When a cell needs a bag to store or transport something, it uses a:1 lysosome zipper-lock baggie vesicle phospholipid 3. REVIEW: A glycerol hanger with three fatty acids attached is called a:1 saturated fat hydrophobic tail triglyderide phospholipid 4. What geometric shape will phospholipids automatically form when put into a polar substance?1 long line sphere circle flat sheet 5. REVIEW: Is water polar or non-polar?1 polar neither non-polar 6. REVIEW: What does hydrophilic mean?1 water loving water hating 7. An acid donates what to its environment?1 hydroxide ions protons electrons 8. How many different types of digestive enzymes might be in a lysosome?1 3 50 8 only one 9. The Greek word for “dissolve or break apart” is:1 vacuus lys lipo soma 10. An empty phospholipid sphere is called a:1 vesicle lysosome membrane liposome 11. As a general rule, can an enzyme do more than one job?1 Yes No 12.
