Hydrolytic enzymes break down protein, carbohydrate, and fat molecules into their simplest units. The hydrolysis of polymers by hydrolytic enzymes results in free monomers.
s enable the acrosomal process to penetrate the egg's jelly coat.
The tip of the acrosomal process adheres to special receptor proteins on the egg's surface.
Lysosomal hydrolytic enzymes are manufactured in the rough endoplasmic reticulum (Rough ER), from whence they are transferred in a transport vesicle to the cis face of the Golgi apparatus or complex (see Figure 1).

In biochemistry, a hydrolase is an enzyme that catalyzes the hydrolysis of a chemical bond. For example, an enzyme that catalyzed the following reaction is a hydrolase: ...
Those enzymes are called hydrolytic enzymes, and they break down large molecules into small molecules. For example, large proteins into amino acids, or large carbohydrates into simple sugars, or large lipids into single fatty acids.
Lysosome: Lysosomes contain s necessary for intracellular digestion. They are common in animal cells, but rare in plant cells. s of plant cells are more often found in the vacuole.
(b) Unlike animals, "A fungus digests food outside its body by secreting powerful hydrolytic enzymes into the food. The enzymes decompose complex molecules to the simpler compounds that the fungus can adsorb and use." ...
Vesicles in the cell which contain s. Pronounce:

However, one lysosomal storage disease, I-cell disease ("inclusion-cell disease"), is caused by a failure to "tag" (by phosphorylation) all the hydrolytic enzymes that are supposed to be transported from the Golgi apparatus to the lysosomes.
Lysosomes are relatively large vesicles formed by the Golgi. They contain s that could destroy the cell. Lysosome contents function in the extracellular breakdown of materials.
lysosome /LIE-sə-SOAM/ A eukaryotic membrane-bounded vesicle containing hydrolytic enzymes, that engulfs and breaks down macromolecules in the cell that require digestion.
(ly-so-some) [Gk. lysis, loosening + soma, body]
A membrane-enclosed bag of s found in the cytoplasm of eukaryotic cells.
lysosome Cytoplasmic, membrane-bounded organelle that contains digestive and hydrolytic enzymes, which are typically most active at the acid pH found in the lumen of lysosomes.
Resulting glucose diffuses into the cytoplasm of epithelial cells
Glucoseis also released back into the intestinal lumen and absorbed further down
Thus, duodenum digests food by s (→H2O) ...
and a poly-A tail (50 to 250 adenines) is added to the 3'end of the molecule. These modifications are thought to 1) enhance the movement of mRNA through the nuclear pores into the cytoplasm, 2) prevent the destruction of mRNA by hydrolytic enzymes, ...
Despite this general belief, neither Justus Liebig nor Ernst Hoppe-Seyler, two eminent chemists, accepted this view. s such as amylase, maltase, and pepsin were known in the nineteenth century, ...
