| Question/Term | Answer |
|---|---|
| Waters effect for the human body... | Fill blood vessels and move dissolved molecules throughout the body Has a slight charge allowing reactions to occur Often loses a Hydrogen |
| Hydrophillic? | Water LOVING(vinegar/salt |
| Hydrophobic? | Water HATING(oil) |
| pH? | Measurement of how ACIDIC or BASIC a solution is(H+ is measured) |
| Basic(OH-) Solution? | 8-14(most basic) |
| Acidic(H+) Solution? | 0-6(most acidic) |
| 7 on pH scale? | Neutral |
| Enzymes(key)? | A PROTEIN that SPEEDS up RATE of CHEMICAL REACTION in a LIVING organism(does not change due to reaction) |
| Substrate(door)? | MOLECULE in which the Enzyme REACTS |
| Macro-nutrients? | Provide ENERGY 1 Carbohydrates 2 Protein 3 Fats, Lipids |
| Micro-nutrients? | Contain NO ENERGY, proper GROWTH/FUNCTION 1 Vitamins 2 Minerals 3 Water |
| All diseases begin with... | MUTATION of a SINGLE CELL |
| Prokaryotic? | NO nucleus(BACTERIA) |
| Eukaryotic? | NUCLEUS and ORGANNELLES |
| Plasma Membrane? | Where the EXCHANGE between CELL and ENVIRONMENT occur(Nutrients IN/Waste OUT) |
| Volume(cell)? | Determines how many nutrients are needed and how much waste is produced |
| As cell size increases... | Volume increases FASTER than Surface area |
| In Eukaryotic cell, cell membrane is made up of... | PHOSPHOLIPIDS |
| Head of Phospholipid is... | Hydrophillic |
| Tail of Phospholipid is... | Hydrophobic(head must protect tails) |
| Phospholipids? | Semipermeable, SELECTIVELY allows the passage of NUTRIENTS INTO the cell and WASTE OUT |
| Factors that influence permeability(3)... | Smaller mol pass through easier Ions are LESS permeable Water and Gases pass through easier |
| Cytoplasm? | Any fluid within plasma membrane(aqueous interior) |
| Organelle(s)? | Small structures suspended in Cytoplasm having a specific function |
| Nucleus? | Houses genetic material(DNA) "Blue Print" |
| Nucleolus? | Produces ribosomes |
| Mitochondria? | Energy production(ATP) |
| Smooth Endoplasmic Reticulum(ER)? | Produces lipid molecules, bile and cholesterol Adds OH- to petroleum products(pesticides) turning it hydrophilic |
| Rough Endoplasmic Reticulum(ER)? | Ribosomes/Protein Production |
| Golgi apparatus? | Packages and SECRETES to outside of cell |
| Lysosome? | Break down Foreign Material and dying Organelles as well as cell self distruction |
| Cytoskeleton? | Maintains shape and assists movement of cell parts |
| Tissue? | Cells of the SAME type that perform a common function in the body |
| Connective Tissue? | Binds and supports body parts(bone, blood..) |
| Muscular Tissue? | Move the body and its parts |
| Nervous Tissue? | Receives stimuli and conducts nerve impulses |
| Epithelial? | Covers body surface and lines body cavities |
| Organ? | TWO or more TYPES of TISSUE working TOGETHER to perform a function(unique and irreplaceable) |
