BIM & CR
| Term | Definition |
|---|---|
| enzyme | biological catalyst |
| denaturing | causes enzyme to lose shape and functionality |
| causes of denaturation | heat, ph, salinity |
| critical to digestion | amylase & lactose |
| produced throughout GI tract | amylase & lactose |
| most abundan water | most abundant molecule |
| mineral | least abundant molecule |
| catalyst | speeds up chemical reactions |
| enzyme shape determines substrate specificity | determined by interaction of R groups |
| lactose is the substrate to | lactase |
| lactase in small intestine breaks down lactose which then breaks down | galactose and glucose which is then absorbed into the bloodstream |
| goal of cellular respiration | to break down glucose to carbon dioxide in order to produce glucose |
| inputs of cellular respiration | glucose & oxygen |
| outputs of cellular respiration | carbon dioxide, water, atp |
| four main bims | carbohydrates, lipids, proteins, nucleic acids |
| functions of water in living cells | solvent, temp moderation, medium for chemical reactions, transportation, communication |
| minerals are needed in trade amounts because | it’s essential to functioning |
| how many trace elements are needed by organisms? | 20 |
| types of trace elements in living cells | iodine, copper, magnesium, potassium, zinc, iron, manganese |
| polymers | chains of monomers |
| macromolecules | large molecules made up of monomers and polymers |
| lactose | sugar found in milk & milk products; lactose intolerance happens when small intestine doesn’t make enough lactase |
| lactase | breaks down the lactose so body can absorb |
| monomer | chemical subunit of polymers |
| all BIMS except _____ have nutritional value | nucleic acid |
| what does hydrolysis do | breaks down molecules in the GI tract for use in cellular respiration |
| what are our cell’s proffered fuel source? | simple sugars |
| what % of carbs should be put in our daily calories? | 58% |
| carbohydrates | simple or complex |
| types of carbs | monosaccharides, disaccharides, polysaccharides |
| proteins | complex molecules made up of amino acids |
| essential amino acids | obtained from our food |
| non essential amino acids | our cells make them from our EAAS |
| lipids are ____ in water | insoluble |
| functions of fats | thermoregulation, protection, energy |
| carbs break down ____ due to ____ in our saliva | easily, amylase |
| fats take a ____ time to break down | longer |
| % of fat that should be in our daily calories | 30% |
| the plasma membrane is | selectively permeable |
| selectively permeable | controls what moves in/out |
| passive transport | doesn’t require energy because it relies on concentration gradient |
| osmosis | movement of water molecules across a membrane |
| diffusion | movement of solute molecules across a membrane |
| facilitated diffusion | movement of large molecules across a membrane using transport proteins |
| active transport | requires energy (ATP) |
| small cell size = | large surface area to volume ratio |
| the smaller the cell | the more rapid diffusion /transport is happening across the membrane |
| nutrients are used for ____ during cellular respiration | oxidation |
| first step of cellular respiration | glycolysis |
| second step of cellular respiration | pyruvate oxidation |
| third step of cellular respiration | citric acid cycle/ Krebs cycle |
| fourth step of cellular respiration | electron transport chain |
