T/F: the purpose of cellular respiration is to produce ADP false. purpose is to produce ATP 3. T/F: peripheral proteins are found on the outer surface of a cell true 4. T/F: exocytosis is the process that occurs to bring biomacromolecules inside the cell false. this is endo- cytosis 5. T/F: receptor mediated endocytosis uses a signaling molecule, from another cell, bringing to the cell mem- brane to bring about changes within the cell proteins true 6. T/F: endocytosis is a passive process. it doesn't re- quire cellular energy expenditure false. endocyto- sis is an active process requiring cellular energy 7. discuss Tay Sachs disease. what organelle within the cell is impacted? what are the symptoms of the dis- ease and why do they occur? 1. lysosomes are impacted. 2. the buildup of toxic lipids in- side the cell lead to disability and death. this occurs because one of the normally pre- sent digestive en- zymes inside lyso- somes is lacking so a toxic lipid in the brain cells can't be broken down, resulting in 1 / 6

T/F: integral proteins are only found on the inner sur- face of a cell membrane true 29. T/F: cellular respiration occurs in the mitochondria true 30. list the 3 steps of cellular respiration glycolysis, citric acid cycle, elec- tron transport sys- tem 31. which tissue covers the body surface and lines the cavities of the body epithelium 32. what is anabolism synthesis of com- plex molecules from simpler ones 33. list the 6 levels of organization of the body chemical - cellular - tissue - organ - organ system - or- ganism 34. air and food pass in which of the following--trachea, nasopharynx, oropharynx, alveoli oropharynx 6 / 6
