cAMP is the second messenger in the pathway.
cAMP or Cyclic AMP is a secondary messenger because it transmits signals from a receptor to a target cell. When the level increases rapidly, it starts following receptor-mediated activation of AC (adenylyl cyclase), and that catalyzes the conversion of AMP (adenosine monophosphate) to cAMP.
The cAMP pathway is also known as the adenylyl cyclase pathway, which is a G protein-coupled receptor that is used in the cell signaling process. It works by activating protein kinase A. Therefore, cAMP is considered a secondary messenger which also regulates various cellular functions like cell growth, cell differentiation, etc.

We cannot drink water and water can damage the ecosystem. Water pollution can be reduced by adding filters to rivers.
It means that the cell must only let in certain items and must only allow a certain amount of something into the cell
Answer:
Prophase
Explanation:
DNA is condensed and pairs of homologous chromosomes exchange sections of DNA.
Answer: No
Explanation:
Carbonic anhydrase (CA; carbonate hydro-lyase) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<-->HCO3(-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.
The zinc ion is located in a cone-shaped cavity and coordinated to three histidyl residues and a solvent molecule. Inhibitors bind at or near the metal center guided by a hydrogen-bonded system comprising Glu-106 and Thr-199. The catalytic mechanism of CA II has been studied in particular detail. It involves an attack of zinc-bound OH- on a CO2 molecule loosely bound in a hydrophobic pocket. The resulting zinc-coordinated HCO3- ion is displaced from the metal ion by H2O. The rate-limiting step is an intramolecular proton transfer from the zinc-bound water molecule to His-64, which serves as a proton shuttle between the metal center and buffer molecules in the reaction medium.
