Answer:
Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient.
Explanation:
Ion channels are molecular machines that serve as principal integrating and regulatory devices for controlling cellular excitability. Different types of ion channels have been described: channels that respond to mechanical, electrical (voltage-dependent ion channels), or chemical stimuli (ligand-gated ion channels); ion channels that are controlled by phosphorylation/dephosphorylation mechanisms; and ion channels that are dependent on G proteins. Most ion channels are of the voltage-dependent type and consist mainly of sodium (Na+), potassium (K+), and calcium (Ca2+) channels. Drugs can affect ion channel function directly by binding to the channel protein and altering its function or indirectly through G proteins and other intermediates. Lidocaine is a good example of a drug that directly affects voltage-gated Na+ channels by blocking the channel and thus Na+ entry into the cell.
Thanks! Have a great day!
The DNA is found in the nucleus of the cell
Answer:
Th correct answer is A. Capsid
Explanation:
T-2 phage is a bacteriophage which is virulent to E.coli which means T2 phage infects E.coli. The genetic material of T2 phage is linear DNA which is double-stranded. The genetic material of T2 phage is enclosed in a protein coat which is called capsid.
This capsid protects the genetic material of bacteriophage by any enzymatic digestion, helps the virus to attach the host cell and helps the virion to penetrate the cell membrane of the host cell and inject its genetic material in the host cell. Therefore capsid is the correct answer.
