Raw Materials. Saxophones are primarily made from brass. Brass is a composite alloy made up of metals including copper, tin, nickel, and zinc. The most common type used for instruments is yellow brass which contains 70% copper and 30% zinc. Other types include gold brass and silver brass which have different ratios.
3. Cristae contain enzymes important to ATP production; cristae also increase the surface area for ATP production. e. Lysosomes are membrane-enclosed sacs that contain hydrolytic enzymes, which are important in intracellular digestion, the recycling of a cellâs organic materials and programmed cell death (apoptosis).Lysosomes carry out intracellular digestion in a variety of ways.. Cristae contain enzymes important to ATP production; cristae also increase the surface area for ATP production. e.

Golgi Apparatus. A major organelle in most eukaryotic cells is the structure of membrane-bound sacs called the Golgi apparatus (or Golgi body, Golgi complex, dictyosome). It acts to process and package the macromolecules such as proteins and lipids that are synthesized by the cell.It has been likened to the cell's post office. major organelle in most eukaryotic cells is the structure of membrane-bound sacs called the Golgi apparatus (or Golgi body, Golgi complex, dictyosome).
