Answer:
B. Sodium ions directly enter the cells, indicating the signal is transduced by an ion channel.
D. Sweet utilizes the GPCR signaling pathway, activating phospholipase C.
Explanation:
The taste received by the taste buds is processed through different channels
a) The Sweet, bitter, and umami tastes are transduced by the GPCR (G-protein-coupled receptors) signaling pathway
b) Sour taste reaches the taste bud through the acidification of acid-sensitive membrane proteins with in the taste cell
c) The epithelial sodium channels in the renal tissues directly takes up the salty taste
Hence, option B and D are correct
When water molecules form hydrogen bonds with other molecules, such as carbohydrates, it is called adhesion. It describes the way water moves through the xylem using cohesion (the water molecules stick to each other) and tension (because transpiration is drawing water out of the leaves).
