Thel processl byl whichl cellsl absorbl moleculesl byl engulfingl them.
Q:l Exocytosis
Answer:
Thel processl byl whichl cellsl releasel substancesl storedl inl vesiclesl outsidel thel cell.
Q:l Restingl Membranel Potential
Answer:
Thel electricall chargel differencel acrossl thel plasmal membranel ofl al restingl cell,l typicallyl aroundl -70mV.
Q:l Simplel Diffusion 1 / 3
Answer:
Thel passivel movementl ofl moleculesl froml anl areal ofl higherl concentrationl tol anl areal ofl lowerl concentration.
Q:l Facilitatedl Diffusion
Answer:
Thel passivel transportl ofl moleculesl acrossl al celll membranel withl thel helpl ofl transportl proteins.
Q:l Osmosis
Answer:

Q:l Sodium-Potassiuml Pump
Answer: 2 / 3
Movesl 3l sodiuml ionsl outl &l 2l potassiuml ionsl intol cell,l creatingl al morel negativel chargel inl thel cell.l Musclel andl Nervousl systeml relyl onl it.
Q:l Depolarization
Answer:
Na+l channelsl openl andl Na+l entersl thel cell,l makingl itl morel positive.
Q:l Repolarization
Answer:
Na+l channelsl close,l K+l channelsl open,l andl K+l rushesl outl ofl thel cell.l Afterl depolarizationl &l repolarization,l thel sodium-potassiuml pumpl helpsl thel celll returnl tol RMP.
Q:l Organelles
Answer:
Tiny,l organizedl structuresl thatl performl functionsl withinl ourl cells.l Membranousl organellesl arel coveredl withl al lipidl membrane,l includingl thel Nucleus,l mitochondrion,l lysosomes,l peroxisomes,l Endoplasmicl reticuluml (smoothl &l rough),l Golgil complex.l Non- membranousl organellesl arel generallyl madel ofl proteinsl andl notl coveredl withl lipids.
Q:l Nucleolus
Answer:
Darkl regionl atl thel centerl ofl thel nucleusl madel ofl chromatinl (thread-likel strandsl ofl DNA).
Q:l Inclusionl Bodies
Answer:
