The gestation period in cats stays for approximately 66 days and in every cycle a cat give birth more than 2 babies so if all cats are producing kittens at this rate, a prediction can be made that there will be lots of cats in our ecosystem. There will be cats everywhere if the number is not controlled.
As mentioned earlier, cats can starts reproducing at a young age of 6 months and right after delivery can get pregnant.
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!
