When i saw that Cells was the first topic on the Biochemistry syllabus..i immediately thought, oh no, Cells has come back to haunt me from form 3 straight to A levels.
However, it was pretty much the same topics as A levels, just more in depth, with a few new interesting concepts. One which i found to be most interesting was Apoptosis.
Makes you think if structures so small mimic human actions or if us humans show similar characteristics as the basic unit that supports all life. As much as i would like to go on and on about apoptosis, i’d prefer to stick to the biochem syllabus, which brings us to the Endosymbiotic Theroy.
Wait!…its actually not as complicated as it sounds, dont let the ‘big words’ fool you. The meaning is in the name itself Endo- in Symbio- Living together. Endosymbiotic theory basically states that eukaryotes originated as symbioses between separate single-celled organisms. There is overwhelming evidence in both the chloroplasts and mitochondria to prove this theory. the chloroplasts and mitochondria were once free living prokaryotic cells that were engulfed by eukaryotic cells, now living in a symbiotic relationship.
If your still confused after that explaination:
I also found a very cute video explaning this theory as a love story!
Thats all for now folks! Hope this helped you in more than one way.
