Which part of a phospholipid molecule loves water– the head or the tails?1 tails head both neither REVIEW: A glycerol hanger with three fatty acids attached is called a:1 phospholipid saturated fat triglyderide hydrophobic tail The Greek word for “dissolve or break apart” is:1 soma lipo vacuus lys Can an enzyme do more than one job?1 No Yes REVIEW: Is water polor or non-polar?1 non-polar polar neither A lipsome that is filled with water or air is called a:1 vesicle membrane vacuole lysosome How many different types of digestive enzymes might be in a lysosome?1 8 only one 50 3 What is the electrical charge of a phosphate ion?1 1- 3+ 3- 1+ 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. An empty phospholipid sphere is called a:1 membrane vesicle liposome lysosome When a cell needs a bag to store or transport something, it uses a:1 zipper-lock baggie phospholipid vesicle lysosome REVIEW: What does hydrophilic mean?1 water hating water loving What is the inside of a lysosome like?1 salty basic (alkaline) neutral acidic 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 flat sheet sphere long line circle 4: Lipids (part 2: Phospholipids) 6: Membranes (part 2: Membrane Transport) Back to: 5: Membranes (part 1)
