What are lysosomes? what types of molecules would be found inside lysosomes?

The lysosomes are membrane-enclosed organelle, usually spherical. They contain a number of hydrolytic enzymes that are able to break down dfferent kind of molecules. However, to maintain the optimal conditions for enzymes to perform their function, pH in the lysosomes must bi acidic and thus maintained between 4.5 and 5.0. Apart from hydrolytic enzymes, the lysosomes contain substances involved in cell signaling and energy metabolism.
