Cell biology
1. A cell is eukaryotic because
Is generally larger and much more sophisticated than prokaryotic cells due to the presence of a complex series of membranes that divide a typical eukaryotic cell into compartment.
Eukaryotic cell has an organized nucleus with a nuclear envelop.
Has membrane bound organelles
Contain linear DNA molecule that are larger than the (circular) DNA molecules in prokaryotic cells and, in association with proteins, form structures called chromosomes.
2. Insulin, a peptide hormone, which is released into the blood by the pancreatic beta cell when the blood sugar level is too high (hyperglycaemia) in a regulated secretion pathway to maintain normal blood sugar level (Normoglycaemia), and its synthesis …show more content…
The SER plays an important role in the carbohydrate metabolism, synthesis of fats and phospholipids and in the detoxification drugs. The RER is very important for protein processing and is called rough because it contain ribosomes in its membrane (refer figure1).
The double membranes of rough ER form sacs called cisternae. Insulin molecules are synthesized and collected in the cisternal lumen. When enough insulin have been synthesized, they collect and are pinched off in vesicles. The vesicles often move to the Golgi apparatus for additional insulin packaging and distribution.
Mitochondria They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae (figure 2). The fluid contained in the mitochondria is called the matrix.
They are powerhouse of the cell, which supply energy in the form of ATP during cellular respiration for the whole process of insulin synthesis and secretion to take …show more content…

Plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments. The vesicles containing the insulin move to the plasma membrane, where they either fused immediately with the membrane and release their content to the exterior (as shown in the figure 4) or they are stored near the membrane until a signal such as a neurotransmitter or hormone causes them to fuse with the membrane and release the enclosed content .A process by which a cell transports secretory products through the cytoplasm to the plasma membrane is known as exocytosis.
3. cell cycle
Cell division is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
The first three steps where the cell grows, matures, and carries out its life function are collectively called interphase, followed by mitosis, and
