We are a pair of higher level IBDP biology students just trying to pass our exams. So now we&#39;ve decided to go through the entire syllabus episode by episode and sharing our progress with you. This is not a replacement for actual revision though, please do not rely on us for all of your DP biology knowledge.

Today we&#39;re back to finish the genetics unit, with an explanation of meiosis, inheritance, and the entirety of the higher level content of genetics, which included meiosis, inheritance, and speciation.

Unit 3.3, 3.4, 10 Genes and What They Do With Us (Also Meiosis)

https://s3.us-east-2.amazonaws.com/pod-public-media-files/2022/4/19/19/cc656bce-ab5d-4d4c-b4c0-d23057a83918_episode7.mp3

In this episode we discuss the units about genes, chromosomes, and genetic modification and biotechnology. The latter includes everything from gel electrophoresis, GMO, and cloning.Meiosis and inheritance will be covered along with the higher level content in the next episode.

Unit 3.1, 3.2, 3.5 Genes and What We Can Do With 'Em

In this episode we discuss photosynthesis at higher level depth, so explaining both the light-dependent and light-independent reactions, and how they rely upon one another to ultimately produce energy. In addition Calvin&#39;s lollipop experiment is also discussed.

Unit 8.3 Calvin Cycle and Friend

https://s3.us-east-2.amazonaws.com/pod-public-media-files/2022/4/15/11/2f98566a-06dd-40a2-9cb8-d3dcb98dba57_episode_5.mp3

Today we are discussing cell respiration, so covering glycolysis, the link reaction, the krebs cycle, and oxidative phosphorylation via chemiosmosis, also known as the electron transport chain.

Unit 8.2 Krebs Cycle and Friends
