The skin is the body's largest organ. It's made up of many different types of cells. Oils, produced by the sebaceous glands, pre
vent the skin from drying and splitting. The pigment melanin, produced by melanocytes in the epidermis, protects the skin from the harmful effects of ultraviolet radiation. Sweat, released through ducts to the skin surface, helps to cool the body. The types of cells that produce these compounds have different numbers of specific organelles, depending on their function. Melanocytes use many enzymes to produce melanin. Based on their function, you would expect melanocytes in the skin to have a higher than usual number of
Based on their function, you would expect melanocytes in the skin to have a higher than usual number of ribosomes.
Ribosomes are cell structures that functions as the site of biological protein synthesis. Ribosomes are present in all living cells where they produce proteins required for many cellular functions. Ribosomes join amino acids together in the order specified by messenger RNA molecules. Ribosomes are made up of two parts which are; the large subunits (which connect amino acids to create a polypeptide chain) and the small ribosomal subunits (which read the RNA).
Yes they can because the catalyst does not take part in the chemical reaction and remains unchanged after the reaction has ended. Biological catalysts are known to be recycled by the bodies in which they work.
