Indicate the type of microscope which would be most suitable for examining the structures described below. Identify each group in the space provided. Lipids, which spontaneously form bilayers to distinguish the inside of a cell from the external environment 8. There are several different phospholipids found in biological membranes. The number of phosphate groups esterified to the glycerol portion of the phospholipid 11.
Biological membranes are capable of repairing small holes or tears that are made in the membrane.
Explain how the properties of the lipids that are found in the cell membrane contribute to this self-sealing property. A kinase that transfers phosphate groups to tyrosine residues on integral membrane proteins 14. Circle all compounds listed below that are capable of passing through a cell membrane by simple diffusion. One of the compounds we worked with in lab, sodium azide, is poisonous. Bind to DNA and cause errors in DNA replication 17.
