Krebs Cycle Infographic with Human Rib Cage Structure

Biological diagram infographic titled "Krebs Cycle". Center the composition around a clean labeled circular cycle diagram with directional arrows showing the sequence of the citric acid cycle in the mitochondrial matrix, designed for a medical professional audience. Use an isometric 3D editorial scientific illustration approach with pastel soft palette, subtle depth, balanced spacing, crisp typography, and sharp readable labels. Show the cycle ring clearly with major intermediates implied visually and emphasize 5 labeled stages/components arranged evenly around the circle, each connected by a thin leader line, each with a short label in English and a one-line function description in English. Include input → output markers for key metabolic entries and products such as acetyl-CoA input, CO2 release, NADH production, FADH2 production, and ATP/GTP generation. Labels to render exactly as: "Citrate Formation" — "Acetyl-CoA combines with oxaloacetate to begin the cycle."; "Oxidative Decarboxylation" — "Carbon is released as CO2 while NADH is produced."; "Succinyl-CoA Step" — "High-energy thioester conversion supports GTP or ATP formation."; "Succinate Oxidation" — "Succinate is oxidized and generates FADH2."; "Oxaloacetate Regeneration" — "Malate is oxidized to restore oxaloacetate and produce NADH." Add small clean callouts for "Acetyl-CoA", "CO2", "NADH", "FADH2", and "ATP/GTP" placed near the relevant arrows. Maintain scientifically accurate biochemical flow and proportions. Background minimal and uncluttered. Include 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.
