Why does enzyme activity plateau as substrate
concentration increases?

Answer and Explanation:

Why does enzyme activity plateau as substrate concentration increases?

Simple. The enzyme is saturated, now all available enzyme molecules are busy processing substrates.

Unavailability of Enzymes site

Explanation:

Enzymes are protein that speeds up chemical reaction.

when the substrate concentration is low the reaction rate is low bit an increase in substrate concentration leads to an increase in reaction rate and abundant free enzyme available (E) to bind the added substrate.

When the substrate concentration is high the reaction reaches a stable/ plateau stage as the enzyme active sites become saturated with substrate (ES complex), and no free enzyme site to bind the added substrate.

Reaction plateau because there are no free enzyme site to bind to by the Subtrate this is because all the site are occupied by substrate so an increase in substrate concentration will not increase the reaction rate until there are free enzymes site to bind to by the substrate in the absence the reaction reaches plateau.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
