In the absence of tension, MscL channel has an energy gap separating the closed and open states Eo = 50 kT. MscL opening is associated with a 20 nm2 in-plane protein expansion (DA). Using Excel plot its open probability (Po) as a function of membrane tension and paste the graph below. What will be the open probabilities of two MscL channels if one situates at the pole of the bacterial cell above, another in the middle?
A 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.

TRANSLATION: Antibiotics are drugs that are bacteriostatic or bactericidal. Both antibiotic types may be used to effectively eliminate an infection. Bacteriostatic antibiotics prevent bacterial growth and require higher dosages to eliminate the infection. Bactericidal antibiotics kill bacterial cells at lower dosages. A common cellular function that is targeted by antibiotics is the process of translation, since the ribosome and other factors involved in translation are different in prokaryotic cells versus eukaryotic cells. Thus, the antibiotic is specific only to bacteria and does not harm the host. Chloramphenicol is an antibiotic that blocks the enzyme, peptidyl transferase. This enzyme is responsible for forming peptide bonds between amino acids during the process of translation. Answer the following questions about chloramphenicol. a.
