A-Level Biology Lessons (Full Term)

We’ll break down the light-dependent reactions, looking at how light energy is converted into ATP and NADPH, with a focus on key diagrams and exam-style questions.

We’ll explore the Calvin cycle step by step, then apply it to real exam questions on limiting factors and graph interpretation.

We’ll go through glycolysis and the link reaction in detail, showing how glucose is broken down into useful intermediates and where students often lose marks.

We’ll tackle the Krebs cycle and oxidative phosphorylation, focusing on ATP yield, redox reactions, and common misconceptions.

We’ll study how energy is transferred through ecosystems, looking at efficiency, biomass pyramids, and the key calculations examiners love to test.

We’ll cover how nitrogen and phosphorus are recycled in ecosystems, using simple flow diagrams and exam-style application questions.

We’ll study how blood glucose is controlled, the roles of insulin and glucagon, and how diabetes develops, with lots of data-handling practice.

We’ll unpack how muscles contract using the sliding filament model, with detailed diagrams and practice on linking theory to exam questions.

We’ll examine how the kidney regulates water balance through osmoregulation, linking structure to function and testing common application-style questions.

We’ll learn how to calculate allele frequencies using Hardy–Weinberg, with guided examples and plenty of past-paper style practice.

We’ll explore natural selection and how it leads to speciation, using clear examples and exam-focused application questions.

We’ll study how genes are switched on and off through transcription factors and epigenetic changes, focusing on data interpretation and evaluation questions.
