section 1
| Question | Answer |
|---|---|
| exergonic reactions | The processes that releases or gives off energy |
| endergonic reactions | Reactions that require or take in energy |
| Thermodynamics | the field of science dealing with the study of energy |
| Oxidation | the loss of an electron |
| Reduction | the gain of an electron |
| Anabolism | the series of chemical reactions that build organic molecules |
| Catabolism | the series of chemical reactions that break down larger molecules |
| enzyme | brings together reactant molecules and promotes a chemical change |
| catalyst | any chemical that affects the rate of a chemical reaction but is not changed by the reaction |
| Carbonic anhydrase | causes certain chemicals to react 107 times faster than they would if the enzyme were not present |
| enzyme peptidase | breaks bonds that link amino acids in proteins |
| Tay-Sachs disease | an inherited condition caused by a defective enzyme called hexosaminidase |
| Information stored in DNA | determines a protein’s amino acid sequence |
| amino acid sequence | determines how the protein chain folds to create a three-dimensional shape |
| enzymatic pathway | a sequence of reactions that depend on one another that modify molecules, through a series of steps, into different products |
| short lifetime of intermediate products | ensures that the reactions will proceed in the "preferred" direction. |
| Increases in temperature will? | speed up enzyme-mediated reactions, but only to a point |
| when heated too much an enzyme? | enzyme loses its shape and thus its function, but will regain function when temperature returns normal |
| Thermolabile enzymes | enzymes that function differently when warmed,but work better at lower tempatures |
| Chymotrypsin | an enzyme in the stomach that must be activated by the low pH (high acidity) of the stomach. |
| allosteric sites | here molecules other than the substrate can bind. |
| Nerve gas | permanently blocks pathways used to transmit nerve messages and results in death. |
| Autotrophs | living things that use sunlight to make organic compounds. Like plants |
| heterotroph | Humans and other animals that get energy from food instead of directly from sunlight |
| adenosine triphosphate (ATP) | transfers energy released from chemical bonds of molecules like glucose to energy-absorbing reactions within the cell. |
| Nucleotides are composed of? | sugar, a nitrogen-containing base, and a phosphate group |
| ATP is composed of? | a sugar, a base, and three phosphate groups that are linked together |
