Body Diagram Back View Krebs Cycle Pathway Infographic

Biological diagram infographic titled "Krebs Cycle Pathway" centered on a clean labeled pathway-flow diagram of the citric acid cycle, rendered as a circular metabolic pathway with clear directional arrows plus input → output markers for entry and energy products, for a medical professional audience. Show an editorial-grade scientific plate composition with the cycle ring central, elegant spacing, sharp readable typography, and 7 labeled components arranged around the diagram with thin leader lines. Each label must include a short heading in English and a one-line function description in English. Use biologically accurate biochemical naming and proportions. Visual style: vintage 1900s scientific plate. Color palette: natural anatomy tones, muted sepia, parchment cream, olive, umber, desaturated teal, subtle rust accents. Mood: scholarly, archival, precise, refined. Include a small legend for arrows and energy carriers if needed. Mark these 7 labels exactly with quoted on-image text: 1. "Citrate" — "Formed when acetyl-CoA condenses with oxaloacetate to begin the cycle." 2. "Isocitrate" — "Rearranged intermediate that prepares for the first oxidative decarboxylation." 3. "Alpha-Ketoglutarate" — "Produced with NADH release and carbon loss as CO2." 4. "Succinyl-CoA" — "High-energy intermediate that drives substrate-level phosphorylation." 5. "Succinate" — "Converted while transferring electrons to FAD to form FADH2." 6. "Malate" — "Oxidized to regenerate oxaloacetate and produce NADH." 7. "Oxaloacetate" — "Accepts acetyl-CoA to restart the citric acid cycle." Add pathway input and output markers in English: "Input: Acetyl-CoA", "Output: 2 CO2", "Output: 3 NADH", "Output: 1 FADH2", "Output: 1 GTP (or ATP)". Emphasize mitochondrial matrix context subtly in the background without clutter. medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. 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.
