Lysosomes.
My AP Biology teacher back in high school used to give us the mnemonic "Lysis slices"; so if you remember that rhyme, you can remember that the lysosomes cut food particles (and yes, worn-out organelles) to parts base enough to be useful.
lysosomes
It is called cellulose. Human lack enzymes to digest it.
Yes
Enzymes are proteins, which are comprised of chains of amino acids. All enzymes are proteins (but not all proteins are enzymes)
Catalysts that are active working in the body are called enzymes.
Three enzymes are important: pepsin, trypsin, chymotrypsin.
Synaptic vesicles are found in the axon terminals of nerve cells.
The digestive organelles of a cell are - peroxisomes, vesicles/vacuoles and lysosomes.Peroxisomes are single membrane sacs that contain digestive enzymes that break down toxic materials in a cell. They also break down fatty acids to sugars.Vacuoles/vesicles are found in plant cells and some animal cells. Vacuoles and vesicles are membrane bound but the vacuoles are stationary and vesicles can move within the cell.Vacuoles are of three different types - food vacuoles, contractile vacuoles and central vacuoles.food vacuoles are involved in ingesting food into the cell through a process called phagocytosiscontractile vacuoles are found in fresh water protists and are involved in pumping excess water out of the cellcentral vacuoles are found in mature plant cells that store water so that the plants do not dieVesicles are of two different types -transport vesicles that take the protein from the rough Endoplasmic Reticulum and transport it to the Golgi Bodiessecretory vesicles that carry the finished proteins to the cell membranesLysosomes are vesicles that are sacs containing digestive enzymes, These are found only in animal cells. Their function is to digest macromolecules and clean up any dead organelles. For cellular digestion the lysosomes fuse with the food vacuole to break down the polymers.
Enzymes are protein materials found in all areas of the body. In the respiratory system, enzymes act as catalyst for the many chemical reactions.
Stomach enzymes would have a considerably lower optimum pH than most other enzymes found in the human body.
Enzymes are an important part of the digestive system, where they chemically digest food into usable nutrients. Enzymes with different functions are found in many other areas of your body.
Lysosomes contain hydrolytic digestion enzymes. Lysosomes are membrane- bounded vesicles produced by the Golgi apparatus. When lysosomes are fused with macromolecules brought into the cell by vesicle formation at the plasma membrane, then the contents are digested by lysosome enzymes into simpler subunits that then enter the cytoplasm.
Enzymes for digesting lipids, or fats, are called lipases. Enzymes for digesting proteins are called proteases. Enzymes for digesting carbohydrates are called amylases. Note that there are many different types of each of the above enzymes.
