Starch is a chain of glucose. Cellulose is made of multiple chains of glucose with hydrogen bonding to connect the chains. The G Thingsglycerol (lipids) | ALL fatty acids | glycogen (polysaccharide) | Jenna needs energy, made of glucose | glucagon (protein) | sugar in the blood is GONE |
Endosymbiont theoryMitochondria and chloroplasts were formerly small prokaryotes that began living within larger cells, may have gained entry as undigested prey or parasites. In a world that was increasingly aerobic, host benefited from endosymbiont that could use oxygen to create energy. This led to the formation of a eukaryotic cell with a mitochondria. Plant cells were developed from eukaryotic cells with photosynthetic prokaryote. |
Structural ProteinWhat structural protein is secreted outside of cells making up 40% of the protein in your body? collagen |
DiabetesType 1 | insulin isn't produced, beta pancreatic cells damaged | Type 2 | insulin/glucose receptors not working |
Hyperglycemia (high blood sugar), hypoglycemia (low blood sugar). Antagonist to insulin is glucagon. Tonic SolutionsConvert all %s to describe solvent, think about concentration gradient of solvent. |
Hypertonic - full of things
Hypotonic - empty of things Membrane TransportWhat kind of materials can travel through membrane passively? Non-polar molecules and water. |
Steroid HormonesWhy can steroid hormones pass through membranes? non-polar |
PhosphorylationPhosphorylation is the transfer of a phosphate from ATP to another molecule. |

Community is a bunch of populations, ecosystem is those populations and abiotic factors. Lipidsmonomer | fatty acids, glycerol | polymer | none | purpose | long-term energy storage | ETC | hydrophobic |
Saturated fats are found in animals, unsaturated found in plants and is healthier. Trans fat is structured like a unsaturated fat, but straightened like a saturated fat.
Head of phospholipid is hydrophilic, tail hydrophilic. Fats are more concentrated amounts of energy than carbohydrates. Proteinsmonomer | amino acids (different R groups) | polymer | polypeptide, enzyme | bonded by | peptide bonds | ETC | shape determines function |
Destroyed via denaturation. Must be in specific temp and pH. Protein Structureprimary | chain (covalent bonds) | secondary | alpha helix, beta sheet (hydrogen bonds) | tertiary | 3D shape | quarternary | multiple chains |
LysosomesDigestion, disposal and recycling of material. Malfunction can result in Tay-Sachs disease. |

Water/Lipid-Soluble Hormone Signaling
EnzymeEnzymes are selective in the reaction it catalyzes. It can be a protein or RNA. The specific reactant it acts on is the substrate, which fits into the active site on the enzyme. Cofactors are helps that bind to the active site and function in catalysis. Coenzymes are organic cofactors. This speeds up reactions. |
Competitive inhibitors block the active site whereas noncompetitive inhibitors reshape the enzyme. Cellular Respirationglycolysis | cytoplasm, 2 net ATP | pyruvate oxidation | 0 ATP | citric acid cycle | matrix, 2 ATP | oxidative phosphorylation | inner mitochondrial membrane, ~28 ATP |

Theory, Hypothesis, LawTheory - widely accepted explanatory idea that is supported by a body of evidence | Hypothesis - testable explanation for a set of observations based on the available data | Law - statement based on repeated experimental observations that describes some aspect of the universe |
Law describes, theory and hypothesis explain. ReasoningDeductive: general --> specific | Inductive: specific --> general |
Sherlock utilizes inductive reasoning. He's in the "in" and knows the details. Nucleic Acidsmonomer | nucleotides | polymer | nucleic acids, DNA, RNA | bonded by | hydrogen bonds (form helix), covalent bonds (form backbone) | purpose | genetic info |
Nucleuscontains genetic information, DNA | direct protein synthesis, controlling cell's acticities | chromatin - complex of proteins and DNA | nuclear envelope - double membrane enclosing nucleus | nucleolus - where rRNA is synthesized |

AquaporinsWhat if a cell has too many aquaporins? Too much water will be absorbed, body tissues will swell. |
Exocytosis & Endocytosis
Types of EndocytosisPhagocytosis takes in large molecules, taking them to lysosome via vacuole. Receptor-mediated endocytosis takes in specific solutes, forming a vacuole and then releasing the solute into cytoplasm. |
