Question
Chapter 5, Problem 6FTB
Summary Introduction
To review:
The given blank space in the statement, “The general process by which fluids or particles are transported into cells is called ______. Does this process require energy? ________. The specific term for engulfing fluid is __________, and the term for engulfing particles is _________. The engulfed substances are taken into the cell in membrane enclosed sacs called _______.”
Introduction:
Transport of molecules across a membrane is one of the most common cellular activities that occur within the body and generally requires energy input. Some processes like diffusion, active transport, endocytosis, and exocytosis are important for maintenance of concentration gradients, acquiring food, and expelling wastes.

Note: lysis is the correct answer but there is more answer on the question.
An artificial cell consisting of an aqueous solution enclosed in a selectively permeable membrane (but with no cell wall) is immersed in a beaker containing an aqueous solution. The outside environment concentration consists of 0.01 M glucose and the inside of the cell has a concentration of 5.0 M glucose. The plasma membrane is permeable to water and monosaccharides, but impermeable to the disaccharides. Complete the following for the image below:
Is the glucose going down or against its concentration gradient? Is the movement of the solute in the cell going out of the cell?
Down...Yes
Down...No

- Organelles and Cystic Fibrosis A plasma membrane transport protein called CFTR moves chloride ions out of cells lining cavities and ducts of the lungs, liver, pancreas, intestines, and reproductive system. Water that follows the ions creates a thin film that allows mucus to slide easily through these structures. People with cystic fibrosis (CF) have too few copies of the CFTR protein in the plasma membranes of their cells. Not enough chloride ions leave the cells, and so not enough water leaves them either. The result is thick, dry mucus that clogs the airways to the lungs and other passages. Symptoms include difficulty breathing and chronic lung infections. In 2000, researchers tracked the cellular location of the CFTR protein as it was being produced in cells from people with CF (Figure 3.13). Figure 3.13 Cellular location of the CFTR protein. Graph compares the amounts of CFTR protein found in endoplasmic reticulum, vesicles traveling from ER to Golgi, and Golgi bodies in CF cells and normal cells. In which organelle is the amount of CFTR protein most similar in both types of cells?arrow_forwardOrganelles and Cystic Fibrosis A plasma membrane transport protein called CFTR moves chloride ions out of cells lining cavities and ducts of the lungs, liver, pancreas, intestines, and reproductive system.
