Lysosomes are responsible for the degradation of intra- and extracellular proteins.
These proteins are delivered to the lysosome in a number of ways. We will examine the underlying mechanisms for this selective delivery. Mitochondria are critically important, ATP-synthesizing, intracellular organelles. We will introduce the mechanisms by which proteins are imported into these organelles, paying particular attention to the translocation machinery associated with the outer and inner membranes.
