difference between words or phrases from chapter
| Question | Answer |
|---|---|
| kinetic energy and potential energy | kinetic:doing work. potential: stored. |
| exergonic reactions and endergonic reactions | exergonic: release energy. endergonic: consumes energy. |
| reactants and products | in a chem reaction, reactants are changed into products. |
| atp and adp | ADP: phosphorilated, producing ATP. ATP: gets hydrolyzed (a phosphate group is removed) and ADP is produced. |
| a reaction without an enzyme and a reaction with an enzyme | Enzymes lower the energy of activation for a reaction, so the reaction with an enzyme requires less energy to get it started than the reaction without the enzyme. |
| photosynthesis and cellular respiration | Photosynthesis: energy of sun is used to make glucose from carbon dioxide and water. Cellular Respiration: Oxygen and glucose combine, and the energy in the glucose is used to make ATP |
| first and second laws of thermodynamics | First law: energy can be transferred or transformed but not created or destroyed. Second law: energy changes are accompanied by an increase in disorder, or entropy. |
| mechanical, transport, and chemical work | Mechanical: movement of cell or body. Transport: moving substances through cell membranes. CHemical work: building molecules. |
