Answer:
The correct answer is option (b) "addition of a drug that prevents the α subunit from exchanging GDP for GTP".
Explanation:
The G protein is a name given to a family of proteins that act as a switch in diverse cellular processes, transmitting signals from outside to inside of the cells. When a G protein receptor is activated by a neurotransmitter such as dopamine, the alpha subunit exchanges its GDP for a GTP and disassociates G-protein itself. An addition of a drug that prevents this action would prevent G protein disassociation, which would enhance the effect of stimulating G protein that acetylcholine does.
Answer: pretty sure it’s B.
Explanation: The salivary glands create a digestive juice called salivary amylase that starts to break down or hydrolyze the starch that is in the bread of the chicken sandwich when the chicken sandwich first reaches the mouth. It would be digested in the amylase in the stomach
