Discuss how defective G protein function is associated with cholera.

Dvinal [7]

Answer:

The function of G-Protein’s become defective and abnormal after the addition ADP-ribose to the G protein by the A sub unit. this phenomenon is called as ADP-ribosylation which result in the permanent activation of G-protein . When the G-Protein become active, the enzyme adenyl cyclase converts ATP into cAMP. Increase concentration in the cAMP blocks the transportation of sodium from the lumen into the bloodstream. the amount of Chloride and bicarbonate also increases. Due to the continuous increase of the ions, water moves into by osmosis from the bloodstream and cholera occurs.

1.Write the part of the brain that preforms each of the functions shown below.

Damm [24]

The parts of the brain of a living organism which perform each of the functions are listed as follows:

Hypothalamus: it regulates sleep.

Optic nerve: it connects brain and eyes.

Cerebellum: it controls balance.

The frontal lobe: it controls thinking.

The brain stem: it controls breathing and heart rate.

The nucleus accumbens: it is the pleasure center.

<h3>What is a brain?</h3>

A brain can be defined as an organ of soft-nerve tissue that is found within the skull of vertebrates, and it's mainly responsible for the coordination of nervous activities, sensation and intellect in living organisms.

Based on scientific records and information, the two (2) sides of the brain (symmetrical left and right hemispheres) are able to communicate through the corpus callosum.

In conclusion, we can infer and logically deduce that the parts of the brain of a living organism which perform each of the functions are listed as follows:

Hypothalamus: it regulates sleep.

Optic nerve: it connects brain and eyes.

Cerebellum: it controls balance.

The frontal lobe: it controls thinking.

The brain stem: it controls breathing and heart rate.

The nucleus accumbens: it is the pleasure center.
