So for the new study design, a lot of information has been removed when it comes to AO2 - Detecting & Responding. What are some of the topics that have been removed that don't need focusing on? Can someone please give me a rundown on it? Would be much appreciated and beneficial for everyone. Cheers.
Endocrine system:
All you need to know:
- Different types of hormones (peptide/protein, lipid-based and amino acid derivative).
- Signal transduction
- Signal transduction and the action of hormones at the cellular level (e.g. Instead of looking at insulin acting as a hormone to reduce blood glucose levels, you'd look at insulin as acting on specific target cells, and the response it initiates being an increase in the permeability of the cell membrane to glucose, to increase absorbption of glucose from the blood, and in the long run, lower blood sugar levels during hyperglycaemia).
Nervous System:
All that has been taken out is the generation of action potentials.
