Question | Answer |
---|---|
Phosphodiester Bond | DNA, bond that forms between the phosphate of one nucleotide monomer to the sugar of an adjacent nucleotide monomer in the process of forming a polymer |
Surfactant | Substance that dissolves in water to decrease the surface tension of water. helpful in the Lungs |
6 carbon sugars monosaccharides (hexose) | Glucose, Fructose, Galactose |
5 carbon sugar monosaccharides (pentose) | Ribose and Deoxyribose |
6 carbon sugars disaccharides | Sucrose, Lactose . Maltose |
Another name for disaccharides | Dimers, |
Composion of Dimers | Sucrose.Lactose and Maltose are composed of a Glucose monosaccharide bonded to another hexose monosacchride |
Three or more monosacchrides are | polysacchrides |
When glucose is formed into a polysacchride for the purpose of storage in the liver or muscle tissue , this structure is known as | Glycogen |
The term used for the process of forming glycogen | Glycogenesis |
The term used for the process of breaking down glycogen | Glycogenelysis |
The term use for the liver producing Glucose from Non Carbohydrates like fats and proteins | Glyconeogenesis |
CH20 | Carbohydrate : hexose has 6 and pentose has 5 |
Nitrogenous bases for RNA | UGAC : Uracil, Guanine, Adenine, Cytosine |
Nitrogenous bases for DNA | TGAC : Thymine, Guanine , Adenine, Cytosine |
Chemical formula of DNA | Phosphate group, Deoxyribose sugar and one of its Nitrogenous bases, ( Thymine,Guanine,Adenine or Cytosine) |
What is the job of the Nucleic Acid | Storage and Expression of genetic materials |
Chemical formula of RNA | Phosphate group, Ribose sugar and one of its Nitrogenous bases (Uracil,Guanine,Adenine, or Cytosine) |
What are the monomers of Proteins | Amino Acids |
The 4 Lipids : PETS | Phospholipids, Eicosanoids, Triglycerides and Steroids , and are water insoluble |
Chemical formula of Adenosine Triphosphate (ATP) | Triphosphate group, Ribose sugar and the Nitrogenous base Adenine |
Chemical formula of an Amino Acid | Amine group, a single Carbon attached to a Hydrogen , Carboxyl group and 1 of the 20 R group |
Two characteristics that define an Amino Acid | R group and being polar, non polar, charged or special function |
Amino Acids Polar R groups characteristics are | Contain other elements added to the Hydrogen and carbons in their group, are Hydrophilic |
Amino Acids Non Polar groups characteristics are | Contains either Hydrogen or Hydrocarbons in their group, and are Hydrophobic and bond by Hydrophobic interactions with other non polar amino acids |
Amino Acids Charged groups characteristics are | Have either a negative or a positive charge, and are Hydrophilic |
DNA complimentary Nitrogenous bases | T to A ; Thymine to Adenine and C to G ; Cytosine to Guanine |
Isomers are | Having the same chemical formula but a different chemical structure |
Isotopes are | Atoms having the same number of Protons and Electrons but a different amount of Neutrons |
What causes isotopes to be unstable | Having an excess of Neutrons |
Measure of Particles in a solution | Osmoles; Osmolality is in kilograms of solution and Osmolarity is in Liters of solution. This is relevant to water movement by Osmosis |
HCO3- | Bicarbonate |
Acids do what with Protons (H+) | Donate |
Bases Receive what from Acids | Protons (H+) |
Hydrophobic interactions occur by what type of charge | dipole to dipole. a temporary unequal distribution of electrons |
Cohesion is | The attraction between water molecules |
Adhesion is | The attraction of water to substances other than water |
Surface tension is | The inward pulling of the water molecules at the surface |
Adding H+ to a neutral solution makes it | More Acidic |
Buffers help prevent changes by doing what | Releasing and Absorbing Hydrogen ions (H+) |
The 4 major classes of Organic Biological Macromolecules | Lipids, Carbohydrates, Nucleic Acids , and Proteins |
A diverse Carbon skeleton with a Functional Group attached is | A Biological Macromolecule |
How are the biological macromolecules formed and digested | By Dehydration Synthesis and Hydrolysis |
Out of the biological macromolecules, which one can not form a polymer | Lipids |
Triglycerides are composed of what | A Glycerol and three fatty acids, Glycerol , 3 fatty acids |
Phospholipids are composed of what | A Glycerol and two fatty acids, a Glycerol , 2 fatty acids , and a phosphate functional group , and some organic groups attached |
