increasing intracellular cAMP leads to smooth muscle relaxation by: Group of answer choices inhibiting IP3 channels, leading to
kirza4 [7]

Answer:

1. Inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction.  

2. Increasing the relative activity of MLCP, leading to a decrease in tension.

3. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry.

Explanation

In smooth muscle, cyclic AMP (cAMP) mediates relaxation because cAMP inhibits a specific kinase required for myosin light chain protein (MLCP) phosphorylation, thereby triggering contraction in the smooth muscles. It has been shown that cAMP inhibits 1,4,5-trisphosphate (IP3)-dependent calcium ions (Ca 2+) release by activation of the cGMP-dependent protein kinase (PKG). PKG proteins act to modulate Ca2+ oscillations by stimulating sarcoplasmic Ca2+-ATPase membrane proteins, increasing Ca2+ in the sarcoplasmic reticulum stores and Ca2+ efflux from the cells, and activate voltage-gated potassium (K) channels, thereby leading to membrane hyperpolarization and reducing Ca2+ entry through Ca2+ channels.

What are some possible consequences if transgenic salmon escape from their pens into the ocean population?
babunello [35]

Answer:

If the transgenic salmon escapes from their pens into the ocean population there are chances that they would compete with the wild salmons for food and space. They may also bring new diseases and changes to the food webs and ecosystem of the ocean.

Explanation:

A transgenic organism or genetically modified organism is the one that undergoes alternation through recombinant DNA technology.

No, I do not think that FDA should approve Aquabounty of growing and selling transgenic salmon since there is higher chance that they may interfere and disturb with the ecosystem and might also bring new diseases.
