Answers
What is a Cell? - ANSW-Basic unit of life
How are new cells created? - ANSW-New cells arise only from pre existing cells. ( You can't make
something from nothing)
What are the two major components of Eukaryotic cells? - ANSW-1. Plasma Membrane
2. Cytoplasm - semi-fluid substance within the cell.
What does the Plasma Membrane of a cell do? - ANSW-1. separates the cell's contents from its
surroundings.
2. The PM dictates what can move in and out of the cell.
Where are Glycoproteins and Glycolipids found? - ANSW-They are found on the outside surface of the
plasma membrane.
What do Glycoproteins and Glycolipids do? - ANSW-They act as receptors for different molecules and
they also help your body identify cells.
Does the Plasma Membrane have selective permeability? - ANSW-Yes
What is selective permeability? - ANSW-It helps decide what goes in and out of the cell.
What is an Aquaporin? - ANSW-An aquaporin is a channel that lets water come in and out of the cell.
What is Diffusion? - ANSW-The movement of particles from an area of high concentration to an area of
low concentration.
What is an example of diffusion? - ANSW-Dropping food coloring into water.
What is osmosis? - ANSW-The movement of water. (Water can transfer back and forth between the
membrane. A selective permeability is always present in osmosis)
What is Tonicity? - ANSW-A term that describes the water characteristics of a solution.
isotonic solution - ANSW-A solution in which the concentration of solutes is essentially equal to that of
the water cell which resides in the solution
hypotonic solution - ANSW-The solution has more water outside so water will go into the cell.
Hypertonic Solution - ANSW-there is less water outside than inside therefore, water will come out of the
cell.
facilitated diffusion (passive transport) - ANSW-movement of molecules across a membrane via
transport proteins without energy from ATP hydrolysis
protein carriers - ANSW-bind to and transport substances across the membrane
active transport - ANSW-Moving things from low to high concentration. Uses energy.
Bulk Transport: Endocytosis - ANSW-movement of substances into the cell
bulk transport: exocytosis - ANSW-movement of substances out of the cell
What are the two types of endocytosis? - ANSW-phagocytosis and pinocytosis
What is phagocytosis? - ANSW-Taking something inside the cell for destruction
, What is pinocytosis? - ANSW-Bringing in some fluid from outside the cell. (Cell drinking)
receptor-mediated endocytosis - ANSW-A molecule on the surface of the plasma membrane will bind to
whatever they are bringing into the cell and then the molecules engulf it into the cell.
What is cytosol? - ANSW-Fluid portion of cytoplasm
What is the Nucleus of the cell? - ANSW-control center
What is the endoplasmic reticulum? - ANSW-site of cellular protein synthesis
What is the mitochondria? - ANSW-Powerhouse of the cell
What is the golgi apparatus? - ANSW-Another membrane of the cell which is used for transportation
throughout the cell
What are ribosomes? - ANSW-site of protein synthesis
What is the cytoskeleton? - ANSW-skeleton of the cell
What is in the Nucleus? - ANSW-1. All genetic information
2. Start of Protein synthesis
3. Control Center
What is the rough and smooth endoplasmic reticulum? - ANSW-Rough- holds ribosomes, smooth, does
not have ribosomes. This is the internal delivery system of the cell
What do Lysosomes do? - ANSW-They have digestive enzymes and they are used to break things down
so that they can spit them out as waste. When they don't work properly, they can malfunction and begin
to break down the cell.
What does the mitochondria do? - ANSW-It provides ATP, which is ENERGY. Athletes have more
mitochondria in their cells. Mitochondria has its own DNA, and therefore, it can reproduce on its own.
What are the 3 types of cellular respiration? - ANSW-1. Glycolysis
2. Krebs Cycle
3. Electron Transport Train
Glycolysis (cellular respiration) - ANSW-It can occur in any cell in the Cytosol. It does not require any
oxygen but they downside is, it does not produce a lot of ATP. (only makes 2 molecules)
Krebs cycle (cellular respiration) - ANSW-Only Occurs in the Mitochondria - larger amounts of ATP
produced
Electron Transport Chain (cellular respiration) - ANSW-Where the bulk of your ATP comes from. This
process requires a lot of oxygen.
What are ribosomes? - ANSW-They make your proteins
Free Ribosomes - ANSW-Proteins that are for use inside of the cell
fixed ribosomes - ANSW-Proteins they make are moved into the outside of the cell
Cytoskeleton - ANSW-The skeletal structure of the cell and it assists with the movement of the cell.
a) microtubules,b) intermediate filaments, c)microfilaments - ANSW-a. the largest-They help maintain
shape and move organelles, they help make a cell mobile.
b. medium - structural variable in action
c. the smallest - motion within the cell
Adhesion Junction - ANSW-Where the cytoskeletons from both cells bind the cells together
