Question

Purpose of the glycocalyx: a. Protection b. Regulation of molecules c. Structure d. ion exchange. Carbohydrate layer on the plasma membrane includes all of the following except a. Adhesion b. Recognition c. Gives a cell its distinctive characteristics d. no one of these answers are correct Bacteriorhodopsin: a. Act as a membrane transport protein b. Act as a membrane channel protein c. Act as a membrane protein receptor d. Act as a membrane gated channel protein. Which structures add to the fluidity of the plasma membrane: a. Carbohydrates b. ATP c. glycocalyx d. cell cortex e. none of these are correct. Which enzyme ensures there is an equal distribution of newly synthesized phospholipids across the membrane? a. Flippase b. Spectrin c. Scarmblases d. transferase True and False Spectrin is a protein found in all eukaryotic cell that provide support to the plasma membrane. Transmembrane proteins allow large particles to pass through the membrane. Certain prokaryotes and eukaryotes adapt to changing environments by changing the unsaturated hydrocarborate tails of the plasma membrane Animals, yeast, bacteria, and viruses contain membrane organelles Animals, yeast, bacteria contain a cell membrane Reduction is gaining of H+ and oxidation is gaining of H+ Formation of macromolecules is an energetically favorable reaction that is coupled with formation of an energetically favorable reaction The breakdown of macromolecules is a spontaneous reaction Vmax is used to indicate if the substrate is binding very tightly to the enzyme. A high Vmax indicates weak binding and a low Vmax value indicates tight bonding Activated carriers are large molecules that that contain one energy-rich covalent bonds

Explanation / Answer

36) Glycocalyx is a glycoprotein protective layer seen in certain vscteria. The glycocalyx layer surrounds the cell membrane of bacteria. This glycocalyx layer helps bacteria against engulfment by phagocytes. It also enables bacteria to get adhered to certain substances. Therefore, the answer for this question is option a (protection).
