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.
Normally, it would take approximately 59 minutes to burn off a slice of peperoni pizza. Most of us walk roughly three miles per hour.

Hyphae absorb nutrients from the environment and transport them to other parts of the thallus.
Explanation:
The large volumes of hyphae within the mycelium perform a fundamental role by obtaining nutrients from the organic substrates from the surrounding of the fungus. Hyphae play different kinds of functions in fungi.
They contain cytoplasm or cell sap. They also contain the nuclei, which include genetic material. Hyphae absorb nutrients from the environment and transport them to other parts of the thallus.
The thallus is the fungus body in which the fungi live or from beneath the soil to give support to the fungi for its growth and its survival.
