Biology IB Chapter 1.5

Production of Carbon Compounds such as sugars and amino acids

Miller- Urey experiment

•  
• Assembly into Polymers

Deep sea vents have a lot of energy.

 

3.Formation of membranes

If phospholipids and other amphipathic carbon compounds were the first to emerge, they would naturally turn into a bilayer.

 

4.Development of Inheritance

RNA could have been used at first.

Helps explain the evolution of eukaryotic cells

Mitochondria were once free living prokaryotes that had developed the process of aerobic cell respiration

Larger prokaryotes that could only respire anaerobically took them in through endocytosis but did not digest them.

Same goes for chloroplasts but this time for photosynthesis instead of aerobic respiration

- They both reproduce through binary fission

- They both have circular rings of DNA

- They both have 70s ribosomes

- Chloroplasts and mitochondria are double membrane bc of the engulfing process

- They are the same size

- Chloroplasts and mitochondria can divide independently
