Unformatted text preview: Active Transport vs. Facilitated Diffusion: Both require help of transport proteins, but in active diffusion the cell must expend energy because substance is moving from low to high concentration (against gradient). In facilitated diffusion the cell expends no energy because substance are moving from high to low concentration (with gradient). Active Transport vs. Group Translocation: Active transport simply moves materials across membrane, while group translocations modifies the chemicals prior to crossing the membrane. Both forms of transport utilize energy. 11. Match the following characteristics of eukaryotic cells with their functions. Pericentriolar Material - Microtubule formation Chloroplasts - Photosynthesis Golgi Complex - Secretion Lysosomes - Digestive enzyme storage Mitochondria - Respiration Peroxisomes Oxidation of fatty acids Rough ER Protein Synthesis...
