Cell Membrane
What are the 3 components of a cell membrane:
Phospholipid bilayer, receptors, and proteins
What is the difference Active and Passive Transport?
Active takes energy, passive does not
What is the equation for cell respiration?
C6H12O6+6O2→6CO2+6H2O+Energy (ATP)
What are the stages of Mitosis?
PMAT
Where are Stem cells found in the human body?
embryo and bone marrow, intestinal lining, skin
What is a semi-permeable membrane?
lets only certain things pass through
What is Hypertonic vs. Hypotonic vs. Isotonic?
Hypertonic: When the water is going out
Hypotonic: When the water is coming in
Isotonic: When the water is going both in and out
What type of cell respiration makes lactic acid?
Anaerobic Lactic acid fermentation
What is cell death called?
apoptosis
What is a pluripotent stem cell?
Can become certain types of cells, but not all
What diffuses through a cell? What must be facilitated transport? Active transported?
diffusion: water, O2, CO2
facilitated transport: glucose
active: Na+, K+
In potatosmosis, we saw a change in the molarity and the change in mass have a _____________ correlation. explain why
negative. as the molarity of the solution went up, the potato became hypertonic, losing water through osmosis and therefore shrinking in mass
What are the three stages of aerobic cellular respiration?
Glycolysis, Krebs Cycle, ETC
Cancer is the result of uncontrolled _________
mitosis
In an blastula, there are ________ stem cells
multipotent
the movement of water across the cell is called
osmosis
What is the isotonic point of a potato?
around .20M
Explain the difference between the yellow and blue BTB solution results in our yeast lab
Yellow produced carbonic acid from CO2+water combining, causing an acidic pH=yellow. Blue was no cellular respiration, so the H2O stayed nuetral/basic
A cell has 46 chromosomes, it undergoes mitosis, how many daughter cells are formed and how many chromosomes in each?
2 diploid, 46
what are the types of cells called that Henrietta Lacks gave to science? Why was it problematic?
HeLa cells, they took them and made money off of her cells without compensation!
name two types of active transport
endocytosis, exocytosis
A saltwater fish cannot survive in freshwater, explain why
The cells of the saltwater fish have a concentration of salt in them that matches the ocean's salinity, so if put in freshwater, their cells become hypotonic, and they would swell up and die
Draw out the 3 cellular respiration flowcharts
see your notes!
Draw the stages of mitosis
see picture
Can you explain how stem cells form in the human body and how they differentiate?
in embryo, genes send signals to cells to make them differentiate into ectoderm, mesoderm, endoderm. this forms the body layers of the human embryo.
