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. 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).
Cells contain small, membrane-bound sacs that contain a cocktail of  digestive chemicals. These sacs, called lysozymes, are responsible  for the destruction and turnover of â¦ cellular material. lysosome is a sac of digestive enzymes, used to break down  monosaccharaides and disaccharides. Lysosomes are found in animal  cells and are also called suicide sacs. 1 person found this useful. Edit.
