thank you for the videos they are so useful! although I have a question, in the ib biology oxford book or guide I cant find anything related to primary, secondary, tertiary, and quaternary structure of protein except in topic 7. so does that mean I learn it only for hl because they are included in this video as well for topic 2

Hi, im a student from spain. Your lessons are amazing and they have helped me a lot. Would it be possible for you to make videos of topic 7, because it is the most difficult one for me and you would help me and my friendsa lot?

2:11 As of 2024 at least, the model is known by the IB as the "hand in glove" model. Please not that and don't write the "lock and key model" in the test.
