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.
Answer:
As the Ecological Footprint refers to continuous demand, and biocapacity refers to a continuous supply, both are correctly reported in global hectares. In the case of activity with a discrete start and end, such as the creation of an individual product, a different unit is required.

well thats how I remember it anyway
SO ITS NUMBER 2
