Viruses lack the properties of living things:
1. They have no energy metabolism
2. They do not grow
3. They do not respond to stimuli
4. They do not reproduce independently- they have to replicate by invading living cells.
Explanation:
Both prokaryotic and eukaryotic cells have:
DNA.
Ribosomes.
Cytoplasm.
Plasma membrane.
The ATP enables the movement of transport proteins to move the ions across a cell membrane by its getting fueled by its hydrolysis
<u>Explanation:</u>
The plasma membrane is a semi permeable membrane that is the movement of molecules across the membrane is constricted. There are 2 types of moment across the plasma membrane one is the active transport and the other is the passive transport. The active transport involves the help of ATP whereas the passive transport does not involve ATP to transport the materials.
Answer:
Allosteric inhibition can be reversed.
The allosteric inhibitor binds to a site distinct from the active site resulting in decreased affinity of the enzyme for the substrate.
Allosteric inhibition can be irreversible
Answer:
a. preventing the cross-linkage of NAM subunits
Explanation:
The bacterial cell wall is made of peptidoglycan which is a polymer of alternating N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) residues. The NAM residues are crosslinked to impart additional strength to the cell wall.
Most of the antibiotics that target the cell wall synthesis in bacteria inhibit the enzyme of transpeptidation which in turn cross-links the NAM residues of the polysaccharide chains of the bacterial cell wall. Examples of these antibiotics include penicillins and cephalosporins.
