Document Summary

Diffuse easily: oxygen, carbon dioxide, alcohols, steroids, non-polar substances. Require facilitated diffusion: sugars (increased intake is facilitated by insulin, increased release is facilitated by glucagon), proteins, ions (na+, k+, ca+, h+) Active transport: transporting substances from an area of low concentration to high concentration (transport against the concentration gradient), requires atp. Microtubules tubulin structure, attach to kinetochores, track for organelles, cilia & flagella. Microfilaments actin structure & support, cytokinesis, microvilli. Intermediate filaments keratin structure & strength.
