In many ways, '''Metabolosomes''' are an extension of '''[[Cytoplasm]]'''.

Unlike eukaryotes, prokaryotes do not have membrane-bound organelles. In other words, their organelles do not have membranes. Instead, prokaryotes like bacteria construct compartments out of proteins. A metabolosome is an example of such a compartment, officially referred to as a bacterial microcompartment (BMC). BMCs are composed of a polyhedral protein shell around 100-200 nm large that looks similar to a virus capsid. The proteins that make up the shell typically have (semipermeable) pores that allow different compounds (substrates and products) in and out of the organelle. They concentrate enzymes and proteins involved in specific metabolic processes in one spot, ensuring their success. The protein shell also acts as a physical barrier, allowing BMCs to conduct metabolic reactions that create toxic or unstable intermediate compounds.  
Once a cell evolves a '''[[Nucleus]]''', it's advisable to replace '''Metabolosomes''' with their eukaryotic equivalent, '''[[Mitochondrion|Mitochondria]]''', since these are much more efficient.


Metabolosomes are a catabolic type of BMC, and are involved in the degradation of different carbon sources such as glycerol and amino acids. There is no clear evidence that the process of breaking down glucose takes place in metabolosomes, however it is not unreasonable to assume that it could do so.

The actual process of breaking down glucose for energy takes place in several steps in both prokaryotes and eukaryotes. The only difference is where some of the enzymes are located and organized. Below is a summary of the various reactions with the full names of the molecules and the chemical formulas/abbreviations. 
 
 
'''Glycolysis:'''
Glycolysis takes place in several steps, catalyzed by 10 different enzymes with 11 intermediate compounds. The end result is one glucose produces two pyruvate molecules, two ATP molecules and two NADH molecules (which are later converted to 4-5 ATP molecules). Glycolysis occurs in the cytoplasm of both eukaryotes and prokaryotes
 
The net reaction looks like this:
 
''Glucose + 2 ADP + 2 NAD+ + 2 Pi → 2 pyruvate + 2 ATP + 2 NADH + 2 water''

'''Linker reaction:'''
This reaction connects glycolysis to the next major reaction cycle in ATP production: The Krebs cycle, also known as the citric acid cycle.
 
''2 Pyruvate + 2 CoA + 2 NAD+ + 2 Pi → 2 acetyl-CoA + 2 NADH + 2 CO2''
 
Krebs cycle:
''2 acetyl-CoA + 6 NAD+ + 2 FAD + 2 GDP + 2 Pi + 4 H2O → 2 CoA + 6 NADH + 6 FADH2 + 4 H+ + 2 GTP + 4 CO2''
 
Electron transport chain and oxidative phosphorylation:
 
10 NADH + 10 H+ + 2 FADH2 + 2 GTP + 6 O2 -> 25ATP + 3 ATP + 2 ATP
 
Remeber there is also 2 ATP produced by glycolysis. This brings the total amount of ATP produced to 32.


However, the actual maximum amount of ATP possible varies between species and tissues due to differences in the amount of hydrogens pumped across the mitochondrial membrane by the electron transport chain. In other words, the amount of ATP generated per NADH and FADH2 molecule depends on the species. The total amount is commonly stated as being between 36-38 ATP.  
Unlike eukaryotes, prokaryote organelles do not have membranes. Instead, prokaryotes like bacteria construct compartments out of proteins. A '''Metabolosome''' is an example of such a compartment, officially referred to as a Bacterial MicroCompartment (BMC).

Strategy

In many ways, Metabolosomes are an extension of Cytoplasm. A playstyle that works for the starting cell (LUCA) is likely to work for a cell built from Metabolosomes – simply gather Glucose glucose from the environment. The difference is increased efficiency that can support more organelles with wider functions, such as Perforator Pili or Flagella.

However, natural Glucose glucose concentrations in the environment decrease over the course of the game, so it may be advisable to switch to new food sources later on.

Once a cell evolves a Nucleus, it's advisable to replace Metabolosomes with their eukaryotic equivalent, Mitochondria, since these are much more efficient.
