In E. coli, the presence of isoleucine shuts down the enzymatic pathway that results in the synthesis of isoleucine. This is an example of .

Feed-back inhibition

Explanation:

When the final product of a biochemical pathway signal the inactivation of the starting materials of the pathway, feed-back inhibition is said to have occurred.

In this case, the amino acid, isoleucine signal the inactivation of its starting material. Thus, it is an example of feed-back inhibition

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2
