Degree: Medicine (Bachelors) - Manchester University
I am a final year medical student at Manchester. I have a keen interest in the sciences (especially in Biology) and I also have an extra undergraduate degree (a BSc in Pathology). I hope that my interest in science will give you a similar experience to mine! I also studied History at A-Level and have always had a big interest in it.
I am very easy going and friendly. My degree involves a lot of teaching, whether it is formally at the university or hospital, or casually with friends and those in younger years.
The pace of my sessions will be entirely up to you. I believe that an understanding of the basics is very important, so I am always happy to go through anything at your pace. If you are more advanced, I would also be delighted to go into more complex material. Most importantly, I'll try to make everything I teach fun and easy to understand.
At the start of each lesson we can recap what we discussed in the previous session and then move on to new topics. Near the end we can discuss some exam questions and work on exam technique.
Medical School Applications
I've been through exactly what you're going through and have helped many people improve their personal statements and CVs. I can always help if you need some advice on making sure you get through the ordeal that medical schools put students under.

The control of blood glucose levels is an example of homeostasis. The human body requires glucose for normal respiration of cells, but the blood levels is in a narrow range.
Insulin and glucagon are hormones released from the pancreas into the blood stream. They are called endocrine hormones, because they are in the blood stream (endocrine).
How Insulin Controls Blood Glucose
Insulin is secreted from the islet cells in the pancreas - in beta cells. HIGH blood glucose stimulates the release of insulin. There is a low level of insulin secreted by the pancreas, but in high glucose levels, more insulin is released into the blood stream. LOW blood glucose results in less secretion of insulin.
In HIGH blood glucose, insulin in the blood stream causes glucose to enter cells resulting in a net reduction in blood glucose - into the normal range.
In LOW blood glucose, more glucagon is released.
The Effect of Glucagon On Blood Glucose
Glucagon is also released by the pancreas, but it acts on liver cells to release glucose contained in glycogen molecules - this is called glycogenolysis (the breakdown of glycogen into glucose).
Glucagon can also stimualte the liver to produce glucose out of other nutrients in the body, like proteins.
If glucose levels are too low then glucagon is released, which results in an increase in blood glucose back to the normal range.see more
Mitochondria are organelles which provide the energy used up by the cell in respiration, through producing molecules called ATP. Some cells have loads of mitochondria, and other cells have very little. For example, muscle cells, which require a lot of energy to do work, have loads of mitochondria whereas neurons have very few.
Structure of Mitochondria
The mitochondria are perfectly shaped to maximise energy production. They have a normal outer membrane which holds all of the contents of the organelle, and an inner membrane which folds over many times to increase surface area. These are called cristae. The fluid in the middle of the mitochondria is called the matrix.
The increased surface area of the inner membrane allows a lot of chemical reactions to happen at once.
How Do Mitochondria Produce Energy?
The matrix is filled with water and proteins (enzymes). These enzymes take organic molecules produced in the breakdown of food (glucose), such as pyruvate and Acetyl CoA and digest them chemically.
Proteins in the inner membrane and enzymes in the citric acid cycle releases water (H2O) and carbon dioxide (CO2) from the breakdown of oxygen (O2) and glucose (C6H12O6).see more
