Introduction Tafazzin, encoded by the nuclear gene TAZ is primarily found in the inner mitochondrial membrane, where it plays an important role in cardiolipin (CL) remodeling (Xu et al. 2006). Tafazzin shares amino acid sequence homology to acyl transferases (Vreken et al. 2000). TAZ is located on chromosome Xq28 and comprises 11 exons and 2 alternative translation initiation sites (Johnston et al. 1997). Among four major transcripts: TAZ-FL (full-length), TAZ-Δ5 (lacking exon 5), TAZ- Δ7…

1. (a) Diffusion refers to the movement of molecules from an area of high concentration to an area of low concentration of those molecules. The factors that influence the rate of diffusion across a membrane are: ~ the extent of the concentration gradient – the greater the difference in concentration on either side of the membrane, the faster the rate of diffusion ~ the mass of molecules diffusing – the heavier they are, the slower they will diffuse across the membrane ~ the distance travelled –…

Cancer is a disease that have been infecting people for centuries. It is also the leading cause of disease worldwide. According to the cancer research group in the uk, in the year 2012 there was an estimate of 14.1 million new cases of cancer. This was split 53% in males and 47% in females. Several cancer types exists and I will be focusing on breast cancer. In the years 2013 the American Cancer Society stated that there was 64,640 new in Situ cases and 232,340 new invasive cases. In situ cancer…

Concentration Gradient effects the rate of Osmosis in Artificial Cells. During our biology lab we learned all about cells, and to further our understanding we even conducted an experiment with an artificial cell. To start the lesson, we learned the difference between diffusion and osmosis, how concentration gradients affect both. Also how the cell membrane works, how tonicity affects plant and animal cells differently, how dialysis tubing works, and how it acts like a living cell. By the end of…

Cooking oils are a fairly important ingredient in every kitchen and are used on almost daily basis. All oils do the same job, they are used in various cooking techniques and dishes, but each one of them have different quality markings which are usually given by the FDA or other food testing organisations. Cooking oils come in a wide variety such as palm oil, sunflower and olive oil. Oils are a necessity for a proper diet but only if consumed under control, as per the FDA a full grow should only…

nucleus and therefore all its genetic information is stored in the cytoplasm of the cell. The bacterial cell envelope protects the cell and consists of a cell membrane(s) and a cell wall. The cell membrane surrounds the cytoplasm is composed a phospholipid bilayer which contains hydrophobic membrane proteins (Slonczewski & Foster, 2015). The cell wall that protects the cell…

commonly referred to a fats. They are used for energy and cell structure. There are multiple types of fats, including saturated fats, unsaturated fats, polyunsaturated fats, and phospholipids. Saturated fats, unsaturated fats, and polyunsaturated fats are used for energy because they store large amounts of it. Phospholipids are used for cell structure. Proteins are the final organic compound. They are made up of amino acids that are chained together. Since there are 20 types of amino acids,…

Morrison (2012) explains that nurses have specialised knowledge to gather comprehensive physical assessments and differential diagnoses. Evidence-based practice utilises the best available evidence and clinician expertise to formulise an evidence based decision (Bickley, 2013). This essay will analyse the diagnostic reasoning behind decisions made in the diagnosis of a client. A brief diagnosis and pathophysiology will be explained, followed by the client’s health history, physical examination…

Osteoporosis is a disease linked to weak bones. It effects around 54 million Americans daily (Learn What Osteoporosis Is and What It’s Caused By, 2017). While anyone may be diagnosed with osteoporosis it is more common in the elderly and women. Osteoporosis involves the bones of the body. Bone has two types of tissue, cortical bone and trabecular bone. Osteoporosis typically affects the trabecular bone mostly because it regenerates more quickly than cortical bone, and osteoporosis interrupts…

Evan Meyer Professor Nolan Biology 104:14 1/19/18 Journey Through a Cell Eukaryotic cells have one thing in common that is a nucleus and organelles enclosed by a plasma membrane. The cells are found in a variety of living things including animals, plants, fungi, and protozoa. Inside the cells, the nucleus and the organelles perform distinct functions to keep the cell alive as well as meeting its purpose. One cannot imagine how the complex unit of life can feed, replicate, and perform its…
