Question

llutture of a triglyceride. Compare your structures from part A and part B. Based on the structures, how are triglycerides and phospholipids similar? How are they different? (1 pt) Label each major group on your diagram.(0.5 pts.) For each of the following molecules, describe how it would likely cross the cell membrane to enter into a cell. (2 pts.) 5. a. Does the molecule use active or passive transport (or possibly both)? b. Can the molecule use simple diffusion to cross the cell membrane? c. Does the molecule use facilitated diffusion to cross the cell membrane? d. If the molecule uses a membrane protein to cross the membrane, what type of membrane protein does it use? (Carrier protein, pump, channel protein, and/or aquaporin) Molecule A. Active or passive B.Can it use simpleC.Facilitated diffusion? D.Type of protein Molecule diffusion? used Transport? us H2O H' 02 NO Glucose

Explanation / Answer

1 H2O - passive transport, Facilitated diffusion - YES, aquaporin

2. H+- Active transport, Facilitated diffusion- YES, pump

3. O2 - passive diffusion,   Facilitated diffusion- YES, Carrier proteins

4.Glucose- Active transport, Facilitated diffusion- YES, channel proteins
