Clean scientific illustration, 16:9, pure white background. A semi-transparent human heart on the left in soft pastel blue and teal gradients with subtle depth and 3D shading. Inside the heart, clearly visible enlarged mitochondria arranged in a structured network showing dynamic fusion and fission—some mitochondria splitting into smaller units, others merging into elongated chains. Slightly more detailed cellular texture but still minimal and easy to understand. Mitochondria glow in pastel teal, aqua, sky blue, mint green, and light cyan with soft internal lighting. Gentle flowing energy lines and particle-like bioelectric signals connect mitochondria, showing active cellular metabolism and cardiac health. Modern biomedical 3D infographic style, slightly more detailed and dimensional, smooth lighting, crisp edges, elegant composition. Large empty white space on the right for title text. No labels, no text, no arrows, no clutter, no watermark, high resolution. Mehr sehen
