Answer Qs by providing the proper matches cholera A toxin aquaporin

Solution

Cholera toxin effect:

ANS:

1. Adenyl cyclase (Cholera toxin after cleaving G protein Adenyl cyclase enzyme secretion is increased)

2. Increased (Adenyl cyclase enzyme rate is increased)

3. c AMP (Adenyl cyclase enzyme rate is increase c AMP concentration)

4. Opened (After increasing c AMP concentration, c AMP allows water, Cl and Na ions to outside)

5. Opened (Na channel is also opened along with cl channel)

6. Inhibited (cholera toxin can inhibits absorption via electro neutral sodium-chloride co-transport)

7. Activated (sodium-organic substrate (l-amino acids, d-sugars(glucose)) co-transporters are unaffected by c AMP. sodium- substrate co-transporters is available for absorption of nutrients from internal lumen.

8. Decreased (Increased Na+ flow through channels at the apical end of brush border cells leads to decrease cellular osmotic potential and in Adenyl cyclase enzyme activity it is increased).
