Answer :B. By changing the shape of the enzyme's active site.
check the attachment
Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the active site.
On binding, it disrupts the normal hydrogen bond and hydrophobic interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and ACTIVE SITE of the enzyme (changed it shape).
Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit for binding with the substrate, therefore the efficiency is reduced. No substrate-enzyme complex, and hence no substrate-product complex for the release of products, this brings down the turnover rate and eventually
<u>the rate of reaction of the enzyme</u>
Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves.
The pollutants in 1970 were the highest since recorded history and are declining steadily.
Out of the choices given, the conclusion that can be made is that in both cases, societies were brought into contact through trade. The cultural exchanges that went along with that trade enriched those societies. The correct answer is C.
