The purpose of cellular respiration is to produce ADP. (T or F) b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or F) d. Receptor-mediated endocytosis uses a signaling molecule from another cell, binding to the cell membrane to bring about changes within the cell proteins. (T or F) e. Endocytosis is a passive process. It does not require cellular energy expenditure.(T or F) 2. True or False? a. The purpose of cellular respiration is to produce ADP. (T or F) b.
