- Liver cells are packed with glucose. If the concentration of glucose in a liver cell is higher than in the surrounding fluid, what mechanism could the cell use to import even more glucose? Why would only this mode of transport work?Which is an example of passive transport? a) A membrane protein uses a hydrogen ion concentration gradient to transport sucrose against its concentration gradient and into a cell b) An ion channel permits sodium ions to diffuse through a cell membrane c) A pump uses ATP as an energy source to transport hydrogen ions out of a cell d) A cell takes in particles by pinocytosis e) The sodium potassium pump transports ions from one side of the membrane to the other, against a concentration gradientWhere does the cell get energy for active transport processes?
- In the process of exocytosis, vesicles coming from the inside of the cell fuse with the plasma membrane which travels across the membrane to be released outside the cell. This type of transport usually applies to enzymes and hormones. Can you cite an Texample in plants where this form of transport is beneficial? How about in animals?A cell relies heavy on energy dependent activities,how does it meet its requirement under different conditions?______ transport uses cellular energy to move materials from an area of lower concentration to an area of higher concentration. The "energy currency" of the cell,which can be used for this type of transport is ________.
- If your cell can use passive transport without having to use energy, why would a cell invest ATP to move particles using active transport? Provide a specific example.Plants use the proton electrochemical gradient across the vacuole membrane to power the accumulation of salts and sugars in the organelle. This accumulation creates hypertonic conditions in the vacuole. Why does this not result in the plant cell swelling and bursting?What is exocytosis? A. The process by which a cell engulfs a large particle or another cell, eating it B. The process by which a cell expels the contents of an internal vesicle to the extracellular fluid C.
