FINAL
Solutions 100Solutions 100
The random movement of molecules (liquid or gas) until evenly
distributed
Diffusion
Solutions 200Solutions 200
In the Egg-speriment, what was the hypertonic environment?
Sugar/Corn Syrup
Solutions 300Solutions 300
The part of a solution that is usually present in greater quantity; it is what
dissolves the other substance in solution.
solvent
Solutions 400Solutions 400
Explain what will happen to this cell, given solute concentrations
Cell will swell
Solutions 500Solutions 500
Draw a cell in a hypotonic environment and show the osmotic
movement. Label solute and solvent.
[water moves into cell]
Cell Functions 100Cell Functions 100
This structure helps the cell create protein molecules. It is an organelle, but
it is not bound by a membrane.
Ribosome
Cell Functions 200Cell Functions 200
A cell missing this organelle might have difficulty sending molecules out of the
cell and therefore not be able to communicate with nearby cells.
Golgi Bodies/Apparatus
Cell Functions 300Cell Functions 300
A cell with many of these organelles would be present in muscles due to their higher energy requirements.
Mitochondria
Cell Functions 500Cell Functions 500
There are 2 types of this cell organelle, the difference being the
attachment (or lack) of ribosomes on the surface.
Endoplasmic Reticulum
Movement 100Movement 100
Molecules like CO2 and O2 gas move through cell membranes using this form of transport.
Simple Diffusion (or diffusion - ok)
Movement 200Movement 200
Embedded membrane proteins enable cells to do this type of diffusion.
Facilitated Transport/Diffusion
Movement 300Movement 300
Considering active transport and facilitated transport, give one
similarity and one difference.Similarity: requires the use of a membrane protein
Differences: Molecules move against concentration gradient vs. moving down gradient OR the use of energy (Active – requires energy. Facilitated – does not require energy).
Movement 400Movement 400
This molecule, produced in the mitochondria, is required in order
for Active Transport to occur.
ATP
Movement 500Movement 500
List 3 molecules or atoms that would have difficulty diffusing through the cell
membrane without facilitation.
(any charged ions, glucose, starch)
Cell Membrane 100Cell Membrane 100
The phospholipid “head” has this property and is what determines its
behavior and orientation.
hydrophilic
DAILY DOUBLE - Cell MembraneDAILY DOUBLE - Cell Membrane
List 3 synonyms of “cell membrane”
Plasma membrane, phospholipid bilayer, lipid bilayer, fluid mosaic
model
Cell Membrane 400Cell Membrane 400
Fluid mosaic model is an appropriate name for the cell membrane because?
Proteins, carbs, and other lipids are embedded throughout the membrane, like a mosaic. Also, they are not stationary.
Cell Membrane 500Cell Membrane 500
Aside from transport of molecules, what are other functions of
membrane proteins?(1)Support by attaching to the cytoskeleton and ECM, (2)cell-cell recognition, (3)enzymes, (4)receiving information/communication.
