Y12 AQA - Weekly group Masterclasses from 1st of October 2024 Tuesdays at 5.15pm

If you are studying AQA A level Biology, you will benefit from joining my Y12 group Masterclasses, which start on Tuesday the 1st of October at 5.15pm

There is a different topic each week.

We cover the required theory, linking this to examples of AQA past-paper exam questions so students can see how to correctly apply their knowledge to gain full credit.

The classes are popular and interactive.

“ I find the A level Biology group tutoring sessions extremely beneficial and effective to consolidating my understanding on topics. The focus the sessions have on understanding biological concepts and how to correctly answer past paper questions has really helped me. Through actively attending the group tutoring sessions my Biology grades are quickly improving from Cs to As. I would recommend the A level Biology group tutoring sessions to any student needing that extra push and guidance (like myself) to achieve the best grade possible in A level Biology.”

The class is only for AQA Y12 students - this focus means I can give advice specific to how AQA word their exam questions and their requirements.

Classes run on every week on Zoom, last an hour, and cost £45.

You are welcome to attend as a paid trial, if you wish to continue then you are committing to attend regularly.

You can save your seat by making an online booking

Carbohydrates, lipids and Food tests - Resources to Test your understanding

Powerpoints, videos and animations, a self marking quiz on lipids and carbohydrates.

Some tips

  • Number the carbons and understand when and how a 1,4 glycosidic bond forms.

  • Why it matters that you can form a 6,1 bond in order to branch a polysaccharide.

  • Why does it matter that polysaccharides are insoluble and mono and di-saccharides are soluble.

  • What is the consequence of Beta glucose forming cellulose

  • Which molecules have a 5 carbon sugar in mammals ?

  • Can you explain why fatty acids are non-polar and what is the consequence for the formation of cell membranes

Respiration - Test your understanding, tips, resources and a quiz

Oxygen is the final electron acceptor. It oxidises the final carrier in the ETC on the inner mitochondrial membrane and is reduced to water.

Hydrogen ions flow from the inter membrane space into the matrix via ATP synthase, this electrochemical gradient phosphorylates ADP.

Hydrogen ions are pumped from the matrix into the inter membrane space, using the energy from the electrons flowing along the ETC. The electrons come from the oxidation of food, transferred by coenzymes NAD and FAD.

Glycolysis occurs in the cytoplasm. Link and Krebs in the matrix. Link and Krebs produce carbon dioxide by the removal of a carboxyl group.

Fermentation is just glycolysis with a different way of regenerating NAD (from NADH) by the reduction of pyruvate (or ethanal).

Substrate level phosphorylation is the direct addition of phosphate to ADP, occurs in glycolysis (4 ATP) and Krebs (once per turn), chemiosmosis is H ions flowing through ATP synthase.

Cristae give a larger surface area for oxidative phosphorylation
