Cell Processes and Body Organisation Nucleus The nucleus is the largest‚ most prominent organelle‚ usually spherical and roughly about 10mm in diameter. Every eukaryote cell‚ with the exception of red blood cells due to their very specific function‚ has a nucleus. The nucleus’ function is to store DNA‚ it does so in two ways: One is tightly packed and this is called heterochromatin‚ this isn’t read. And the other is loosely packed‚ named euchromatin. Euchromatin is the actively read material

Question: Describe five different organelles and their functions. Explain the similarity and differences between eukaryotic cells and prokaryotic. All eukaryotic cells‚ whether from animals‚ plants‚ protists‚ and fungi‚ are fundamentally similar to one another but different from prokaryotic cell. A eukaryotic cell contains various other organelles‚ which perform specific functions in the cell. These organelles can be organized into few basic functional groups such as genetic control‚ distribution

Insulin pumps send insulin through a small catheter continuously in small doses. This is places in a subcutaneous area and stays there for 2 or 3 days. The insulin pump is usually placed in the abdomen area or the buttocks. When it’s time for meals or snacks the patient can push a button which sends a bolus of insulin. This method is for patients who wants to have good control of the glucose levels and have a flexible lifestyle. Oral hypoglycemic medication is for patients who have type 2 diabetes

Structure of Insulin Focus concepts The three dimensional structure of insulin is examined and sequences of various animal insulins are compared. Prerequisites • • • Amino acid structure Protein architecture Basic immunology Background Diabetics lack the protein insulin‚ which is produced by the pancreatic β-cells of the islets of Langerhans. Insulin stimulates uptake of glucose from the blood into the tissues. Diabetes is treated by replacing the missing insulin. Human insulin is produced

up of cells. All living things are composed of basic building blocks of life called cells. Cells are special; they vary in shape and size. Cells can be round‚ square‚ spindle-shaped and star-like (Cells‚ 2017). Cells carry out many roles inside your body. For instance‚ the macrophage is large white blood cells that is part of our immune system and is responsible for locating and eating microscopic foreign bodies. Epithelial cells protect the surface of our bodies as part of the skin. Cells in the

Each cell can be regarded as a metabolic compartment‚ as separate place where the chemical processes of that cell occur‚ the cell is made up of different organelles each specifically designed to carry out their function‚ and this is known as a cells ultrastrucure. All cells have a cell surface membrane; these are made up of phospholipids and make up a bilayer. A phospholipid has a hydrophilic head and a hydrophobic tail which is made up of 2 fatty acid chains; these are arranged is two layers with

ANIMAL CELL MODEL ORGANELLE FUNCTIONS Cell membrane: Separating the interior of the cell from the outside environment‚ the cell wall is selectively permeable‚ only letting certain things through. It is involved in a variety of cellular processes‚ such as cell adhesion and cell signalling. Cytoplasm: The fluid that fills the cell‚ cytoplasm uses its dissolved enzymes to break down larger molecules. The products can then be used by the organelles that are suspended in the cytoplasm. Cytoskeleton:
