| 6218040205 | 4 Organic Molecules | Carbohydrates, lipids, proteins, nucleic acids | | 1 |
| 6218044661 | Carbohydrates | Means carbon and water. (carbon:2hydrogen:oxygen) General functions include energy and structure. Found in foods such as grains, fruits, vegetables, and anything sweetened with sugar. When someone consumes more carbs than they need, they are stored as energy (glycogen) in the liver. Classified based on complexity: monosaccharides, disaccharides, polysaccharides. | | 2 |
| 6218077053 | Monosaccharides | Simple sugars, water soluble. Useful as an energy source because they can be quickly metabolized/transported. Most common include glucose, fructose, and galactose. | | 3 |
| 6218083797 | Glucose | Made by plants in photosynthesis to produce cellular energy. Primary metabolic fuel for humans (circulates in blood). Given by IV for those who cannot eat. |  | 4 |

| 6218181536 | Chitin | Found in insect/lobster exoskeletons. Provides strength/support/waterproofing. | | 16 |
| 6218193865 | Cellulose | Found in the cell walls of plants for strength and structural support. | | 17 |
| 6218201756 | Dehydration Synthesis | An anabolic reaction. Involves the REMOVAL of water to build a new, larger compound. Living things use this process to build the larger molecules they need for things like growth and repair. ex. glucose+glucose=maltose+water | | 18 |

Four main groups: triglycerides, waxes, phospholipids, steroids. | | 20 |
| 6218257174 | Triglycerides | Fats and oils. Contain 2X more energy than carbs, making a great energy source but easy to consume in excess (not good). No more than 30% of calories should come from these. Excess is stored in the body as adipose tissue. Important to regulate body temperature/cushion organs.

| 6218698634 | Waxes | One fatty acid chain bonded to an alcohol group. Do not dissolve in water (waterproofing), plants have waxes as protective covering on their steams and leaves to prevent water loss. | | 31 |
| 6218718549 | Phospholipids | Two fatty acid chains bonded to a glycerol plus phosphorus. Main structural components of cell membranes (selectively permeable). | | 32 |
| 6218739772 | Steroids | Structurally different from other lipids. Carbon skeletons that do not contain fatty acids. Most common is cholesterol, needed to make hormones, bile, and a component of cell membranes. | | 33 |
| 6218781082 | HDL cholesterol | Having high levels in the blood is considered good. Low levels in the blood is linked to heart disease. Does not stick to blood vessels and cleans LDL cholesterol from the blood. | | 34 |
| 6218892919 | LDL cholesterol | Having low levels in the blood is healthy. High levels in the blood is linked to heart disease. Can cause atherosclerosis. | | 35 |
| 6218912454 | Atherosclerosis | When cholesterol molecules stick to the walls of blood vessels and form plaque deposits. This causes the vessels to narrow and form blood clots, eventually becoming blocked and causing heart attack, stroke, and gangrene. | | 36 |
| 6218936315 | Key to a Healthy Diet | Limit fat intake to 25-35% of calories in a day. <7% from saturated fats, rest from healthy unsaturated fats. Trans fats should not exceed 1%. | | 37 |

Form structures like hair and muscles, pigments like hemoglobin and melanin, hormones like insulin and adrenaline, enzymes like maltase and lactase, antibodies, and energy as a last resort. Globular or fibrous. Made up of subunits called amino acids. | | 38 |
| 6222358157 | Amino Acids | Approximately twenty different versions. Eight are essential and must be consumed. Animal proteins contain all eight but plant proteins do not. | | 39 |

| 6226659318 | Energy Transfer Nucleic Acids | ATP (adenosine triphosphate), ADP (adenosine diphosphate), AMP (adenosine monophosphate). When a cell stores energy, it does so by bonding phosphates together. ATP is created during cellular respiration when a cell converts food and oxygen into CO2 and water. When a cell uses energy, ATP/ADP is released due to the bonds between phosphates being broken. |  | 52 |
| 6226689065 | Water | Polar molecule. Facilitates chemical reactions in the human body and helps oxygen and nutrients enter cells (solvent). Helps maintain the body's internal temperature. The body loses this through sweat, urine, and exhalation so replenishing throughout the day is essential. | | 53 |

| 6226736254 | Enzymes | Proteins that control chemical reactions in cells of living things. Biological catalysts. Lowers activation energy by bringing substrates close together. Named after the substrate they act upon ("-ase"). Reactions can be either synthesis or decomposition. "Lock-and-key" theory explains that certain ones can only facilitate one or two types of reactions. Can be reused. |  | 56 |

| 6226809902 | Factors that affect enzyme action | Temperature (optimum, when it goes beyond a certain point the enzyme can denature), pH (optimum), concentration, coenzymes/cofactors, competition of inhibitors | | 64 |
| 6226814559 | Coenzymes/Cofactors | Non-protein substances (vitamins and minerals) that are required by some enzymes to work on the substrates. They activate the enzyme by changing its shape/molding it to fit the substrate. | | 65 |
| 6226819130 | Competitors | Chemicals that are similar in structure to substrates that can bind to an active site, preventing the necessary substrate from binding and therefore slowing down or stopping the chemical reaction. | | 66 |
