Which of the following statements best describes the role of adenylyl cyclase in the epinephrine signaling pathway?
Nesterboy [21]

Answer:

It accelerates the production of a second messenger.

Explanation:

Adenylyl cyclase is an enzyme capable of converting ATP molecules into cyclic adenosine monophosphate AMP (cAMP). The cAMP molecule is considered to be a second messenger that transfers the hormonal signal (i.e., epinephrine) inside the cell. Subsequently, cAMP activates molecular signaling events by binding and thus activating cAMP-dependent protein kinase A (PKA). Finally, this last protein (PKA) phosphorylates different proteins that control many diverse cellular processes.

Which chromosomal defect is caused when part of a chromosome breaks off and reattaches backward on the same chromosome?
Y_Kistochka [10]
Deletion is when a part of the chromosome is deleted. (Removed)
Insertion is when part of our chromosome has an extra bit added to it.
Translocation Is when one part of the chromosome is moved to another chromosome.

The correct answer is inversion, to invert means to turn upside down. So when part of the chromosome is taken off but attached backwards (turned upside down) we call it inversion

Hope that makes sense
