Hey! I'm Nicola I am currently studying Medicine at the University of Birmingham. Having always shown great enthusiasm for science, I hope that I would be able to pass this on to other students through my tutorials!
I have spent a lot of time working with younger peers having volunteered at a Cub Scouts group for 5 years. I have also had some tutoring experience in the past both with individual students one-to-one and volunteering in a local primary school.
I believe the sessions must be based 100% on the student. So whatever it is you might be struggling with, I shall aim to explain in as many different ways as possible (i.e. verbally, diagrams, graphs, real life examples....) so that hopefully things start to make sense!
It is important that students understand concepts as you go along but also that they can repeat and apply what they have learnt in the future.
I aim to make sessions as fun and interactive as possible to aid learning and boost enthusiasm for all things science!
I have good experience in applying for medicine as I did it myself only last year! Therefore, I have an insight into what universities are after, how to format your personal statement and can help in preparing for MMI style interviews. The process may seem scary but every medical student goes through the same thing so don't be intimidated!
If you have any questions, send me a 'WebMail' or book a 'Meet the Tutor Session'! through the website. Make sure to let me know what it is you are struggling with and I shall do my very best to help you!

Active transport is the movement of molecules or ions against their concentration gradient, using energy in the form of ATP, across a plasma membrane.
In glucose absorption, there is an initially high concentration of glucose in the lumen of the gut as carbohydrates break down. This means there is a concentration gradient allowing the diffusion of glucose into the cells. Once the glucose is at equilibrium, it then needs to be taken up by active transport:
1) Sodium ions (Na+) are actively pumped out of the cells of the small intestine and into the blood via Sodium/Potassium (Na+/K+) pumps.
2) This creates an Na+ concentration gradient, where there is a higher concentration of Na+ in the lumen of the small intestine than inside the cells.
3) The Na+ then re-enters the cells of the small intestine via diffusion through a sodium-glucose transporter protein (alongside glucose).
4) The glucose concentration inside the cell increases and a concentration gradient is created between the inside of the cells and the blood. This allows glucose to move via facilitated diffusion into the blood.
