Hi, my name is Matt and I'm a medical student at St George's University of London.
I achieved A*A*A* at A level in Biology, Chemistry and Maths and 8 A*'s at GCSE.
After having recently gone through the exam process, now more than ever it is becoming aparent that the marriage of sound exam technique and knowledge of the course is key to success in examinations. I have worked with people of all abilities and have moulded my teaching skills to suit their needs and don't shy away from ensuring the basics are perfect before moving onto more advanced areas as I know too well that the basics can get overlooked in a time pressure classroom environment.
I am also avaible to assit in medical school applications and all that goes with it be it personal statments, UKCAT, BMAT and interview technique to get you your place in medical school first time round.
Please feel free to drop me a message or arrange a free meet the tutor session.
See you soon!

Many grana, large surface area for photosynthetic pigments, electron carriers and ATP synthase enzymes.
Photosynthetic pigments are arranged into structures called photosystems, allows maximum absorption of light energy.
Chloroplasts can make some of the proteins they need for photosynthesis, using genetic info from the chloroplast DNA and using the 70S ribosomes to make the proteins.
Grana surrounded by the stroma so the products from the light dependent reaction (which occur across the thylakoid membrane which make up the grana) can readily pass into the stroma for the light independent reaction.
Chlorophyll is a mixture of pigments containing a long hydrocarbon chain and a porphyrin group with a magnesium atom in the centre. Chlorophyll a (and b) are found at the centre of the photosystems and are known as the primary pigment reaction centre. Each absorb red light at a slightly different wavelength.
Accessory pigments do not contain a porphyrin group and are not directly involved in the light dependent reaction. They absorb light wavelengths that are not well absorbed by chlorophylls and pass the light energy to chlorophyll a at the base of the photosystem. Carotenoids reflect yellow and orange light and absorb blue light. Carotene and xanthophyll are the main carotenoid pigments.
They also contain lipid droplets which can be used in making the phospholipid bilayer of the inner and outer membrane of the chloroplast.see more
