The hyphae stretch into the growth medium and release enzymes (e. g.) to break down molecules in the environment and absorb nutrients.

See the answer below

Explanation:

The hyphae stretch into the growth medium and release enzymes (e.g. protease) to break down molecules in the environment and absorb nutrients.

The hyphae of fungi generally strech into the media on which they grow and release enzymes to break down molecules in the media environment and absorb digested substances containing nutrients. The enzyme released depends on the nature of molecules found in the media. Proteolytic (e.g protease), glycolytic, or lipolytic enzymes are released to digest protein, carbohydrate, or lipid respectively.
