BPHY102 course work 1. Last submitting date : 18.05.2021 Q1. An average cell is about 20 um across, while the axon of a neuron extending from the spinal cord to the toes is about 1 meter long. A glucose molecule has a radius of 0.5 nm, and a medium-sized protein has a radius of about 5 nm. Use equation by Einstein (1905) and Smoluchowski (1906), Brownian motion of spherical molecules, as it relates the time At it would take a molecule of radius r to diffuse distance x. (This process takes place in body!). Answer should have step by step solutions with units!!! a) How long would it take a glucose molecule to diffuse 20 um average cell? b) How long would it take a glucose molecule to diffuse 1 meter long neuron extending from the spinal cord to the toes? c) How long would it take a medium-sized protein to diffuse 20 µm average cell? d) How long would it take a medium-sized protein to diffuse 1 meter long neuron extending from the spinal cord to the toes?
