The remodelation of osseous tissue,
the of acrosomes in cells
and the of the tadpole
are examples of processes in
which enzymes are key
.

The bone is tissue made of
containing matrix (osteoblastsare
secretory cells of osseous matrix),
osteocytes ( bone cells) and
(the remodeling cells).
are responsible for
continual renovation of osseous
tissue since lysosomic enzymes
digest osseous matrix.

The acrosome, for carrying
enzymes within, is
for the perfuration the egg cell
in the fertilization .
The acrosome, located the anterior
end the sperm cell, a specialized
region the Golgi apparatus
accumulates a great of
digestive enzymes.

tadpoles the tail while the
organism into an adult .
This tissue destruction a digestion of
tail's own cells extracellular
materials and is made by
and their enzymes. complete
digestion of cell by its
mechanisms is called , a type
of (cell suicide).
