Cells are not the structure of protein lipids and other molecules. Rather all cells are
comprised of well-defined structure or component each specialization in particular function of
the cell (Derocles et al. 2016). Many biochemical processes take place in an intercellular
membrane system creates a compartment for the successfully performing these processes
(Matsumura et al. 2017). This paper will illustrate compartmentalization for energy, molecules
for the synthesis of new cells and chemicals for secretion in the following paragraphs.
There are three main compartmentalization observed human cells. These compartments
include mitochondria, nucleus, and lysosomes.
Most eukaryotic cells contain many mitochondria, which occupies up to 25 percent of the
cytoplasm. Mitochondria considered as the powerhouse since it is the main site for ATP
production during the aerobic metabolism. Mitochondria contain inner and outer membrane
separated by inter-membrane space (Damasceno et al. 2016). An outer membrane composed of
protein-based pores that allow the ions and molecules size of the small protein. Inner membrane
contains protein involves in electron transport and ATP synthesis (Lemaître et al. 2015). This
membrane surrounds the mitochondrial matrix where the TCA cycle produces electron that
travels from one complex to next in membrane. At the end of this the electron transport chain,
oxygen accepts the final electron and simultaneously transport chain produce ATP (Lemaître et
al. 2015).
The nucleus is the most prominent organelles as compared to the other cell organelles,
which account for approximately 10% of the cell weight (Lemaître et al. 2015). It consists of the
nuclear membrane, nucleolus, nucleus pores, and chromosomes. Nuclear membrane double-
