A Little Bit About Lizzie:
I am a Biomedical Science student studying at Newcastle University. I recieved grade A's in Biology, Chemistry and Maths at A-level, and have always had a real passion for science!
I am patient and have a very positive attitude. I’ve gained experience from tutoring many younger students throughout my A-level studies, and have learnt how to work with children and young adults after teaching ballet for many years.
You will have control of the content that we cover in our sessions, I will prioritise any problem areas you may have, and I will make sure we find the best learning techniques to suit you as an individual.
To start with, I will spend our time explaining the basic concepts, and then with the help of mind maps, analogies and acronyms, we will build up your knowledge!
I will teach you ways of memorizing the content as well as just learning it, so that by the time your exams come along you will feel comfortable with the content and confident explaining the concepts.
Learning how to ace your exam technique is a massive part of the revision process! I will show you how to ensure you gain all the marks available for the questions you answer. Going through past papers and preparing model answers will make you feel comfortable with the exam layout. Exam period can seem daunting, and my aim is to ensure that you feel confident and well prepared!
Most importantly though, I want out sessions to be productive and enjoyable, you’ll be surprised at what can be achieved in 55 minutes!
What’s Next Then?
Please send me a ‘WebMail’ or book a ‘Meet the Tutor Session’ if you are interested or have any questions you’d like to ask me!
I look forward to meeting you!

When there is an excess of glucose in the blood (as there would be after eating a meal), the increase in blood glucose concentration is detected by the beta cells of the islets of Langerhans in the pancreas. They respond by increasing the secretions of the hormone insulin.
Insulin will increase the rate of glucose uptake by activating enzymes that convert glucose to glycogen, so blood glucose levels will lower and return to normal. This process is called glycogenesis.
Low blood glucose levels are detected by alpha cells of the islets of Langerhans of the pancreas. These cells will respond by increasing the secretions of glucagon into the blood.
Glucagon is a hormone that will activate enzymes in the liver, these enzymes will convert glycogen to glucose in a process called glycogenolysis. Glucagon will also stimulate formation of new glucose molecules in a process called gluconeogenesis. As more glucose is synthesised and released into the blood, the blood glucose levels will return to normal.
This system is controlled by negative feedback, once blood glucose concentrations have returned back to the normal level, the receptors involved will detect this and stop secreting excessive amounts of hormone (insulin or glucagon).
This process provides homeostasis; the maintainance of a constant internal environment and independance of fluctuating external conditions. Homeostasis is achieved by negative feedback.see more
