Terms | Definitions |
|---|---|
 cellular respiration occurs in | the mitochondria of cells |
| cellular respiration process | sugar (glucose) is converted to ATP glucose+O2+ADP = ATP+CO2+H2O (ADP is "recharged" into ATP) |
| ATP vs ADP | ATP: triple P ADP: double P |
| 3 types of food molecules | Protein, Fat, Carbohydrates |
| Protein | chains of amino acids; only amino acids are small enough to pass through the digestive tract and into the body |
| Fat | glycerol bonded to 3 fatty acids, high energy, must be broken down into the glycerol before absorption |
| Carbohydrates | individual/chains of simple sugar units |
| starch | simple sugars joined together, found in plants |
| glycogen | blood sugar |
| cellulose | cannot be broken down in the human body |
| digestive system | mouth, pharynx (throat), esophagus, stomach, small/large intestine, rectum |
| most of digestion occurs in | the small intestine |
| when do food molecules enter the circulatory system? | after passing through the liver |
| -ose | sugar |
| -ase | enzyme |
| anorexia | self-starvation |
| bulimia | binge eating, then ridding the body of food |
| why eating disorders are deadly | no energy for cellular respiration, proteins cannot be produced, heart shrinks |
| why does the body have so many parts and accessory glands? | because different food molecules require different breakdown steps |
| zyklon B | blocks cellular respiration and denies brain cells ATP |
