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