Osmosis + Tonicity
Osmosis is a form of what type of transport
Passive transport/Simple diffusion
THIS ORGANELLE: Supports, protects, controls movement of materials in/out of cell, maintains homeostasis
Cell Membrane
Active transport requires _____.
ATP (cellular energy)
This protein simply allows for the passive (energy-less) movement of materials.
Channel proteins
Controls cell activities; contains the hereditary material of the cell
Nucleus
Substance in which a solute is dissolved
Solvent
The cell membrane is made of a bilayer of this macromolecule:
Phospholipids
What type of endocytosis involves liquids and nutrients?
Pinocytosis
These proteins are able to identify substances and invaders.
Cell recognition proteins
Carries materials through the cell and aids in making proteins
Endoplasmic Reticulum
Cell is placed in a hypertonic solution. Water will travel ________ and make the cell _________
Outside; Shrink/shrivel
The portion of the cell membrane that does not like water (...maybe even fears it!)
Hydrophobic fatty acid tails of phospholipids
What type of endocytosis involves large molecules like food, debris, and invaders?
Phagocytosis
This type of protein acts to catalyze reactions.
Enzymatic
Organelle that makes ribosomes:
Nucleolus
Concentration is lower outside of the cell than on the inside
Hypotonic solution
The portion of the cell membrane that is oriented towards water (...maybe even loves it!)
Hydrophilic phosphate heads of phospholipids
Active transport moves molecules ________ the concentration gradient.
Up OR against
These proteins physically transport a great variety of substances either passively or actively.
Carrier proteins
This organelle sorts and packages proteins and ships them off to their final destinations.
Golgi apparatus
If a cell is placed in a hypotonic solution, in which direction will water flow?
Into the cell (remember: water always flows from HYPO --> HYPER)
The cell membrane of the red blood cell will allow water, oxygen, and carbon dioxide to pass through. Because other substances are blocked from entering, this membrane is called __________.
Semi-permeable/selectively permeable
What type of endocytosis involves specific molecules sensed by proteins that trigger uptake?
Receptor-mediated endocytosis
These proteins are shaped specifically for particular molecules to bind to them.
Receptor proteins
This organelle synthesizes proteins:
Ribosomes
