A lysosome has approximately 50 different hydrolytic enzymes. These enzymes are produced by the endoplasmic reticulum and targeted lysosomes. Lysosome enzymes can digest every type of biological macromolecule. All the enzymes of the lysosome share significant properties – their optical activity at an acid pH and thus are acid hydrolases. The pH optimum of these… Read More »
The Golgi complex has a characteristic morphology – flattened, disklike, membranous cisternae with dilated rims, and associated tubules. The cisternae have a diameter of 0.5 to 1 micrometer, stacked in an ordered manner and a Golgi stack contains fewer than eight cisternae. There are several thousand distinct types of stacks depending on the cell type.… Read More »
The endoplasmic reticulum (ER) is divided into – smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). ER consists of a system of membranes that enclose a space or lumen, that separates it from the cytosol. The composition of the luminal or cisternal space inside the ER membranes is quite different from the cytosolic space.… Read More »
