Cell Communication and Cycle Review Game
Savanah Hipp
2.
How to Play
Up to 4 people can play at a time
One player will read the questions
The other three will stand around a stool with hands by sides
First person to hit middle of stool tries to answer question, if wrong, passed to next player
1 correct answer = 1 pt, most puts wins!
3.
What do cells use to communicate?
chemical signals
4.
What is a series of steps that converts a received signal to a specific cellular response?
signal transduction pathway
5.
What are direct cytosol passages that allow free flow of chemical signals from one cell to another?
cell junctions
6.
What is a process that uses cell membrane contact to communicate?
cell to cell recognition
7.
What carries chemical messages over short distances?
local regulators
8.
What carries chemical messages over long distances?
hormones
9.
What are the three steps of the signaling process?
reception, transduction, response
10.
What are two common second messengers?
cAMP & calcium ions
11.
Why are calcium ions an important second messenger?
the cell can regulate the concentration of
12.
What can pathways regulate about enzymes?
Synthesis & Activity
13.
How are signals amplified along the pathway?
with each step, more products are activated
14.
What is apoptosis?
programmed cell death
15.
What is observed when daughter cells are compared?
genetically identical
16.
What is all DNA in a cell called?
genome
17.
What holds sister chromatids together?
centomere
18.
What is mitosis the division of?
genetic material or DNA
19.
What is cytokinesis the division of?
Cytoplasm or cytosol
20.
What are the sub phases of interphase?
G1, S, G2
21.
What are the parts of the mitotic spindle?
centrosomes, microtubules, asters
22.
What are the phases of mitosis?
prophase, prometaphase, metaphase, anaphase, telophase; NOT cytokinesis
23.
What is the imaginary line where the chromosomes line up during mitosis called?
metaphase plate
24.
How does cytokinesis take place in animals? Plants?
cleavage; cell plate
25.
What is mitosis believed to be evolved from and what kind of organism does it take place in?
binary fission; bacteria or prokaryotes
26.
How is the cell cycle driven?
specific signaling molecules in cytoplasm
27.
What is the most important checkpoint and why?
G1 because if there is no go-ahead signal, cell will exit cycle and remain in G0
28.
What is an example of an external signal?
Answers may vary, based on presentation: lack of essential nutrient, density-dependent inhibition, anchorage dependence
29.
What are abnormal cells that stay in place called? That invade surrounding tissue?
bening tumors, malignant tumors
