The Greek word for “dissolve or break apart” is:1 soma vacuus lipo lys REVIEW: Is water polor or non-polar?1 polar non-polar neither A lipsome that is filled with water or air is called a:1 vesicle lysosome membrane vacuole An empty phospholipid sphere is called a:1 vesicle liposome lysosome membrane What important job does the lysosome do?1 Stores fats and protein molecules. Breaks down proteins, starches and fats so their parts can be recycled. Builds cell membranes. Transports things across the cell. Which part of a phospholipid molecule loves water– the head or the tails?1 neither tails both head When a cell needs a bag to store or transport something, it uses a:1 zipper-lock baggie vesicle lysosome phospholipid Can an enzyme do more than one job?1 Yes No What is the inside of a lysosome like?1 salty neutral acidic basic (alkaline) An acid donates what to its environment?1 protons hydroxide ions electrons What geometric shape will phospholipids automatically form when put into a polar substance?1 sphere long line circle flat sheet REVIEW: A glycerol hanger with three fatty acids attached is called a:1 hydrophobic tail phospholipid triglyderide saturated fat What is the electrical charge of a phosphate ion?1 1- 1+ 3+ 3- How many different types of digestive enzymes might be in a lysosome?1 3 only one 8 50 REVIEW: What does hydrophilic mean?1 water loving water hating 4: Lipids (part 2: Phospholipids) 6: Membranes (part 2: Membrane Transport) Back to: 5: Membranes (part 1)
