coincise notes on hormones, andrenal glands, pancreas (structure & colour under microscope), insulin and glucagon mode of action, diabetes type 1 and type 2 potential treatments

coincise notes on aerobic and anaerobic respiration, summarising processes through diagrams from online sites (save my exams) to visualise better the cycles and stages. bullet points to add extra information and summarise stages of oxidative phosphorylation in short

Module 5 chapter 15 communication and Homeostasis. This set of notes include notes from lecturer, powerpoints, textbook and complies with the specification. I have designed these notes to not only help with the understanding of the topic but also on how to answer exam style questions, so not only revising the topic but also having a fair understanding on how to tackle an exam style question.
