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..

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).
Once a macrophage engulfs a bacteria by the process of phagocytosis, the bacteria ends up in a membranous sac called a phagosome. When a phgosome encounters a lysosome inside the cell, the two membranes fuse.This creates a phagolysosome, which is where the bacteria get digested.nce a macrophage engulfs a bacteria by the process of phagocytosis, the bacteria ends up in a membranous sac called a phagosome.
