ASU BIO 181 Exam 1 Question and
Answer | Grade A+ Guaranteed
• Actin Filaments are present in: -✓✓The cell's cortex
• Microtubules are present in: -✓✓The cell's interior
• Cytokinesis in plant and animal cells takes two forms: -✓✓Animal: Contractile Ring
Formation
Plant: Phragmoplast Formation
• An important checkpoint regulator is at the Gap 2/M-phase transition. Here, Cyclin B
and cdkl1 activate and form MPF which becomes a _____ _____ and causes DNA to
condense into _____. -✓✓Histone Kinase
Chromosomes
• The _____ begins to be destroyed at the Metaphase of the cell cycle causing the
chromosomes to begin to _____. -✓✓Cyclin B1
Decondense
• The activation of both MPF and MAPK result in _____ _____ of the cytoplasm during
M-phase. -✓✓Settling down
• MAPK has two different functions depending on where this Kinase acts in the _____
_____. If the Kinase becomes active during interphase, the cell is triggered to progress
through the _____ _____. -✓✓Cell cycle
Cell cycle
• Two types of second messengers discussed in lecture can exist downstream of a
plasma membrane receptor. These are _____ and _____. -✓✓Cyclic AMP
MAP Kinase
• There are two basic forms of cytoplasmic signaling (i.e signal transduction). One uses
_____ and the other uses _____. -✓✓Protein Kinases
Calcium Signal
• What is the difference between a single-pass transmembrane protein and a 7-pass
transmembrane protein? -✓✓A single pass TMP is a singular protein that passes once
through the bilayer. A 7-pass protein passes through the bilayer 7 times, creating a
channel for ions to pass through. A single pass TMP cannot create an ion channel.
• Is a cancer cell anchorage independent and immortal, or is it anchorage dependent
and mortal? Do they exhibit contact inhibition? -✓✓They are anchorage independent
, and immortal, and they do not exhibit contact inhibition, because they continue to grow
despite their surroundings.
• If something is soluble in water, a hydration forms around it and it is termed: -
✓✓Hydrophilic.
• What limits the paramecium from acquiring more complex functions? -✓✓The
paramecium cannot fit any more biomachinery into its space.
• What limits an individual cell from becoming more complex? -✓✓Division of labor.
• T/F: In your own multicellular body, different cells have a division of labor between
them: -✓✓True.
• T/F: A normal cell is anchorage-dependent for growth and mortal: -✓✓True.
• Comparing a single-celled Eukaryotic organism with a multi-cellular organism such as
yourself, what is the major difference: -✓✓Division of labor.
• T/F: In your own multicellular body, cells with different functions have different DNA: -
✓✓False.
• A single celled Eukaryotic organism: -✓✓Has a limited number of biomolecular
machines
Must find food, shelter, a mate, and reproduce
Must escape from predators
• The paramecium discussed in class has contained an organelle called the contractile
vacuole. This is the presumed precursor of the: -✓✓Kidney.
• T/F: A cell that is anchorage-dependent for growth will also exhibit contact inhibition: -
✓✓True.
• In order to examine cells that are smaller than can be detected by the human eye,
what needs to be used? -✓✓Technology.
• Compared to bacteria, which of the cell types are not responsible for finding food? -
✓✓Lymphocyte
Macrophage
Fibroblast
• In cell biology, what can limit the progress of science? -✓✓Technology.
