How it works
AI builds the diagram
MyMap's AI generates a labeled Krebs cycle diagram with intermediates arranged in a circular pathway, annotated with carbon counts, CO2 release, and NADH/FADH2/GTP outputs.
Refine and export
Add enzyme names, label regulation sites, or ask AI to connect the cycle to glycolysis and the electron transport chain. Export as PNG or PDF for class or study.
About the framework
What is a Krebs Cycle Diagram?
A Krebs cycle diagram (also called the citric acid cycle or TCA cycle) is a visual representation of the central metabolic pathway that oxidizes acetyl-CoA to produce energy carriers for the electron transport chain. Discovered by Hans Krebs in 1937, it is the second stage of cellular respiration.
The cycle takes place in the mitochondrial matrix and processes the acetyl groups from carbohydrate, fat, and protein metabolism into CO2 and high-energy electron carriers.
Key components in a Krebs cycle diagram
- Acetyl-CoA entry — the 2-carbon acetyl group combines with oxaloacetate (4C) to form citrate (6C)
- Oxidative decarboxylations — two CO2 molecules are released as the 6C citrate is converted to 4C succinyl-CoA
- Energy carrier production — 3 NADH, 1 FADH2, and 1 GTP are generated per cycle turn
- Intermediate regeneration — oxaloacetate is regenerated to accept the next acetyl-CoA
- Eight intermediates — citrate, isocitrate, alpha-ketoglutarate, succinyl-CoA, succinate, fumarate, malate, oxaloacetate
Krebs cycle diagrams are essential in biochemistry and biology education for understanding cellular energy metabolism, metabolic regulation, and the connections between carbohydrate, lipid, and amino acid metabolism.
MyMap's AI generates accurate, labeled Krebs cycle diagrams from a simple description — ready for study guides, presentations, or classroom use.

Frequently asked questions
Common questions
Is the Krebs cycle diagram maker free?
Yes — you can generate Krebs cycle diagrams for free without signing up. Free accounts include a generous number of AI messages per month. Upgrade to Pro for unlimited diagrams.
Can I customize the diagram after it's generated?
Absolutely. Every intermediate and annotation is editable — add enzyme names, adjust carbon counts, add regulation arrows, or ask AI to include the link to oxidative phosphorylation.
Does it show all eight steps of the cycle?
Yes. The AI can generate all eight reactions from citrate through oxaloacetate, including isocitrate, alpha-ketoglutarate, succinyl-CoA, succinate, fumarate, and malate with accurate carbon counts.
Can I connect it to other metabolic pathways?
Yes. You can ask AI to show how the Krebs cycle connects to glycolysis (via pyruvate decarboxylation), the electron transport chain (via NADH and FADH2), and gluconeogenesis.
What are the energy outputs per cycle turn?
Each turn of the Krebs cycle produces 3 NADH, 1 FADH2, and 1 GTP (equivalent to 1 ATP). Since glucose produces 2 acetyl-CoA, the cycle turns twice per glucose molecule, yielding 6 NADH, 2 FADH2, and 2 GTP total.
