"describe the mechanism of feedback inhibition and the role this process plays in controlling enzyme activity."

1 answer:

6 0

In biochemistry, feedback inhibition occurs when the end product produced by the reaction using an enzyme, interacts with the enzyme again such that it inhibits the initial reactants. This is important in metabolic reactions to control too much production of amino acids or too much work done by enzymes to break down macromolecules.

The study of nutrient cycling though the environment is an example of which of the following?

Oliga [24]

Answer:

ecosystem ecology

Explanation:

The ecosystem is the basic unit for supporting life, but an ecosystem goes beyond organisms living in one place. Life depends on the recycling of resources between organisms and the environment in which they live, between organic and inorganic forms. Ecosystem ecology studies these transformations and integrates into both terrestrial and aquatic ecosystems, attracting fields as diverse as atmospheric chemistry, hydrology, soil science, physiology, and ecology.

For this reason, The study of nutrient cycling through the environment is an example of subjects that are studied in ecosystem ecology.

They have also observed the growth of plantlike organisms in the bay. Which is the most likely explanation for the results? A. T

forsale [732]

Answer:

This question is incomplete as it does not contain the graphical representation of fishes population over time. The image containing this information has been attached in the attachment section.

The correct answer is D. The nitrogen from the fertilizer made the plants grow too quickly, which hurt the fish.

Explanation:

According to the attached image, artificial fertilizer is being used on a an apple orchard for six years. The orchard is located near a stream which runs out into a small bay.

Based on the results of the sampled population of fishes for five years as represented graphically by researchers (see attached image), it is obvious that the population of the fishes in the bay is reducing over the years. They also observed the growth of plantlike organisms in the bay.

The possible cause of this decline in the population of fishes is the increased growth of these plantlike organisms. The plantlike organisms are algae, which uses the nitrogen content of the artificial fertilizer that washes into the bay from the orchard, as a source of nutrient. This excessive nutrient causes the plantlike organisms to bloom or grow too rapidly- a process called EUTROPHICATION.

Eutrophication causes the oxygen content of the bay to reduce gradually as the blooming of the plantlike organisms depletes oxygen in the water body, thereby, harming aerobic aquatic organisms like fishes in the bay.

Hence, in a nutshell, the reduction in the population of fishes in the bay is as a result of the nitrogen from the fertilizer which made the plantlike organisms grow too quickly, leading to oxygen-depletion and subsequently death of the bay fishes.
