Heart Model Labelled Krebs Cycle Biology Infographic

Biological diagram infographic titled "Krebs Cycle" centered on a clean labeled circular pathway diagram of the citric acid cycle inside a simplified mitochondrion context, designed for university undergraduate learning. Arrange the composition as a circular flow with clear directional arrows, not as body anatomy, with 9 labeled stages/components evenly spaced around the cycle and connected by thin leader lines to the ring. Each label must contain a short heading in English and a one-line function description in English. Include input → output markers for major molecules entering and leaving the cycle. Show biologically accurate sequence and proportions of the cycle intermediates and energy carriers. Labels to render exactly as: "Acetyl-CoA" — "2-carbon input that combines with oxaloacetate to begin the cycle."; "Citrate" — "6-carbon molecule formed by condensation of acetyl-CoA with oxaloacetate."; "Isocitrate" — "Rearranged intermediate that prepares for oxidative decarboxylation."; "alpha-Ketoglutarate" — "5-carbon intermediate formed with release of CO2 and production of NADH."; "Succinyl-CoA" — "High-energy 4-carbon intermediate that drives substrate-level phosphorylation."; "Succinate" — "4-carbon intermediate oxidized to generate FADH2."; "Fumarate" — "Intermediate produced by succinate oxidation before hydration."; "Malate" — "Hydrated intermediate oxidized to regenerate oxaloacetate and NADH."; "Oxaloacetate" — "4-carbon acceptor regenerated at the end of the cycle to continue turnover." Add small flow annotations exactly as: "Input: Acetyl-CoA", "Output: 2 CO2", "3 NADH", "1 FADH2", "1 GTP (or ATP)". Visual style: minimal flat scientific, forest green and earth palette, soft beige background, muted olive, moss, deep green, clay brown, and warm gray accents; calm academic mood; medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All labels sharp, evenly spaced, highly readable, and visually balanced around the circular pathway. Include a subtle mitochondrion outline behind the cycle for context, without distracting from the pathway. No graphic gore, no real patient photos, no watermarks. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no graphic gore, no real patient photos, no watermarks No graphic medical gore, no real patient photographs, no surgical blood. For human anatomy, keep illustrations educationally tasteful. For animal anatomy, no cruelty imagery. Scientifically accurate labeling and proportions.
