13A – Cells and Movement of Materials P1: Describe the microstructure of a typical animal cell and the main function of the cells components The microstructure of a typical animal cell is made up of various components, all of which play a vital role within the body. Each component has its own specific role that it performs in order for the cell to function and maintains the cell membrane. The main components of the cell include the cell membrane, cytoplasm, the nucleus, nucleolus, nuclear

Enzymes are natural catalysts - substances that speed up a rate of reaction without being used up. They are also proteins that are molded into various shapes that allow substrate molecules to fit inside them. The region where the substrate molecules insert themselves is called the active site. Without enzymes, biological reactions would take excessive time to take place to keep you alive. They are also significant as they aid cells to connect with one another allowing cells to maintain growth, life

Hookworm Introduction Hookworm infection is caused by the blood-feeding nematode parasites of the species Ancylostomaduodenale and Necatoramericanus. Together, the hookworms infect an estimated 576-740 million individuals today of which 80 million are severely infected. The morbidity associated with severe infection includes intestinal blood loss, anemia, and protein malnutrition. The burden of infection is concentrated mostly among the world’s poorest who live on less than $2 a day. A particularly

placement art student, I thank my younger self for discovering photography. With photography, I continue to be a creative and curious artist. My sanity is always questioned when I state that I love molecular biology. But it is true. Learning about macromolecules and ATP is something that I absolutely love to do. While my teachers lecture about oxidative phosphorylation, I watched in fascination, awed at the notion that I now knew how muscles worked. The intricacy and specific role of each enzyme, amino

Nucleus- This organelle is the control center of a Eukaryotic cells. The Nucleus is surrounded by a nuclear envelope composed of two membranes. The nucleus also include nuclear pores that allows a paced stream of proteins, RNA, and other molecules to move into and out of the nucleus to the rest of the cell. Inside the Nuclear envelope, there is a layer of chromatin that consist of DNA bounded with protein; as chromatin condenses, it forms chromosomes that is used to pass hereditary information.

Gluten Free Eating Is Not a Fad – Position Paper Celiac disease (CD) and Non-Celiac Gluten Sensitivity (NCGS) is on the rise. Although general consensus states that the diseases’ incidence varies greatly, research conducted in the last 30-40 years contradicts those claims. Yes, the proliferation can be partially credited to increased efficiency in diagnostic techniques and the “mainstream” status of the diseases, but the spread of affliction in not only the US and Europe, but to geographic areas
