| A | B |
|---|
| eukaryotic cells | have a nucleus and membrane bound organelles |
| prokaryotic cells | do not have a nucleus or membrane bound organelles |
| endothermic | absorb energy |
| exothermic | release energy |
| semi-permeable | is a membrane that only allow certain substance to easily pass through |
| active transport | moving a substance across the membrane using energy |
| passive transport | moving a substance across the membrane not using energy |
| diffusion | movement of a substance from high concentration to low concentration |
| osmosis | diffusion of water |
| what is an enzyme | proteins that speed u p chemical reactions |
| how do ph and temperatures effect enzymes functioning | ph when the ph is higher or lower than optimal, the enzyme doesn't work |
| protein a.k.a.(amino acids) | make up hair, nails, teeth, neurotransmittors, antibodies enzymes |
| carbohydrates a.k.a. (saccharide) | provide energy |
| lipids a.k.a (fatty acids) | insulate organs, cushioning stor energy |
| nucleic acids a.k.a ( nucleotides) | DNA , RNA |
| Three types main types of chemical bonds | iornic, covalent, and hydrogen |
| iornic bonds | occurs betrween + and - charged atoms a.k.a(ions) electrons are shared unequally |
| covalent bonds | electrons are shared equally |
| hydrogen bonds | weak bonds between hydrogen and another element is a substance that can't be broken down |
| what does a cell use ATP for? | energy |
| What is the formula for photosynthesis? | CO2 + light + H2 O > C6 H 12 O6 +O 2 |
| reactants are on the right or left | left |
| products are always on the left or right | right |
| Characteristics of life are | cellularity, metabolism, homeostasis, herdity, and reproduction |
| hypothalamus | detects body temp |
| what happens when your body temp goes up | blood vessels dialate to release heat |
| what happens when your body temp drops | your blood vessels will constrict to conserve a.k.a.( keep) heat |
