PROTEINS 100 pts Membranes are made of mostly proteins and A: Water B: Glucose C: Phospholipids D: Golgi C. PHOSPHOLIPID 100 The phospholipid bilayer that surrounds the cell is known as a DRAW for (200 pts) A: Non permeable layer B: Fluid Mosaic Model C: Permeable layer D: Main protection for cell B. Fluid Mosaic Model 300 pts Which of the following is NOT a function of a membrane protein? Helps a cell A: communicate with others ( gives it a tag) B: then transfers the C: Helps catalyze D: reactions ( enzymes) Accepts signal and message to the cell Regulates genetic information D. Regulate Genetic Information 300 pts Which of the following sets have opposite effects? A: Diffusion, passive transport Active transport, and C: the actin of the sodium pump B: Endocytosis, exocytosis Facilitated diffusion, D: movement through a protein channel C. Endocytosis, Exocytosis 200 pts Molecules will always move from a High to Low concentration until they reach A: Turgor Pressure B: Equilibrium C: Cytosis D: Plasmolysis B. Equilibrium 200 pts Diffusion is an example of A: Phagocytosis B: Active transport C: Exocytosis D: Passive transport D. Passive Transport 300 pts If an egg cell is put in a solution with mostly solutes , the solution environment is A: Hypertonic B: Isotonic C: Hypotonic D: Osmosis Hypertonic 300 pts A plant is put in a hypotonic solution. This increases the A: Active transport B: Plasmolysis C: Turgor Pressure D: Exocytosis C. Turgor Pressure
