A chemical engineer wants to design a novel enzyme that is capable of catalyzing a reaction in a hydrocarbon solvent instead of
aalyn [17]

Answer:

A few obstacles would make it tough to accomplish this objective. In the first place, the polypeptide backbone is characteristically polar. Hardly any proteins would be dissolvable in a non-polar hydrocarbon. Moreover, to keep up the dissolvability of this protein, most of its amino acids would need to contain hydrophobic or non-polar R groups.

Then again, its charged or polar R groups would need to connect with one another or be covered in the core of the protein away from the hydrocarbon solvent. This would put noteworthy requirements on both the idea of the R groups and the structure of the protein that could take part in substrate recognition or catalysis. By and large, this is certainly not a reasonable objective.

What is not an example of negative feedback
svetoff [14.1K]
<h2>Answer:</h2>

<u>Blood clotting</u> is a positive feedback.

<h2>Explanation:</h2>

All the physiological process occurring in the body are monitored by two types of mechanism called negative feedback and positive feedback.  

Positive feedback is the reaction which occurs with the feedback from the actions the system has performed. The blood clot occurs with palette formation which is regulated with the blood lose (continuous feedback).

Negative feedback is a reaction that is the invert of the change distinguished, meaning it capacities to decrease the change. A change is recognized by a receptor and an effector is made to incite a contrary impact which facilitates further reaction.  

The physiological process such as shivering, sweating and digestion are examples of negative feedback.
