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
Answer:
Theta - would be unable to initiate
rolling circle - could proceed without primase
Explanation:
Primase is an enzyme involved in the replication of DNA and catalyzes the synthesis of Primers(Short RNA segments)
Bacterial replication can be by theta or Rolling circle.
In theta replication primers are to initiate replication, without primase there will be no primers hence replication will not be initiated.
Rolling circle is in circular DNA and replication is initiated by an initiator protein encoded by plasmid therefore the process will proceed without primase.
All the normal cells in the human body have the same number of chromosomes because all of their DNA is the same.
