How does a lysosome recycle materials in a cell?
A
It synthesizes new proteins on its surface using ribosomes and exports them to the cytosol.
B
It uses acid hydrolases to break down macromolecules into monomers that are transported back to the cytosol for reuse.
C
It generates ATP through oxidative phosphorylation and uses the energy to rebuild damaged organelles.
D
It packages newly made lipids and proteins into secretory vesicles and releases them outside the cell.
