Even though the name protozoa means first animal, the larger protist group contains some organisms that appear plant like because they A. Have roots that anchor them in one place and cannot move to feed. B. Contain chlorophyll. C. Produce their own food using sunlight to carry out photosynthesis. D. Live in the soil while using nutrients like nitrogen and phosphorus to grow. A protozoan is a single cell. So, what makes a protozoan any different from any of the...

6) In unstimulated muscle cells, the glucose transporter Glute is present in the membrane of endosomes. Upon stimulation of these cells with insulin, the endosomes fuse with the plasma membrane, thereby depositing Glut4 in the plasma membrane, where it serves to transport glucose into the cells. In order for insulin to elicit this change in Glute localization, insulin must bind to its receptor, present in the plasma membrane of some cells. To determine if a stem cell line can be...

Cell Membranes and Dielectrics Many cells in the body have a cell membrane whose inner and outer surfaces carry opposite charges, just like the plates of a parallel-plate capacitor. Suppose a typical cell membrane has a thickness of 8.2×10−9 m , and its inner and outer surfaces carry charge densities of -5.3×10−4 C/m2 and +5.3×10−4 C/m2 , respectively. In addition, assume that the material in the cell membrane has a dielectric constant of 5.5. Part A . Find the direction...

27. Integrins are single-pass integral membrane proteins in the plasma membrane of animal cells and are involved in the interaction of the cell with the surrounding extracellular matrix. Which of the following descriptions do you think matches the transmembrane part of an integrin molecule? A. It forms a B barrel. B. It is an a helix that is bent in the middle. C. It is about 10 amino acids long, with every other amino acid side chain being hydrophobic. D....
