Molecules move randomly due to Brownian motion, which increases with temperature. The size of the molecule affects how quickly it can diffuse through the cytoplasm. Try adjusting the temperature to see how it affects molecular movement!
Average Speed: 0 μm/s
Temperature Effect: At 50°C, diffusion is 1.0x baseline
For a deeper understanding of diffusion principles in cellular environments, check out "Chapter 3: Molecular Movement in Cells" in my upcoming book "The Physics of Biology".
