Imagine that you are observing an enzyme-catalyzed reaction in the lab. Every time you add more enzyme, the reaction rate increa
Aleks04 [339]

Answer:

<u>All the substrates are bound to the enzyme</u>, thats why the reaction rate stopped increasing.

Explanation:

Actually an enzyme works by binding a substrate molecule to its active site, producing a product  , resulting in an increase in the rate of reaction.

            Enzyme + substrate = Enzyme + product

Whenever enzymes are added , reaction rate increases as the substrates are being bound to the enzyme's active sites but then occurs a stage where further addition of enzyme cannot increase the reaction rate because all the substrates have bound to the enzyme and <u>there are no substrates left.</u> Hence the reaction rate stopped increasing.

solniwko [45]

ANSWER:

<u><em>The source of sunlight is the main source of energy and if there will be more sea weed trapping sunlight then there will be a competition between seaweed and coral reef. So, the natural reason for the decreased biodiversity is an overgrowth of the seaweed population which prevents the light from reaching the reef. </em></u>
