Answer:
E1: Pyruvate dehydrogenase, TPP, oxidative decarboxylation reaction
E2: Dihydrolipoyl transacetylase, Lipoamide and Co-enzyme A, transacetylation reaction.
E3: Dihydrolipoyl dehydrogenase, FAD and NAD+, oxidation reaction
Explanation:
Pyruvate dehydrogenase is a multi-enzyme complex with 5 co-enzymes and 3 apo-enzymes:
Pyruvate dehydrogenase (E1) , which uses thiamine pyrophosphate (TPP) as as co-enzymes to catalyze oxidative decarboxylation of pyruvate to hydroxyethyl-TPP.
Dihydrolipoyl transacetylase (E2): which uses lipoamide and coenzyme A as co-enzymes to catalyse the transacetylation from TPP to Lipoamide to form acetyl lipoamide.
Dihydrolipoyl dehydrogenase (E3) which uses FAD and NAD+ as co-enzymes to catalyze the oxidation of lipoamide

Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.
