|
molecule
|
a group of atoms held together by the energy of chemical bonds
|
|
molecular compounds

|
must contain hydrogen and carbon, living
|
|
carbohydrates
|
organic, supplies enegry for cell process

|
diffusion
|
when atoms from a crowed area move to a less crowded place.
high to low |
|
facilitated diffusion
|
the process when objects too big to fit into the membrane get helped by the transport protiens
|
|
active transport
|
when energy is used topass materials through the membrane
|
|
vesicle
|
transport/storage structures in the cytoplasm
|
|
exotytosis
|
when the vescils contents are released
|
|
endocytosis
|
when the vesicls take contents into the membrane

|
enzymes
|
work like can openers
reusable can cause molecules to join |

photosynthesis
|
when plants/producers use sunlight to make food
|
|
resperation
|
when food molecules are being broken down into simpliar substances
|
|
fermentation
|
when cells dont have engough oxygen for resperastion, they release some of the stored enegry
