QUESTION 1 Mark the true statements concerning this image. The best labels left to right are hypotonic solution, isotonic solution, and hypertonic solutions. Image 2 shows cells that are quickly losing fluid and shrinking. The best labels left to right are hypertonic solution, isotonic solution, and hypotonic solutions. Beaker three indicates cells are swollen to the point of bursting. QUESTION 2 Which statements are true of 4? This is a peripheral membrane protein, found on only one side of the membrane. This is a cholesterol molecule embedded in the core of the membrane. This protein is not tagged with a carbohydrate, so it is not a glycoprotein. This protein is a channel for transport. QUESTION 3 ______ are the main fabric of the plasma membrane. Cholesterol Phospholipids Integral proteins Peripheral proteins QUESTION 4 Which of the following is true of osmosis? It is vital to the water balance of all cells. When water cannot pass through a membrane. It is not very important to the life of cells. None of these are true. QUESTION 5 Plasma membranes are selectively permeable, meaning that all substances pass through freely substances can enter, but not exit freely. only water can enter and leave the cell it permits only certain substances to transport across the membrane QUESTION 6 Movement down the concentration gradient means molecules moving from areas of low concentration to high. high concentration to low heat towards water None of these. QUESTION 7 Match these descriptions to the correct transport model. A. simple diffusion B. facilitated diffusion C. active transport D. bulk transport A. movement of molecules across the membrane from higher concentration to low B. movement of solute out of the cell down the gradient using a membrane protein C. movement of molecules that requires ATP D. movement of transport vesicles and their contents QUESTION 8 Choose the one statement true of passive transport. It requires ATP. It is for recycling damaged cells and bacteria. It is only for the movement of water. It moves small, uncharged molecules across the membrane from areas of high concentration to areas of low concentration. QUESTION 9 Choose the list that contains the three types of passive transport: active transport, simple diffusion, facilitated diffusion isotonic, passive diffusion, facilitated diffusion osmosis, simple diffusion, facilitated diffusion None of these lists are correct. QUESTION 10 Specialized cells can identify specific targets for ingestion and engulf proteins, debris, and other cells. What is the term for the cellular ingestion of large particles or cells? exocytosis phagocytosis transcytosis pinocytosis
