Step by step
Solved in 2 steps
- 1.) Select/highlight the statements that are TRUE regarding simple diffusion. a) It is a form of passive transport. b) It is how glucose travels across the cell membrane C) It is used to transport larger molecules such as polysaccharides. d) It is the method used to transport small, nonpolar molecules. 2.) What is the name of the process occurring in the diagram below and additionally, what is the name given to the condition/outcome/state created on the right side of the diagram below?For this practice problem, would the answer be c)NaCl? My reasoning behind this is because molecules under 100 Da can use simple diffusion, while nonpolar molecules and larger molecules like benzene can use channels via facilitated diffusion. However, NaCl dissociates into ions and cannot readily use diffusion?Membranes that contain a significant proportion of cis unsaturated fatty acids are more fluid than similar membraneswith higher levels of saturated fatty acids. Explain.
