The lock-and-key mechanism refers to
Zinaida [17]
The Lock-and-key mechanism was first proposed by Emil Fischer which described as the enzymatic reactions whereby an enzyme with a single substrate binds temporarily to form a substrate complex. 
The lock-and-key mechanism is usually associated with the complementary shapes of an enzyme with a single substrate, wherein the lock  that is being referred to is the enzyme and the substrate is the key. One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
The active site which is mentioned above is structurally complementary to the substrate. This is the temporary binding site on the enzymes. Just like a lock and key, the enzyme as the lock and the substrate as the key is said to fit together.

Which statement below best summarizes the
monitta

Answer:

D. Clear-cutting would increase the amount of carbon dioxide found in the atmosphere

Explanation:

Plants including trees are organisms that help maintain the balance of carbon in the carbon cycle. They do this via the process of PHOTOSYNTHESIS, which is the way they obtain their energy and carbon source. During photosynthesis, trees (plants) absorb carbon in form of atmospheric carbon dioxide (CO2) from the air through the STOMATA on their leaves.

CO2 is an input substance in order for photosynthesis to occur. In a case where all the trees (plants) of a forest has been clear cut or removed, there will be no organisms to directly absorb the carbon dioxide (CO2) released into the atmosphere via respiration. Hence, the amount of carbon dioxide found in the atmosphere would increase.
