BRS4(FM1) - Cellular Bioenergetics
1. Definition
Functional control of ATP production via mitochondrial respiration, ETC efficiency, NAD⁺-linked redox metabolism, and high-demand energy support.
2. Intervention Breakdown
Food-State Leaning
3. Functional Role
↑ ATP availability; ↑ cellular energy output
4. Mechanistic Basis (Implementation of PMs)
Integrated control of ATP production through electron transport, NAD⁺-linked redox metabolism, and rapid phosphocreatine buffering.
PM1 governs Electron Transport Chain Function. PM4 governs NAD⁺ Metabolism. PM6 governs Creatine / Phosphocreatine Buffer.
Together, these PMs operationalise BRS4(FM1) as coordinated cellular bioenergetics.
At the integrated FM level, realised energy output depends not only on fuel supply, but also on whether respiratory cofactors, redox-carrier availability, and rapid buffering reserve are sufficient to keep ATP delivery matched to demand [1][2][3].
5. Underlying Mechanisms and Requirements
5.1 Cofactors and Substrates
| PM | Cofactors | KC substrates |
|---|---|---|
| BRS4(PM1) | CoQ10, iron, riboflavin, niacin | glucose, fatty acids, amino acids (KC1); B vitamins, CoQ10-supportive foods, iron, magnesium (KC2) |
| BRS4(PM4) | B3 | B vitamins, CoQ10-supportive foods, iron, magnesium (KC2) |
| BRS4(PM6) | creatine | glucose, fatty acids, amino acids (KC1) |
5.2 PMs (Primary Mechanisms)
- BRS4(PM1) - Electron Transport Chain Function
- BRS4(PM4) - NAD⁺ Metabolism
- BRS4(PM6) - Creatine / Phosphocreatine Buffer
5.3 KCs (Key Constraints)
5.4 Cross-BRS Links
6. Dietary Levers
Diet
- CoQ10 and respiratory cofactors ← oily fish, meat, dairy, whole grains
- Niacin-supportive foods ← poultry, fish, peanuts, mushrooms
- Creatine ← meat, fish
7. Lifestyle Levers
Lifestyle
- Stable meal structure helps match substrate delivery to daily energetic demand.
- Recovery and sleep quality influence realised energy availability even when dietary support is adequate.
