5: Membranes (part 1) Quizellenjmchenry2019-09-09T22:39:21-04:00 Please sign up for the course before taking this quiz. When a cell needs a bag to store or transport something, it uses a:1 lysosome phospholipid zipper-lock baggie vesicle What is the electrical charge of a phosphate ion?1 3- 1- 1+ 3+ Can an enzyme do more than one job?1 No Yes The Greek word for “dissolve or break apart” is:1 vacuus lipo lys soma An empty phospholipid sphere is called a:1 membrane lysosome vesicle liposome What geometric shape will phospholipids automatically form when put into a polar substance?1 flat sheet circle sphere long line What important job does the lysosome do?1 Builds cell membranes. Stores fats and protein molecules. Breaks down proteins, starches and fats so their parts can be recycled. Transports things across the cell. REVIEW: Is water polor or non-polar?1 polar neither non-polar REVIEW: What does hydrophilic mean?1 water hating water loving Which part of a phospholipid molecule loves water– the head or the tails?1 head both tails neither What is the inside of a lysosome like?1 basic (alkaline) salty acidic neutral REVIEW: A glycerol hanger with three fatty acids attached is called a:1 triglyderide phospholipid hydrophobic tail saturated fat An acid donates what to its environment?1 electrons hydroxide ions protons How many different types of digestive enzymes might be in a lysosome?1 3 8 50 only one A lipsome that is filled with water or air is called a:1 vacuole vesicle membrane lysosome 4: Lipids (part 2: Phospholipids) 6: Membranes (part 2: Membrane Transport) Back to: 5: Membranes (part 1)
