The life Process of a cell

In my report you will learn about the life process of a cell based on the two main functions, metabolism and mitosis. You will learn about the four stages of metabolism: ingestion, digestion, respiration, and excretion, and how the cell completes them. You also will acquire information about the four stages of mitosis: prophase, metaphase, anaphase, and telephase, and how the cell completes them. Mitosis is the process in which cells reproduce. These two processes are interdependent on each other.

The steps of metabolism are the same for any species. First the cell must ingest glucose through active transport. The glucose is ingested through the cell membrane. There are only 2 ATP?s yielded in each glucose. An ATP is an energy enriched molecule. That is not enough energy to completely digest it. It is just enough energy to get it to the mitochondria. The enzymes in the mitochondria respire. Also now it has 34 ATP?s. Then the lysosomes fully digest it. Then the all the waste is excreted by the golgi bodies and vacuoles. The cell has fully metabolized. Now the process starts over.

Mitosis is the process in which a cell divides into two new cells. The four steps of mitosis are prophase, metaphase, anaphase, and telephase. The step where the cell prepares for mitosis is called interphase. During interphase all of the chromosomes duplicate, and then are joined at the centrimere. Now mitosis begins, first in prophase all of the chromosomes then gather in the center of the cell, and the two centrioles go to opposite ends of the cell. Also the nucleic membrane breaks down. Next in metaphase the two centrioles create polymers called spindle fibers, that go across the whole cell. For every chromosome there is a spindle fiber. The chromosomes attach them selves onto the spindle fibers, in the middle, or the equator of the cell. In anaphase the duplicated chromosomes separate from each other, and each chromatid goes to an end of the cell. In the last step of mitosis, telephase the cell membrane breaks, and then closes off, leaving two new daughter cells. The two new daughter cells will go through same process.

Cell metabolism, and cell mitosis are alike in a few ways. Both of the functions are completed in four main steps. A cell must do both of those things, to stay alive. Also, reproduction and metabolism are two of the five qualifications of a living organism (grow/develop, move, reproduce, metabolize, respond to a stimulus). If a cell didn?t metabolize, it could not reproduce. When a cell metabolizes it creates energy. Part of that energy is used for the cell to reproduce. There are some cell parts that are used on both of the cell processes, such as the cell membrane. In metabolism food such as glucose, or lipids are ingested through the cell membrane. During mitosis the cell membrane will stretch, and break apart into two new daughter cells. Cell metabolism and cell mitosis are two complicated processes that work naturally together.

It should be clear to you now the different stages of cell metabolism and cell mitosis. The stages of cell metabolism are ingestion, digestion, respiration, and excretion. The stages of cell mitosis are prophase, metaphase, anaphase, and telephase. More importantly, each stage has a definite and necessary job to create and sustain life. The understanding of the scientific knowledge of these processes enhances the amazement that all life begins and is sustained by cell metabolism, and cell mitosis.
