Question
Answer
macromolecules   show
🗑
Polymer   show
🗑
monomer   show
🗑
dehydration reaction   show
🗑
show protein that acts as a biological catalyst  
🗑
show a chemical reaction that breaks apart a larger molecule by adding a molecule of water  
🗑
Carbohydrates   show
🗑
show The simplest carbohydrate, serve as a monomer for disaccharides and polysaccharides. Also known as simple sugars, the molecular formulas of are generally some multiple of CH2O.  
🗑
show A double sugar, consisting of two monosaccharides joined by a glycosidic linkage through dehydration synthesis.  
🗑
show A covalent bond formed between two monosaccharides by a dehydration reaction.  
🗑
show A polymer of up to over a thousand monosaccharides, formed by dehydration reactions. There are two main types of polysaccharides: storage and structural polysaccharides.  
🗑
Starch   show
🗑
Glycogen   show
🗑
show A structural polysaccharide of cell walls, consisting of glucose monomers joined by b-1- 4 glycosidic linkages.  
🗑
Lipid   show
🗑
show Three-carbon alcohol with three hydroxyl groups; component of fats and oils.  
🗑
show A long carbon chain with an attached carboxyl group attached to the end and a hydrocarbon chain attached to the carboxyl group. It is this hydrocarbon chain which gives the fatty acid a hydrophobic nature.  
🗑
Ester linkage   show
🗑
show 3 fatty acids (chains of hydrocarbons) bonded to a glycerol, most fats are eaten and absorbed in this form, carbohydrate  
🗑
show fatty acid chains lacking double bonds; therefore, the chains pack tightly, are solid at room temp and bad fats, major source is animals  
🗑
show Fats that contain one or more double bonds between carbon atoms and have less than the maximum number of hydrogen atoms bonded to carbon  
🗑
show artificial fat made from the process of hydrogenation; believed to increase a person's risk for coronary artery disease  
🗑
Phospholipids   show
🗑
show A type of lipid characterized by a carbon skeleton consisting of four rings.  
🗑
show a steroid that forms an essential component of animal cell membranes and acts as a precursor molecule for the synthesis of other biologically important steroids, such as hormones.  
🗑
Proteins   show
🗑
enzymatic proteins   show
🗑
show Proteins that are important for holding cells and organisms together, such as the proteins that make up the cell membrane, muscles, tendons, and blood  
🗑
polypeptides   show
🗑
show organic molecules possessing both carboxyl and amino groups that are linked together to form large protein molecules  
🗑
peptide bond   show
🗑
show small spherical proteins with little to no water inside. They have hydrophobic amino acids in the inside and hydrophilic R groups on the outside.  
🗑
fibrous proteins   show
🗑
primary structure   show
🗑
secondary structure   show
🗑
show spiral shape created by polypeptide chains that inter twine around each other  
🗑
show One form of the secondary structure of proteins in which the polypeptide chain folds back and forth. Two regions of the chain lie parallel to each other and are held together by hydrogen bonds.  
🗑
show irregular contortions of a protein molecule due to interactions of side chains involved in hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridges  
🗑
show As a polypeptide folds into its functional conformation, amino acids with hydrophobic side chains usually end up in clusters at the core of the protein, out of contact with the water.  
🗑
show Strong covalent bonds formed when the sulfur of one cysteine monomer bonds to the sulfur of another cysteine monomer.  
🗑
quaternary structure   show
🗑
show a structural change in a protein that results in a loss of its biological properties  
🗑
show protein molecules that assist the proper folding of other proteins  
🗑
show a technique that depends on the diffraction of an X-ray beam by the individual atoms of a crystallized molecule to study the three-dimensional structure of the molecule.  
🗑
show sequence of DNA that codes for a protein and thus determines a trait  
🗑
show Polymers assembled from individual nucleotides; used to store and transmit hereditary, or genetic, information; the two kinds of nucleic acids are ribonucleic acid (RNA) and deoxyribonucleic acid (DNA)  
🗑
DNA   show
🗑
show ribonucleic acid; a nucleic acid that plays an important role in the production of proteins  
🗑
mRNA   show
🗑
show A polymer consisting of many nucleotide monomers.  
🗑
show monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base  
🗑
nucleosides   show
🗑
show nitrogenous bases that have a single ring of carbon and nitrogen atoms, such as cytosine and thymine  
🗑
purines   show
🗑
ribose   show
🗑
show five-carbon sugar that is a component of DNA nucleotides  
🗑
double helix   show
🗑
show The opposite arrangement of the sugar-phosphate backbones in a DNA double helix.  
🗑
show thymine  
🗑
Guanine   show
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
