Protein in cell

Protein, what is Protein? Proteins is a complex organic compound containing carbon, hydrogen, oxygen, nitrogen, and contain sulfur and phosphor. Proteins have a main function in structure and cell function all organism and viruses.

Protein in food which consume human will absorb by intestine in the form amino acid. Sometime amino acid which is peptide and small molecule will absorb through the intestinal wall and absorb into the blood vessels. This is what caused allergic reaction in body that arise in people which consume foods that contain protein like a milk, fish, shrimp, egg, etc.

Cytoplasm

Cytoplasm is basically the substance that fills the cell. It is a jelly-like material that is eighty percent water and usually clears in color. It is more like a viscous (thick) gel than a watery substance, but it liquefies when shaken or stirred.

Cytoplasm, which can also be referred to as cytosol, means cell substance. This name is very fitting because cytoplasm is the substance of life that serves as a molecular soup in which all of the cell's organelles are suspended and held together by a fatty membrane. The cytoplasm is found inside the cell membrane and the cytoplasmic organelles.

Bacteria

Bacteria
Bacteria are a large group of prokaryotic organisms, except Archaea. Bacteria have a very small size (microscopic) and have a big role in life on earth. In the classification bacteria classified in the Divisio schizomycetes.

Several groups of bacteria known as causative infection and disease. While other groups could provide enormous benefits to human life, particularly in food, medicine, and industry.

Bacteria have a simple cell structure: without nucleus (main cell), cell skeleton, and another organelle like a mitochondria and chloroplast. This became a basis different between prokaryote cell and eukaryote cell (more complex cell).
