organic compound containing carbon, hydrogen, and oxygen in a ratio of one oxygen and two hydrogen atoms from each carbon atom. |
|
|
enzyme |
protein that speeds up a biological reaction by lowering the activation energy needed to start the reaction. |
|
|
what provides the energy for all loving processes? |
chemical bonds |
|
|
macromolecule |
large molecule formed by joining smaller organic molecules together |
|
|
polysaccharide |
a carbohydrate, as starch, inulin, or cellulose, containing more than three monosaccharide units per molecule, the units being attached to each other in the manner of actels, and therefore capabale of hydrolysis by acids or enzymes to monosaccharides. |

protein |
|
|
what is the upward curve on a graph thingy |
activation energy |

|
explain why chemical equations must be balanced |
chemical reactions require balance of mass. Therefore, the number of astoms of each element on the reactant side must be equal the number of atoms of the same element on the product side |
