Which is more sensitive to penicillin gram posite or gram negative?
Gram-positive bacteria are generally more sensitive to penicillin compared to gram-negative bacteria. This is because gram-positive bacteria have a thinner cell wall that is easier for penicillin to penetrate and disrupt, leading to cell death. Gram-negative bacteria have an outer membrane that provides some protection against penicillin, making them less susceptible.
Does penicillin kill gram negative or gram positive or both?
Penicillin primarily targets and is more effective against gram-positive bacteria by disrupting their cell wall synthesis. It is less effective against gram-negative bacteria due to the presence of an outer membrane that restricts penicillin's access to the cell wall.
Are penicillin binding proteins found in gram positive and gram negative bacteria?
Yes, penicillin binding proteins (PBPs) are found in both gram positive and gram negative bacteria. PBPs are enzymes involved in cell wall biosynthesis and are the target of beta-lactam antibiotics like penicillin.
Which are more sensitive to penicllin?
Gram-positive bacteria are generally more sensitive to penicillin than Gram-negative bacteria. This is because the cell wall of Gram-positive bacteria is more susceptible to the action of penicillin, while Gram-negative bacteria have an outer membrane that provides some protection against the antibiotic.
Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.

What illness is penicillin prescribed for?
Penicillin is prescribed for numerous illnesses. In general penicillin is used as an antibiotic to kill bacteria. Penicillin is used against bacteria that contain a cell wall that is considered "gram positive", which means the cell wall is comprised of a thick layer of peptidoglycan. Penicillin chemically prevents the linking of protein subunits in the cell wall which means the cell wall can not be assembled. Bacteria are very dependant on these cell walls to maintain osmotic pressure within the cell (primarily due to their small size). If it can not create and maintain this cell wall the bacteria fills with water and bursts, destroying the cell. While gram-negative bacteria do respond to a minor degree to this mechanism of action, it would be considered less appropriate to treat a gram-negative bacteria infection with penicillin due to the
Why are Gram-positive bacteria more susceptible to the effects of penicillin than Gram-negative bacteria?
Penicillins have a bacteriocidal effect on Gram-positive bacteria. In Gram-positive cells, peptidoglycan makes up as much as 90% of the thick, compact cell wall, and is the outermost layer. Penicillins are not effective against Gram-negative bacteria, which have cell walls in which peptidoglycan is not the outermost layer, but that lies between the plasma membrane and a lipopolysaccharide (LPS) outer membrane. Penicillin cannot access the peptidoglycan of Gram-negative cells.
How do protoplast differ from L form?
Protoplasts are formed from gram-positive cells in the presence of lysozyme, which destroys the cell wall. L forms are gram-positive or gram-negative bacteria that do not make a cell wall. Therefore, L forms never had or made a cell wall as opposed to protoplasts which used to have a cell wall, but no longer do because it was destroyed. Penicillin can be used to destroy the cell wall of a bacterial gram-positive cell and form a protoplast, but in the presence of Penicillin, if a new bacterial cell is forming and cannot create a cell wall, then it will become an L form.
Is the anode positive or negative in an electrolytic cell?
In an electrolytic cell, the anode is positive.
What is penstrep?
Penstrep is a combination antibiotic solution of Penicillin and Streptomycin commonly used in cell culture to prevent bacterial contamination. It helps to inhibit the growth of a wide range of Gram-positive and Gram-negative bacteria, ensuring the purity of cell culture experiments.
Is the anode positive or negative in a galvanic cell?
In a galvanic cell, the anode is the negative electrode.
Is the anode positive or negative in a voltaic cell?
In a voltaic cell, the anode is the negative electrode.
