• AP Biology Reading Guide Julia Keller 12d Fred and Theresa Holtzclaw Chapter 48: Neurons, Synapses, Signaling 1. What is a neuron? Neurons are the nerve cells that transfer information within the body. Communication by neurons consists of long-distance electrical signals and short-distance chemical signals. 2. •Membrane-lined channels called plasmodesmata (PD) connect the cytoplasts of adjacent plant cells across the cell wall, permitting intercellular movement of small molecules, proteins, and RNA. Recent genetic screens for mutants with altered PD transport identified genes suggesting that chloroplasts play crucial roles in coordinating PD transport. •Protein scaffolds are members of the signaling cascade downstream of cell surface receptors. Scaffold proteins help relay the message between the cell membrane and nucleus faster. They do this by serving as a docking site for multiple protein partners in the cascade so they can be near each other.

  • Transport Without Energy. Passive transport occurs when substances cross the plasma membrane without any input of energy from the cell. No energy is needed because the substances are moving from an area where they have a higher concentration to an area where they have a lower concentration. •Justify your answer. The dots, because they are small and can fit though the gaps, and because they are shown as equally distributed on both sides of the membrane Model 2 – The Selectively Permeable Cell Membrane 7. What two major types of biological molecules compose the majority of the cell membrane in Model 2? Phospholipids and proteins 8.
