic acids.
Vacuoles uptake food through the cell membrane by phagocytosis. Plant cells have a
central vacuole that functions as storage, waste, disposal, protection, and
hydrolysis
Mitochondria Found in Eukaryotic cells and are the site of CELLULAR RESPIRATION
Cellular Respiration Formula C6H12O2 + 6O2 ------> 6CO2 + 6H20 + Energy (ATP)
Steps of Aerobic Cellular Respiration Glycolysis, Kreb's Cycle, Electron Chain Transport
Steps of Anaerobic Cellular Respiration Glycolysis and Fermentation
Asexual Reproduction (Mitosis) Produces 2 daughter cells. "Everything stays the same"
Sexual Reproduction (Meiosis) Produces 4 daughter cells 1/2 from mom 1/2 from Dad
Begin as diploid end as haploid
