Cells Flashcards
Function of nucleus
Stores DNA
Function of ribosomes
Makes protein
Function of Soft ER
Makes lipids , detoxifies cell
Function of lysosome
Contains hydrolytic enzymes to break down macromolecules ( proteins, lipids , carbohydrates, nucleotides)
Function rough ER
Proteins travel through golgi
Function of golgi
Receives lipids / proteins , modifies ( add sugar ) and ships them out of the cell
Compare / contrast Simple and facilitated diffusion
No ATP needed move from high to low concentration of solute butch nice substances across the membrane
What way will water move
Water goes in water always travels from high to low concentration solute
Osmosis
Movement of water, moves across membrane , moves from high concentration to low concentration of water
Isotonic solution
The concentration of solute is the same inside and outfitter the cell
Hypertonic
The concentration of the solution is higher outside the cell
Hypotonic
The concentration of solution is lower outside cell : water enters
Exocytosis
Using ATP to allow large substances to leave the cell
Endocytosis
Using ATP to allow substances to enter cell
Pinocytosis
Small molecules ( lots ) or liquids-see above , but smaller and without lysomes
