Krebs Cycle Diagram Generator

A Krebs cycle diagram shows how acetyl-CoA is oxidized in the mitochondrial matrix to release energy. A citric acid cycle diagram traces the eight enzyme steps from citrate back to oxaloacetate, marking where carbon dioxide, NADH, FADH2, and GTP are produced. SciFig's krebs cycle diagram generator can label every intermediate or leave the figure blank for practice.

The eight steps convert citrate into isocitrate, α-ketoglutarate, succinyl-CoA, succinate, fumarate, malate, and finally oxaloacetate. Along the way the cycle releases two molecules of carbon dioxide and captures energy as three NADH, one FADH2, and one GTP per turn. A labeled krebs cycle diagram places each intermediate around the circular pathway with its enzyme and output.

The Krebs cycle takes place in the mitochondrial matrix, the fluid space inside the inner mitochondrial membrane. A TCA cycle diagram shows the eight reactions arranged in a circle within the matrix, following pyruvate oxidation and preceding the electron transport chain. This location lets the NADH and FADH2 it produces feed directly into oxidative phosphorylation.

Describe the intermediates and outputs you want and SciFig generates the figure for you. A fully labeled krebs cycle diagram includes acetyl-CoA entering, all eight intermediates, the enzymes, and the CO2, NADH, FADH2, and GTP outputs at each step. SciFig's krebs cycle diagram generator produces labeled or blank versions from the same scientifically accurate base.

Each turn of the cycle produces three NADH, one FADH2, one GTP, and two molecules of carbon dioxide. Because two acetyl-CoA enter per glucose, one glucose yields six NADH, two FADH2, and two GTP across two turns. A citric acid cycle diagram marks exactly which step releases each product.

The Krebs cycle is the second stage of cellular respiration, following glycolysis and pyruvate oxidation. It feeds the electron carriers NADH and FADH2 into the electron transport chain, where most ATP is made. A TCA cycle diagram is often paired with the wider respiration overview to show this hand-off.
