If a scientist drops an animal cell into a solution that contains 10 times more salt than is found inside the cell, which of the following will happen? Hint: drawing a picture may help you.
A) The cell will burst since the solution is hypertonic
B) The cell will shrink since the solution is hypotonic.
C) The cell will burst since the solution is hypotonic.
D) The cell will shrink since the solution is hypertonic.
E) The cell will not change in size since the solution is isotonic.
What cell types would be able to grow on the ECM in the following situations?a) Streptomycin was not added to the ECM.b) The ECM contains thiamine.c) The ECM contains all 20 amino acids and all 5 nitrogenous nucleic acid bases.
Reminder: ECM = minimal medium + glucose + has streptomycin antibiotic
Many eukaryote cells are NOT able to synthesize (make their own) the amino acids that they require to conduct life processes. When such a cell is placed in an aqueous (water) solution containing the 20 essential amino acids, one would expect that
a) nothing would happen.
b) amino acids would be moved into the cell by specific membrane transport proteins.
c) H2O would dissolve in the membrane.
d) the cell would make Glucose into amino acids.
e) the cell would divide.

What would you likely classify this bacteria as?arrow_forwardA single celled, prokaryote organism has the ability to use the Na+/K+ pump in their cell membrane to move Na+ out of the cell and K+ into the cell. The Na+ /K+ pump is an example of a functional protein because it a) is a Polypeptide presents specific shapes that interact with (binds with) specific molecules, b) uses electrical interactions with these molecules to produce change in its shape or motion. C) interacts with specific molecules based on the fit of the molecule into specific active sites in the protein, d) As a result of the interaction with specific molecules, it can bind with ATP and use the bond energy in the ATP molecule to move the target molecule(s). e) all the answers are true.arrow_forwardActive transport pumps are used to move sodium ions across the membranes of gill cells in freshwater fish species. Which of the following statements about the pumps is accurate?Explain. a) There are specific binding sites for sodium ions on the pump b) They require osmosis to carry the sodium ions into the cell c) This is an example of passive diffusion and ATP is required d) Their lipid based structure allows it to embed in the cell membranearrow_forward

- While endocytosis and exocytosis refer to the direction in which a vesicle moves into and out of a cell respectively, it is important to think about what is being moved with and within the vesicles. To demonstrate how this process is utilized in human cells we will focus on the human body's insulin response. The purpose of the insulin response is to create a pathway for glucose entry into cells by releasing glucose transporters into the membrane. Cell Type #1- insulin producers: In humans, pancreatic B-cells create steroid insulin that can be packaged into vesicles starting at the ER. These vesicles are prepared for exocytosis so that the insulin can be released from the pancreatic B - cells and get into the bloodstream when signaled to do so. When glucose is present in the blood stream these cells will release the pre-packed insulin into the blood stream. Cell Type #2- insulin responders: Other cells do not produce insulin but instead respond when they have received the insulin signal…arrow_forwardIn the potato osmosis lab experiment what is the point of having multiple potatoes soaking at each concentration.arrow_forwardBacterial growth depends on many environmental factors, including the temperature of the environment. Since microbes can survive in a certain range of temperatures and will thrive at a temperature, understanding these variables allows for control of their growth. This understanding can be used, for example, to preserve certain foods or to treat infections. This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution a) In your own words give an introduction to the microbial growth and the effect tempature has. b) In your own words explain the importance of the spectrophotometer in regards to microbial growth. c) In your own words give a hypothesis on how bacteria will react to different temperatures.arrow_forward
- In cell culture experiments, when you add the purified toxin to host cell monolayers, the host cells die. The toxin-infected host cells do not lyse, but the cells have collapsed and show a significant loss of water and ions. The toxin is translated and produced by the bacterium as a single polypeptide. However, cellular fractionation of the host cells into cytosolic and membrane fractions reveals that a portion of the toxin is present in the membrane fraction and another portion is in the cytosolic fraction. Based on these results, answer the following questions: A. What type of toxin have you identified? 2 B. How does this toxin function to kill host cells?arrow_forwardWhich of the following statements is correct about passive diffusion? Select one: A) It is a process in which molecules move from a region of lower concentration to one of higher concentration (or up a concentration gradient). B) It is a process in which molecules move from a region of higher concentration to a region of lower concentration (or down a concentration gradient). C) It requires an expenditure of energy by the cell. D) It may require a transport protein. E) It involves movement of molecules down a concentration gradient and may require a transport protein.arrow_forwardWhen a prokaryote cell is placed in a hypertonic solution (water with a higher energy level compared to inside the cell), one would expect that H2O would: A) diffuse out of the cell through the lipid section of the phospholipid bilayer B) cause protein synthesis C) move using active transport proteins D) diffuse through Endoplasmic reticulum portal protein E) diffuse through portal proteins of the cell membranearrow_forward
