RNA carries authorisation. Protein metabolism executes the order.

In this episode, Medlock Holmes follows genetic information to its most tangible outcome: proteins that are synthesised, folded, directed, deployed, and — when their work is done — dismantled. Translation is revealed not as a single event, but as the opening act in a carefully supervised l…

DNA may hold the master record, but it rarely speaks directly. In this episode, Medlock Holmes follows information as it leaves the archive — transcribed into RNA, reshaped, edited, and prepared for use.

RNA metabolism reveals a striking principle: information is not simply copied; it is curated. Transcription initiates the process, but splicing, modific…

Organisation alone is not enough. Information must be preserved through time, duplication, and stress. In this episode, Medlock Holmes examines DNA metabolism — the set of processes that ensure the genome is faithfully copied, vigilantly repaired, and resilient in the face of constant threat.

DNA is not a static record. It is actively replicated, continu…

Having traced metabolism and regulation, Medlock Holmes returns to biological information with new eyes. The question is no longer what is written in DNA, but how it is organised — and why that organisation matters.

In this episode, genes are revealed not as isolated instructions, but as elements embedded within chromosomes — structured, folded, constrai…

By now, Medlock Holmes has followed dozens of pathways — branching, converging, competing. In this final episode of Bioenergetics & Metabolism, he steps back to ask the only question that now matters: who decides?

Hormonal regulation is revealed as the quiet authority that integrates metabolism into a coherent, organism-wide response. Insulin, glucagon, …

Breakdown alone cannot sustain life. At some point, what has been dismantled must be rebuilt.

In this episode, Medlock Holmes examines how cells construct complexity from modest precursors. Amino acids, nucleotides, and related molecules are not scavenged whole; they are assembled step by step, with precision and restraint. Each biosynthetic route reflec…

Catabolism answers the question of survival. Biosynthesis answers a different one: what do we do with more than we need?

In this episode, Medlock Holmes follows carbon not as it is burned, but as it is deliberately redirected into long-term form. Lipid biosynthesis is revealed as an act of confidence — a decision that energy is plentiful enough to be sto…

Until now, Medlock Holmes has followed energy as it is transferred, transformed, and conserved within living systems. In this episode, he steps back further still — to examine how energy enters the biological world in the first place.

Photosynthesis is treated here not as a plant-specific curiosity, but as the foundational act upon which nearly all metab…

Episode Description

Every pathway so far has been a preparation. In this episode, Medlock Holmes arrives at the place where all prior decisions are settled — oxidative phosphorylation, the final accounting of cellular energy.

Here, electrons harvested from carbohydrates, fats, and amino acids are passed along an ordered chain, not to create chaos, but to …

Carbohydrates burn cleanly. Fats burn patiently. Proteins, however, leave something behind.

In this episode, Medlock Holmes turns to amino acids as metabolic fuel and discovers that their oxidation presents a unique problem: nitrogen. While carbon skeletons can be redirected into energy pathways, nitrogen cannot simply accumulate. It must be handled, neu…
