Answer: As you've learned, some viruses are released when the host cell dies, and other viruses can leave infected cells by budding through the membrane without directly killing the cell.
Explanation:
Answer:
d. An enzyme will generally bind only one substrate.
Explanation:
Enzymes are the catalytic biomolecules. The enzymes have specific pockets called active sites. Substrates bind to these pockets of enzymes. The active site of an enzyme is compatible to allow a specific substrate to bind to it. This allows specificity to the enzymes and ensures that a specific enzyme binds to a particular substrate only. A substrate can bind to the active site of its enzyme, it can not bind to any other site of the enzyme. Moreover, substrate binding induces a conformation change in the active site of its enzyme to favor the binding of more substrate molecules.
Answer: I think it is D
Explanation:
We learned this already and I dont remember doing d
Answer:
There are a number of mechanisms through which a bacterial cell might become resistant to a specific antibody.
- Some bacteria might posses a cell membrane which wouldn't allow the transfer of antibiotics into the cell of the bacteria. Some bacterial cells might not have the target sites on which the antibiotics attack. A bacterial cell that would be non-resistant wouldn't block the entry of the drug or it might not lack the site where the drug has to function.
- Some resistant bacteria might produce enzymes that would inactivate the activity of the antibiotics. This enzyme machinery would lack in a non-resistant strain. The resistant bacteria might have undergone mutations over a period of time to evolve a machinery for antibiotic resistance.
