Peptidoglycan in the bacterial cell envelope is an ideal target for antibiotics because Antibiotics limit bacterial growth and replication by interfering with the bacterial cell wall.
- Penicillin is one of many antibiotics that assault the bacterial cell wall in order to operate.
- The medications specifically stop the bacteria from producing peptidoglycan, a chemical that gives the cell wall the toughness it needs to live in the human body.
- Simply put, a lot of antibiotics, like vancomycin, which like -lactam antibiotics targets the peptidoglycan in the cell wall, are ineffective against,
- Gram-negative bacteria because they lack the molecular characteristics necessary to employ these pathways to efficiently breach the outer membrane.

Answer:The correct answer is " a"
LDL contain protein,triglycerides,phospholipid and cholesterol.
Explanation:
Low density lipoprotein,or LDL,are complex aggregates of lipids and protein.Their function is to transport lipids (fats) around the body,in the bloodstream,and to the cells where its required.Apart from this,it also carries triglycerides,phospholipids and fat soluble vitamins.
Lipoprotein is composed of a hydrophobic core that is made up of polyunsaturated fatty acids and cholesterol molecules,along with a lipid membrane that contains protein called apolipoproteins.
There are 4 major classes of lipoprotein:
•chylomicrons
•very low density lipoprotein(VLDL)
•high density lipoprotein (HDL)
•low density lipoprotein(LDL)
False; Melanin absorbs and dissipates the harmful UV rays that can damage the DNA of your skin cells. Keratin is a fibrous protein that helps to protect skin from abrasion.
Answer:the cell membrane provides protection for a cell
Explanation: that some molecules can diffuse across the lipid bilayer but others no
