Welcome to your CIE AS Cell membranes and transport A special type of diffusion involving water molecules only. Active transport Bulk transport Osmosis Facilitated diffusionSecretory vescicles from the golgi body carry the enzyes to the cell surface and release their contents. This is an example of: Osmosis Pinocytosis Exocytosis PhagocytosisWhere are the GLUT proteins found in cells? Nucleus Plasma membrane Mitochondria CytoplasmWhat is the role of short carbohydrate chains attached to glycoproteins and glycolipids? They serve as a barrier to certain molecules restricting their movement. Serves no purpose They act as receptor molecules They increase the fluidity of the membrane.Select the incorrect statement regarding channel proteins. They allow charged substances, usually ions, to diffuse through the membrane. Most channel proteins are 'non-gated'. Channel proteins have a fixed shape. Channel proteins are water filled pores.Which of the following organelles would display a trilaminar appearance at very high magnifications? Cell surface membrane Cilia Golgi complex MitochondriaWhich process does the plant cells use to get their cell wall building materials to the outside of the cell surface membrane? Diffusion Endocytosis Exocytosis OsmosisSinger and Nicolson's hypothesis for membrane structure. Fluid mosaic model Cell theory Interpolation theory Double helix modelWhich of the following is responsible for the 'mosaic' nature of the cell surface membrane? Phospholipids Proteins Carbohydrates CholesterolConversion of the original signal to a message that is then transmitted is called: Transduction Response Effector StimulusTime is Up!
