Function of enzymes in catalyzing biological reactions Enzymes are catalysts, which are things that increase the rate of a reaction, but does not get used up during the reaction. Structure determines function. A change in structure => a change in function. Important biological reactions catalyzed by enzymes: Metabolism.
The enzyme's shape fits its substrate's shape, thus allowing the enzyme to catalyze the appropriate reaction.

Answer:
The correct answer is option D, that is, bottleneck effect.
Explanation:
A phenomenon, which occurs due to events like earthquakes, floods, or other natural calamities that result in the severe declination in the size of a particular population is known as the bottleneck effect. The bottleneck effect is an extreme illustration of genetic drift that results in the reduction of a population's genetic variability.
With the decline in the size of a specific population, a reduction in the genetic variability of the same population is witnessed due to the loss of alleles. This eventually makes the population vulnerable to pollution and diseases. Hence, the given case is an example of the bottleneck effect.
Answer:
The elevator can store the grain until the right market price, or it can sell it. Country elevators sell their grain to terminal elevators, which clean, separate and maintain the value of the grain. The grain is then sold to flour millers for domestic consumption, or it is loaded into ships bound for overseas markets.
