1. Core Concepts

ATP — Adenosine Triphosphate

The primary energy currency of every cell. ATP stores chemical energy in phosphate bonds; cleaving the terminal bond releases ~7.3 kcal/mol and powers muscle contraction, nerve signaling, and protein synthesis. Each ATP molecule cycles approximately 1,000–1,500 times per day.

Oxidative Phosphorylation

A five-complex electron transport chain (Complexes I–V) embedded in the inner mitochondrial membrane. Electrons from nutrient breakdown pass through Complexes I–IV, pumping protons across the membrane. ATP synthase (Complex V) uses this proton gradient as a molecular turbine. Complex IV (cytochrome c oxidase) is notable as a photoacceptor — it absorbs red and near-infrared light, linking photobiomodulation to ATP output.

Mitochondrial Membrane Potential (MMP)

The electrical potential difference across the inner mitochondrial membrane, typically ~150–180 mV (negative inside). MMP drives ATP production. A decline in MMP reduces ATP output and is associated with cellular stress, impaired calcium handling, and reduced resilience to metabolic demands.

AMPK — The Energy Sensor

AMP-activated protein kinase functions as the body's central metabolic switch. When cellular ATP falls and AMP rises, AMPK activates catabolic pathways (fatty acid oxidation, glucose uptake, mitochondrial biogenesis) while suppressing anabolic pathways. Exercise, caloric restriction, and certain compounds are established AMPK activators. A 2024 animal study (Scientific Reports) reported that graphene far-infrared exposure was associated with AMPK pathway activation in mice.

Mitochondrial Biogenesis

The process by which cells increase mitochondrial mass and copy number. Regulated primarily by PGC-1α (peroxisome proliferator-activated receptor gamma coactivator 1-alpha), mitochondrial biogenesis is triggered by exercise, cold exposure, and energy deficit — conditions that signal increased ATP demand. More mitochondria = greater cellular energy capacity.

Reactive Oxygen Species (ROS)

Byproducts of mitochondrial respiration, primarily superoxide (O₂⁻). At moderate levels, ROS serve as signaling molecules. In excess — a condition termed oxidative stress — ROS damage proteins, lipids, and DNA. Mitochondrial dysfunction and excess ROS are often observed together. A 2022 in-vitro study reported a 10.7% decrease in ROS following graphene FIR exposure in a yeast model.
