Lysosomes are involved in the following: a. Na-K-ATPase Protein Pump O b. Phagocytosis O c. Pinocytosis d. Exocytosis Oe. All of the Above

Gap junctions between cells allow direct contact of the cytoplasm between neighboring cells. What kind of cells might you find these in and how do they facilitate the function of these cells?

When the slime mold receives its own autocrine signal of CAMP the response is the activation of transcription of transmembrane adhesion molecules. These adhesion molecules need to be transcribed, translated and shipped to the plasma membrane. This response is an example of O a endocytosis O b. exocytosis Oc. phagocytosis Od. endosomal recycling
