The Pathways

Subject: Biochemistry · Metabolism 

Short Description: Metabolism's greatest hits, narrated by a glucose molecule on a nocturnal journey through the cell — in a smooth, atmospheric male-vocal R&B style. Glycolysis, the TCA cycle, oxidative phosphorylation, and gluconeogenesis, built around the rate-limiting enzymes and their regulators (the MCAT's favorite biochem traps). PFK-1, isocitrate dehydrogenase, and the energy logic that controls them all.

What's Included:

• 1 high-quality WAV audio file
• 1 cinematic lyric video (HD)
• Sound: Smooth Male-Vocal R&B / Dark Pop
• Glycolysis, TCA cycle, oxidative phosphorylation, and gluconeogenesis
• The rate-limiting enzymes and their activators/inhibitors
• The complete metabolic pipeline from glucose to ATP, plus the energy-charge logic

Lyrics:

I'm glucose.
Six carbons, ready to burn.
Take me through the pathways, baby
watch the energy turn.
Glycolysis - cytoplasm, no oxygen required.
Split me into pyruvate, two of them, ATP acquired.
Net two ATP, two NADH when it's done.
The small return up front, but the journey's just begun.
The gatekeeper is PFK-one, tracking my days.
Rate-limiting, committed step, controlling the whole phase.
ATP and citrate slow it, high energy says no.
But AMP, it speeds me up. Low fuel says let's go.
From the cytoplasm to the mitochondria I ride.
Pyruvate at the doorway, PDH is my guide.
Strips a carbon, makes NADH, yields acetyl-CoA
the link, the bridge, the key that opens up the way.
These are the pathways — watch the energy flow.
Glycolysis, TCA, electron transport, go.
PFK-one, isocitrate - the gates that set the rate.
NADH carries the current to the chain that makes me great.
Glucose to pyruvate to the cycle in the night.
Follow me through the pathways — chasing ATP light.
The TCA — the Krebs, the citric acid round.
Acetyl-CoA comes in, and the carbons break down.
Isocitrate dehydrogenase, the rate-limiting gate.
ADP speeds it up, but ATP and NADH make it wait.
Every turn strips electrons, NADH, FADH2.
Carriers full of current, and they know just what to do.
They hand it to the chain, oxidative phosphorylation.
Electron transport, proton pump, the cell's power station.
Complex one through four, the electrons cascade down.
Cytochrome c oxidase, but cyanide shuts it down.
The gradient is building, protons charging up the gate.
ATP synthase is spinning, making energy, my fate.
These are the pathways, watch the energy flow.
Glycolysis, TCA, electron transport, go.
PFK-one, isocitrate, the gates that set the rate.
NADH carries the current to the chain that makes me great.
Glucose to pyruvate to the cycle in the night.
Follow me through the pathways, chasing ATP light.
But flip it all around when the fuel is running low.
Gluconeogenesis - make glucose, watch it grow.
Fructose-1,6-bisphosphatase - the gate for the reverse.
Citrate and ATP say go, but AMP it makes it worse.
High energy builds me up, low energy breaks me down.
The cell is always reading. Should it store or burn it now?
Same logic, opposite doors, the body keeps the score.
ATP is the currency that every pathway's working for.
These are the pathways - watch the energy flow.
Glycolysis, TCA, electron transport, go.
PFK-one, isocitrate, the gates that set the rate.
NADH carries the current to the chain that makes me great.
Glucose to pyruvate to the cycle in the night.
Follow me through the pathways, chasing ATP light.
I'm glucose.
Six carbons, and now I'm spent.
Turned to energy, baby
every carbon's gone and went.
The pathways. The pathways.
