digestion
The Golgi apparatus. It creates lysosomes.Lysosome: Lysosomes contain hydrolytic enzymes necessary for intracellular digestion. They are common in animal cells, but rare in plant cells.
enzymes
The lysosome contains the most enzymes of the cell. This is because the lysosome is the site of cellular digestion.
Cells can digest substances through intracellular digestion, where enzymes break down molecules inside the cell's cytoplasm, or through extracellular digestion, where enzymes are secreted outside the cell to break down larger substances before they are absorbed.
Naturally occurring enzymes are proteins that catalyze biological reactions in living organisms. They are produced by cells to speed up chemical reactions that are essential for life, such as digestion, metabolism, and growth. Examples of naturally occurring enzymes include amylase, which breaks down starch, and catalase, which helps break down hydrogen peroxide into water and oxygen.
These enzymes are anchored into the cells that make up the brush border as integral membrane proteins. These enzymes are found near the transporters that enable absorption of the digested nutrients.
In the process of intracellular digestion, lysosomes are the main organelles. Lysosomes contain enzymes that are made by cells, and their primary function is to digest things.
The function is to complete the digestion of starches, proteins, and fats.
Proteolysis is the breakdown of proteins into their constituent amino acids by enzymes called proteases. This process is important for the regulation of protein activity and turnover in cells.
Food vacuoles are structures that form in other organisms, such as protists, to digest food inside their cells. In humans, digestion mainly occurs in the stomach through the action of enzymes and stomach acid breaking down food. The human digestive system does not form food vacuoles because digestion is extracellular, occurring in the stomach and intestines rather than inside cells.
Enzymes are produced by cells to catalyze and speed up biochemical reactions within the body. They lower the activation energy needed for a reaction to occur, making processes more efficient. Enzymes play a crucial role in various physiological functions such as digestion, metabolism, and DNA replication.
