Adhesion to the Xylem, and cohesion Condensation Reaction (Dehydration synthesis) Monosaccharide Anything ionic or polar. (Nonpolar molecules do not dissolve in water.) A reaction that gives off (generates) energy. Competitive Hydrogen, Ionic, Covalent Because hydrogen bonds hold water molecules loosely together. ADP Independent-what you are changing in the experiment; dependent-what you are measuring Proteins Cellulose Serves as a baseline for comparison cohesion The chemistry of carbon containing molecules. A protein, or a polymer of many amino acids. A peptide bond. They lower activation energy, and thus speed metabolic reactions. Hydrolysis reaction Nucleotide Between phosphate groups. Enzyme inhibition where a molecule binds to a site other than the active site. It “helps” the enzyme by delivering the substrate to it. Measure substrates, measure products Carbon, hydrogen, oxygen Cohesion (the result of hydrogen bonds) Because charge is unevenly distributed between hydrogen and oxygen. It is increasing. Physical location on an enzyme where a substrates bind. Temperature, pH, competitive inhibition, allosteric inhibition (may name any two) Water-loving. Means it will dissolve in water. A very large molecule made up of thousands of monomers. simple sequence of amino acids. Dependent variable with appropriate units Secondary structure Ionic-physical transfer of electrons between elements; Covalent-sharing of electrons between elements; Hydrogenbond of attraction between polar molecules There is no net change in the amount of products and reactants. Hydrogen & ionic Potential, kinetic When ATP hydrolyzes, the release of energy drives endergonic reactions Cellulose will not fit into the active site of the enzyme while starch will Polar covalent bonds Positive Hydrogen, Negative oxygen Acids 0-6.9, Neutral 7, Bases 7.1-14 ends in “ase” What the scientist manipulates or changes the study of life. Nucleic Acids Proteins Amino Acid
