In every cell there are three main parts: the nucleus, the cytoplasm, and the cell membrane. The nucleus is a spherical body usually located near the center of the cell that contains the genetic code of the cell and its purpose is to serve as the control center. Cytoplasm is the fluid medium for the many molecules and organelles the cell has. The cell membrane is the outer layer that separates the cell from its environment and controls what enters and leaves the cell. The nucleus is the control center of the cell. The master program that controls the life and the physical characteristics can be found in the cell. In the master program is DNA, which is short for deoxyribonucleic acid. The nucleotides in one DNA strand have a specific job with the other surrounding nucleotides in the other DNA strand. The main function of the nucleus is to store DNA and to take information from the DNA. A human cell has about four to six feet of DNA. …show more content…
Its role is to act as a medium in the cell. The cytoplasm has a large amount of organelles also known as little organs. Large protein molecules called enzymes are found in both the cytoplasm and in the organelles. Enzymes carry out many chemical reactions in order to create energy, they also transform raw materials into useful substances, or break down old proteins to be recycled. The cytosol in a cell does more than just suspend the organelles. It uses its dissolved enzymes in order to break down all of the larger molecules. The products can then be used by the organelles of the cell. Glucose exists in the cytosol but the mitochondria can 't use any of it for fuel. The cytosol has enzymes that break glucose down into pyruvate molecules that are then sent to the
