700
These are the functions (name 2) of the smooth E.R.
Continue
What is lipid production, carbohydrate metabolism, drug detoxification and
calcium release
800
Vesicles that bud from the E.R. join the cis face of this organelle; this
organelle helps to process and package them where the vesicles are then “pinched” off of the trans face.
What is Golgi apparatus
Continue
900
In eukaryotes, this organelle makes rRNA and adds it to proteins to make ribosomal subunits, which are passed
out of the nucleus to aid in protein formation.
What is NucleolusContinue
1000
Prokaryotes do not have nuclei, but they have “this region” where DNA is
concentrated
What is the nucleoid
Continue
100
The cellular structure that is involved in producing ATP during aerobic
respiration
What is Mitochondria
Continue
200
This organelle contains enzymes that break down fatty acids for energy or
detoxify alcohol and poisons; converts H2O2 to water
What is a peroxisome
Continue
300
This is an example of a type of plastid (and this plastid’s function)
What is (e.g.) a chloroplast (contains chlorophyll to help function in
photosynthesis Continue
400
All cells have “these” 4 things in common
What is a)plasma membrane, b)ribosomes, c)genetic material, d) cytosol, etc.
Continue
500
Within the mitochondria’s phospholipid bilayer is a mitochondrial
matrix (where respiratory enzymes help in respiration). This matrix is surrounded by these large surface area folds on the inner membrane
What are CristaeContinue
600
Mitochondria and chloroplasts contain a small amount of this nucleic acid
(that directs sythesis of some of their proteins)
What is DNA
Continue
700
This organelle is not part of the endomembrane system and can grow
larger and increase in number by splitting in two when they reach a
certain size
What is a Peroxisome
Continue
800
Within a chloroplast’s double membrane is
a)“this fluid”, b)“these flattened sacs” and c) “many flattened sacs
stacked together”
What is stroma, thylakoid and grana
Continue
900
This endomembrane organelle can be confused with H2O2 decomposers, but this organelle fuses with and digests food vacuoles and aids in autophagy
What is Lysosome
Continue
1000
Roots and tubers store this colorless plastid (that stores starch)
What are Amyloplasts
Continue
200
This is a lab tool used in the cell fractionation process where denser
substances are separated from smaller, less dense substances in a
“fast spinning” process
What is a centrifuge
Continue
300
An endocytosis process where a cell takes in fluid-like material (in an invagination process with the cell
membrane)
What is pinocytosis
Continue
500
What organelle is expected to be found in abundance in the arm
muscles of an Olympic weight lifter
What are mitochondria
Continue
600
These pump excess water out of the cell, thereby maintaining the
appropriate concentration of salts and other molecules.
What is a contractile vacuole
Continue
700
These are two sites of protein synthesis within a cell
What are cytoplasm, mitochondria, and/or E.R.
Continue
800
Chloroplasts and mitochondria contain prokaryote-like ribosomes, so they are
thought to have evolved from “this Kingdom”.
What is Monera (the bacteria)
Continue
900
This is the primary difference when comparing mitochondrial and
chloroplast membranes
Mitochodria is a bilayer…chloroplast is a “trilayer” (2 outer membranes and thylakoid “membranous system”).
Continue
1000
Cilia and flagella move due to their interaction of the cytoskeleton with
these types of proteins
What are Motor Proteins
Continue
100
This is the name of the currently accepted model describing cellular
membranes
What is the Fluid Mosaic Model
Continue
200
In 2003, this award was rewarded to Agre and MacKinnon who worked on ion and water transport across the
plasma membrane
What is the Nobel Prize in Chemistry
Continue
300
Getting hungry yet? This membrane model inferred that all membranes
were treated equal and that hydrophilic proteins coated both sides
of the membrane.
What is the DAVSON-DANIELLI sandwich model
Continue
400
This “steroid” is a temperature buffer for membranes, as it makes
membranes less fluid by restraining movement of phospholipids but it also
lowers the membrane solidification temperature.
What is cholesterolContinue
500
This “very cool” word describes molecules that have both hydrophilic and hydrophobic regions (and thus
lend themselves to make great membranes!)
What is “amphipathic”Continue
600
In order for membranes to work properly, they must have the
approximate consistency of “this” (give a food example)
What is salad oil
Continue
700
Glycoproteins and glycolipids are short-branched segments of “these” that are covalently bonded to lipids
and proteins and play a functional part in the membrane.
What are carbohydrates
Continue

This general class of proteins spans the membrane bilayer where the
hydrophobic, nonpolar amino acids are near the hydrophobic tails…and the hydrophilic portions are found on the outside and inside of the membrane
What are integral proteins

the available space
What is diffusion
Continue
200
Hydrophilic substances that need to get into and out of the cell do not do well going through the hydrophobic
part of the membrane. So they might pass through these hydrophilic
channels
