Why are drugs that target cell wall synthesis useful?
Without the cell wall, the bacteria will be susceptible to destruction by chemicals outside the plasma membrane (which is just inside the cell wall of bacteria), and it will not be able to survive.
Most anticancer drugs such as the antimetabolites. alkalating agents and platinum based drugs target the S-phase of the cell cycle ( DNA replication/synthesis phase) Other drugs like the antimicrotubules target the G2-M phase of the cell cycle
By directly causing protein synthesis
Single amino acids are found in the cytoplasm of the cell. They are mainly useful in protein synthesis, although they have other uses.
rough endoplasmic reticulum transports protein synthesis by Ribosomes.While smooth endoplasmic reticulum synthesis lipids and centre for detoxification of drugs
Aminoglycosides such as streptomycin target protein synthesis. The antibiotic drug, streptomycin, was the first successful cure in the treatment of tuberculosis.
Penicillin destroys cell walls of bacteria by interfering with the formation of Peptide cross-bridges of peptidoglycan to prevent the formation of an active cell wall.
Why do antibiotics that interfere with cell wall synthesis have a high specificity and are more likely to be low in toxicity to host organisms?
They have a high specificity because the main target with regard to bacterial cell wall synthesis is peptidoglycan. This is not endogenous to humans and thus drugs which interfere with cell wall synthesis in bacteria are rather specific. The normal types of drugs that act in this way are penicillins or beta lactam drugs. They are bacteriocidal as they break down cell walls of existing bacteria. There exact mechanism of action is; they bind to… Read More
Hormones can (1) direct the synthesis of an enzyme (or other protein) not already present in the cytoplasm, (2) turn an existing enzyme "on" or "off," and (3) increase the rate of synthesis of a particular enzyme or other protein.
Packaging of secretory proteins as well as the synthesis of lipids. also responsible for inactivation and detoxification of drugs and other compounds that might otherwise be harmful or toxic to the cell.
The ribosomes are the cell organelles which are involved in protein synthesis.
Protein synthesis occurs on ribosomes found in the cell.
The site of protein synthesis, within the cell, are the ribosomes.
Ribosomes are small ''protein factories'' for protein synthesis in cell. Therefore, cell use ribosomes for synthesis protein...
Cell transportation is vital for the cell because the cell needs a mechanism to purge waste out of the cell, to take in useful substances, and to transport substances within the cell. If cell transportation did not exist, then substances would fail to reach their target destinations inside, or outside of the cell.
Protein Synthesis takes place in the ribosomes and in the mitochondria of a cell.
A cell will know when to start protein synthesis when the RNA will get to the ribosome. The ribosome is described as the protein factory in the cell.
Malaria is a single-celled protozoan parasite and is not a bacterium. This means it does not have cell walls unlike bacteria. Penicillin and other beta-lactam antibiotics kill bacteria by stopping the repair and remodeling of the bacterial cell wall through inhibition of peptidoglycan synthesis, which is necessary to maintain the cell wall. Other classes of antibiotics, particularly tetracyclines, however, can work against malaria because they target a function that is present in both bacteria and… Read More
The Smooth ER is the "hallways" of the cell, that lead products to the Golgi appratus. It synthesis lipids, metabolizes carbohydrates, and detoxifies drugs and poisons. It also stores calcium ions, which are necessary for muscle movement.
Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin binding proteins (PBPs); which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thus inhibiting cell wall biosynthesis. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested. source:(http://www.umm.edu/altmed/drugs/ampicillin-006800.htm)
Any antibiotic interfering with cell wall synthesis would not have an effect because mycoplasmas do not have a cell wall.
Within the Cell cycle, Dna synthesis occurs during the S [synthesis] phase.
During protein synthesis a eukaryote cell has several structures that help the cell maintain homeostasis, and provide energy and the mechanisms for protein synthesis.
Why is the presence of ergosterol rather than cholesterol an important difference between fungal cells and your own?
Ergosterol, a cell membrane sterol, is found in the cell membrane of fungi, whereas the predominant sterol of bacteria and human cells is cholesterol. Anti fungal medications can bind to the ergosterol and create holes in the membrane allowing lysis of the cell or a secondary drug can be used to inhibit DNA and RNA synthesis. Some other drugs can inhibit ergosterol synthesis and also disrupt the cell membrane.
Synthesis occurs in the cytoplasm by the ribosomes
should science pursue the synthesis of a living cell. Yes or No. Explain
Most new membrane synthesis in a eucaryotic cell takes place in the mitochondria.
The site for protein synthesis is a cell structure. The specific structure in which synthesis occurs is the ribosomes, which is in the cytoplasm.
Mycoplasma lack cell walls. Therefore, any antibiotic that targets the cell wall of bacteria would be ineffective to mycoplasma. Examples are beta-lactam antibiotics such as penicillin. Beta-lactam antibiotics target the synthesis of peptidoglycan, an important component of the bacterial cell wall.
aNAINST ANTIBIOTICS: Inhibition of Cell Wall Synthesis (most common mechanism) Inhibition of Protein Synthesis (Translation) (second largest class) Alteration of Cell Membranes Inhibition of Nucleic Acid Synthesis Antimetabolite Activity
Ribosomes do the work of protein synthesis for the cell.
It is the Smooth Endoplasmic Reticulum. The Smooth ER is the "hallways" of the cell, that lead products to the Golgi appratus. It synthesis lipids, metabolizes carbohydrates, and detoxifies drugs and poisons. It also stores calcium ions, which are necessary for muscle movement.
In terms of organelles, the mitochondria are scattered throughout the the cell and is a major site of ATP synthesis, also known as the "powerhouse of the cell"
how can protein synthesis affect cells? what is the result?
Inhibition of cell wall synthesis disruption of cell membrane function inhibition of protein synthesis inhibition of nucleic acid synthesis anti-metabolite actions
the nucleus is the brain of the cell, where protein synthesis begins. endoplasmic reticulum and Golgi apparatus are for protein synthesis. the mitochondria gathers energy for the cell the cell membrane allows waste out and nutrients in
In the cell, the endoplasmic reticulum which contain ribosomes is the site for protein synthesis. Afterwards, the proteins undergo the translation process.
It is a site for active ribosomal RNA synthesis larger and more numerouse nucleoli are present in cell actively carrying out protein synthesis
Ribosomes helps the cell to protein synthesis.
The ribosomes of the cell produce proteins.
Protrin synthesis occurs in two steps transcription & translation Transcription occurs in Cell wall & Translation occurs in ribosomes
Protein synthesis takes place because much of the cell structure is made of proteins, and proteins regulate cell processes.
DNA synthesis, RNA synthesis and cell reproduction
They work by inhibiting bacterial cell wall synthesis by inhibiting peptidoglycan synthesis
Protien synthesis occurs in a cell because protein is basically the building block of cells. It has so many functions inside them, like bringing in substances and repairing a cell.
Ribosomal-based protein synthesis takes place in the cytoplasm of the cell. Peptides are synthesized by the ribosomes, typically on the rough ER of the cell.
Endoplasmic reticulum because ribosomes are present in it OR we can also say the cell organelle ribosomes because they are sites of protein synthesis
nucleus fuction as control house of the cell. it perform all the major function for the cell, it controls protein synthesis, dna replication, hormone synthesis.
Antibiotics are designed to target or attack parts of a bacterial cell, like the cell wall, or enzymes contained inside the cell; viruses do not contain the same cell pieces, or machinery, so antibiotics cannot attack them. Antivirals are a class of drugs designed to attack virus parts.
On the ribosomes in the cytoplasm of the cell and in the mitochondria
Synthesis is the first stage of the cell cycle
