What is the movement across the cell membrane which does not require the cell to exert any of its energy to accomplish the movement?
Passive Transport
100
What organelle sets eukaryotic cells apart from prokaryotic cells?
Nucleus
100
What major event occurs during M phase of the cell cycle?
Mitosis (cell division)
100
What type of cell is produced by mitosis?
Somatic dipliod cells
100
What is the only tranportation protein that uses ATP to function?
Pump
200
What two properties of a molecule have the greatest impact on how quickly it can cross a cell membrane?
Size and Charge
200
What structures are found in both plant and animal cells? (name as many as you can)
Mitochondria
Nucleus
Cytoskeleton
Endoplasmic Recticulum
Ribosomes
Cytoplasm
Golgi Body
200
Why are G1 and G2 of the cell cycle called gap phases?
these phases focus on growth and checking before DNA replication(S) or cell division(M)
200
What are the two reasons daughter cells produced by mitosis genetically identical?
DNA replication
Separates sister chromatids
200
You encounter a cell with multiple Rough ER and Golgi bodies. What is a possible function of this cell defend your answer.
Protein production and transport
300
What are the four main components of a cell membrane?
Peripheral proteins
Integral Proteins
Oligosaccharide (carbohydrate)
Phospholipid Bilayer
300
You observe a cell with many chloroplast and mitochondria. Based on this information where will you most likely find this cell?
this is a plant cell, most likely found in a plants leaves.
300
What are the stages of the cell cycle in order?
G1(G0)-S-G2-M
M-G1(G0)-S-G2
300
In this micrograph, we can see a cell undergoing mitosis. The chromosomes are being pulled toward opposite ends of the cell. What stage is this, and what is happening to the chromosomes?
:max_bytes(150000):strip_icc()/meiosis_anaphase_1-56a09b4c5f9b58eba4b2052b.jpg)
this cell is undergoing anaphase, sister chromatids are being pulled apart by cytoskeletal filaments, their connection protein is breaking down and they are being pulled to opposite poles of the cell.

O-C H+ 
Put these molecules in order from fastest to slowest to cross a cell membrane with no transportation protiens
4-2-3-1

A scientist researching cell membranes encounters a transport protein which binds to amino acids and changes shape to move them through the membrane. What kind of transport protein is this and does it use active or passive transport?
This is a Carrier protein which uses no energy
400
What are the three cytoskeletal elements and what are their main functions?
Actin filaments- cell movement and structural support
Intermediate filaments- structural support for organelles
Microtubules- transportation of materials around the cell
400
Why does chromosome replication have to occur in interphase. What would happen to daughter cells if replication didn't occur?
chromosome replication must occur before so each daughter cell receives a complete set of chromosomes.
If this replication did not occur daughter cells would only have half the number of chromosomes. They would be missing genes needed for proper functioning and survival and would likely die.
400
A cell has a diploid number of 8 chromosomes, after replication how many chromatids does this cell have?
16 chromatids
400
What would happen to a cell if both p53 genes were mutated?
p53 is an important tumor suppressor
Without p53, cells lose a major protection against mutation accumulation, making cancer development much more likely.
500
What property of phospholipids cause small ions like H+ to need facilitated diffusion to get through a cell membrane?
Hydrophobic(nonpolar) Tails
500
A genetic mutation damages all of a cell's mitochondria so they can no longer produce ATP. What would happen to active transport processes in this cell?
THey would stop, because ATP is required for active transport.
500
What is cancer's relationship to mutations? Why are older people more likely to get cancer than younger people?
Cancer is caused by an accumulation of mutations affecting cell division.
As people age more mutations accumulate, causing a higher probability of cancer.
500
Why are the daughter cells produced by mitosis genetically identical?
DNA Replication
Sister Chromatids Separate
500
Researchers develop a new cancer drug which prevents cells from progressing past the G2 check point. Would this be an effective treatment for cancer, if so why?
Yes, G2 checks that cells DNA has been accurately replicated before mitosis. So this drug would prevent cells with dna mutations to multiply.
