3. Water All life, and therefore biology , occurs in water.
4. Properties of Wa- 2 Hydrogen bonds Covalently bonded to Oxygen.
ter
Hydrogen Bonding between molecules.
- High specific heat
- Large bodies or water stabilize climates
- Strong cohesive and adhesive properties
- Water freezes forms a lattice crystal resulting in ice
floating in water.
- Polarity of water allows it to act as a universal solvent.
- Water can be used to dissolve different solvents.
5. Carbohydrates Long chains, or polymers of sugar. Most importantly form
the backbone of DNA and RNA.
6. Saturated Clogs arteries. NO DOUBLE BONDS in their hydrocarbon
tail. SOLID @ room temperature.
7. Unsaturated Double bond in their hydrocarbon tail. LIQUID at room
temperature.
8. Phospholipids Phosphate group (polar) soluble in water. Hydrocarbon
tail of fatty acids is nonpolar and nonsoluble in water.
Ex. Cell Membrane
, Hesi A2 Biology Exam
9. Steroids Are lipids, which are precursors to hormones and drugs
10. 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
11. Cell Fundamental unit of biology
12. Prokaryotic Cells NO defined nucleus and NO membrane- bound or-
ganelles.
13. Eukaryotic Cells Membrane-enclosed nucleus and series of mem-
brane-bound organelles that carry out the functions of the
cell as directed by the genetic information contained in
the nucleus.
14. Nucleus Contains DNA called Chromosomes.
15. Ribosomes Are organelles that read the RNA produced in the nucle-
us and TRANSLATE the genetic instructions to produce
PROTEINS.
16. Bound ribo- Are found attached to the endoplasmic reticulum (ER)
somes
17. Free ribosomes Are found in the cytoplasm

18. Endoplasmic Attached to the nucleur membrane and consists of two
reticulum continuous parts.
19. Rough ER Covered in RIBOSOMES and is responsible for PROTEIN
SYNTHESIS and membrane production.
20. Smooth ER NO ribosomes. It functions in the DETOXification and
METABOLISM of multiple molecules.
21. Golgi Apparatus Packaging, processing and shipping. "UPS"
22. Lysosomes Intracellular DIGESTION. hydrolyze proteins, fats, sug-
ars, and nucleic acids.
23. Vacuoles uptake food through the cell membrane by phagocytosis.
Plant cells have a central vacuole that functions as stor-
age, waste, disposal, protection, and hydrolysis
