Integral proteins are only found on the inner surface of a cell membrane. (T or F) d. Endocytosis is the process that occurs to eject biomacromolecules from the cell. (T or F) e. Pinocytosis uses a signaling molecule from another cell, binding to the cell membrane to bring about changes within the cell proteins. (T or F) Your Answer: a=false b=true c=false d=false e=false a. True b. True c. False- (Peripheral proteins are found on the inner or outer surface of the cell membrane. Integral proteins span the entire length of the membrane.) d.

(1)Lysosomes (2) buildup of toxic lipids inside the cell (biomacromolecules) (3) disability and death In the genetic disease known as Tay-Sachs, one of the normally present digestive enzymes inside lysosomes is lacking. Thus, a toxic lipid in the brain cells cannot be broken down. The resulting buildup of lipids in these cells can cause intellectual disability and death.
