The transition from the closed to the open complex involves structural changes in the enzyme and the opening of the DNA double helix to reveal the template and nontemplate strands. This “melting” involves

A. Isomerization reaction and it does not require energy derived from ATP hydrolysis

B. Isomerization is essentially irreversible and, once complete, typically guarantees that transcription will subsequently initiate

Choose correct statements about Muscarinic receptors;

a. An acetylcholine analog, In activated condition, these receptors slow the rate of heart muscle contraction.

b .This type of receptor is coupled to a Gαi protein, and ligand binding leads to the opening of an associated K+ channel.

c .The subsequent influx of K+ ions from the cytosol causes an increase in the magnitude of the usual inside-negative potential across the plasma membrane that lasts for several seconds.
