What is one reason why many geologists did not at first accept the theory of continenal drift ?

Biology

Elodia [21]4 years ago

Explanation:

Continental drift is the theory which states that the continents of the earth moved away from each other over a period of time. It is believed that this theory was opposed by many scientists because they stated that there weren’t enough evidence of mechanism to prove the drift between the continents.

However, it was also rejected because this theory opposed many ongoing geological theories like geosyncline theory, uniformtarism theory even when sufficient evidences were there to prove the continental drift theory.

The mechanism by which the end product of a metabolic pathway inhibits an earlier step in the pathway is most precisely describe
defon

Answer:

The mecanism is termed as feedback inhibition.

Explanation:

In an enzyme catalyzed sequential reaction the end product of that reaction inhibits the activity of the activity of the enzyme catalyzing the ist step This type of  regulation is called Feed back regulation or feedback inhibition.

               The main function of human body is to maintain the homeostasis of the all the components it contains.When the end product of an ongoing enzyme catalzsed sequential reaction is produced in a high lebel at that time to maintain its own homeostatis that end product inhibits the functioning of the enzyme catalzsing the ist step of that biochemical reaction.

For Example Cytidine tri phosphate inhibits the activity of aspartate transcarbamoylase catalyzing the de novo biosynthesis pathway of pyrimidine metabolism.
