correct answers
Pinocytosis |- |Answer |Cell |drinking

Exocytosis |- |Answer |release |of |substances |outside |a |cell |by |the |fusion |of |a |vesicle |with
|the |membrane.
Endocytosis |- |Answer |process |by |which |a |cell |takes |material |into |the |cell |by |infolding
|of |the |cell |membrane
osmosis |- |Answer |Low |to |High, |Diffusion |of |water |through |a |selectively |permeable
|membrane
Diffusion |- |Answer |Movement |of |molecules |from |an |area |of |higher |concentration |to |an
|area |of |lower |concentration.
tonicity |- |Answer |the |ability |of |a |surrounding |solution |to |cause |a |cell |to |gain |or |lose
|water
isotonic |solution |- |Answer |when |the |concentration |of |two |solutions |is |the |same
|(moving |in |and |out |equally)
hypertonic |solution |- |Answer |A |solution |in |which |the |concentration |of |solutes |is |greater
|outside |then |inside |the |cell |that |resides |in |the |solution
hypotonic |solution |- |Answer |Solute |concentration |is |less |than |the |inside |the |cell; |cell
|gains |water
oncotic |pressure |- |Answer |pulls |fluid |into |the |capillaries |and/or |prevents |fluid |from
|leaving.
hydrostatic |pressure |- |Answer |increases |filtration |by |pushing |fluid |and |solute |OUT |of
|the |capillaries
crenation |- |Answer |This |happens |when |a |cell |shrinks |and |shrivels; |can |result |in |cell
|death |if |severe.
hemolysis |- |Answer |destruction/split |of |red |blood |cells
active |transport |- |Answer |the |movement |of |ions |or |molecules |across |a |cell |membrane
|into |a |region |of |higher |concentration, |assisted |by |enzymes |and |requiring |energy.
passive(facilitated) |transport |- |Answer |the |movement |of |substances |across |a |cell
|membrane |without |the |use |of |energy |by |the |cell
, Co-transport |- |Answer |TWO |substances |are |transported |together |by |one |protein |no
|ATPase |activity
Countertransport |- |Answer |One |substance |is |being |transported |into |the |cell |membrane
|and |the |other |is |getting |transported |in |the |opposite |direction.
What |are |some |factors |that |affect |diffusion? |- |Answer |• |Temperature
• |Solvent |Density |
• |Distance |traveled
Simple |Diffusion |- |Answer |high |to |low |concentration |easy |to |flow |through |cell
|membrane; |Oxygen |is |an |example

the |structure |of |the |mitochondrion |- |Answer |outer |membrane, |inter |membrane |space,
|inner |membrane, |cristae |(folds |in |im), |matrix
phosphorylation |- |Answer |The |metabolic |process |of |introducing |a |phosphate |group
|into |an |organic |molecule.
Hydrolysis |- |Answer |how |the |body |breaks |the |bonds |between |the |last |two |phosphates
|in |ATP, |which |is |what |gives |us |energy
ATP |synth(make)-ase |(Enzyme) |does |what? |- |Answer |Makes |ATP
ATP-ase |(Enzyme) |- |Answer |break |down |of |ATP
Metabolism |- |Answer |"Work" |the |chemical |processes |that |occur |within |a |living
|organism |in |order |to |maintain |life.
Glucose |- |Answer |"Bodies |Gold" |A |simple |sugar |that |is |an |important |source |of |energy.
ATP |- |Answer |(adenosine |triphosphate) |main |energy |source |that |cells |use |for |most |of
|their |work
ADP |- |Answer |(Adenosine |Diphosphate) |The |compound |that |remains |when |a
|phosphate |group |is |removed |from |ATP, |releasing |energy
AMP |- |Answer |Adenosine |monophosphate, |ATP |minus |2 |phosphate |groups
