Homework Answers
,Na, exists in cardiac muscle cells whose effect is to depolarize the membrane so that the resting potential, V m, is positive to the potassium equilibrium potential, E K. In ventricular cells, we can increase the permeability of an axonal membrane to sodium ions, the equilibrium potential for sodium in the cell will increase, because the influx of sodium depolarizes the neuron.
2) change in extracellular sodium will alter the sodium equilibrium potential and hence the membrane potential of all cells

Please help me with several of these questions, thank you very much. 1. During the propagation of an action potential along the axon of a neuron, what is happening at the leading edge (the front) of the region of depolarization as it moves down the axon? a. Ligand-gated Na+channels are opening. b. Voltage-gated Na+channels are opening. c. Ligand-gated K+channels are opening. d. Voltage-gated Na+channels have become inactive and refractory. e. Voltage-gated Na+channels are closing. 2. During transcellular transport of glucose...

What is typically the role of an inhibitory synapse? to open Na+ channels in the post-synaptic membrane to depolarize the post-synaptic membrane to generate an EPSP to hyperpolarize the post-synaptic membrane If a post-synaptic nerve cell receives a large number of EPSPs from synapses on different dendrites, what is the most likely result? A hyperpolarization Mechanical summation Spatial summation An IPSP Why might natural selection have favored cephalization? It allows animals to better detect stimuli behind them, if they are...

Roles of the Na+/ K+ pump 1. Maintain the Nat/K+ concentration gradicnt across the plasma membrane. (That's obvious) 2. It plays a role in maintaining the resting membrane potential. Why? 3. The steep electrochemical gradient of Na+ is used in "coupled active transport" (coupled pumps). If the Nat/K+ pump stops, then these Na+ coupled transport mechanisms will also eventually stop. Explain The apical surface of the epithelial cells that line the lumen of the gut contains a symport that used...

4. Development of organelles Aa Aa 3 Modern eukaryotic cells are very complex and have many features that allow them to function efficiently. These complexities took a very, very long time to evolve and likely progressed as a series of small improvements that were naturally selected. For example, modern eukaryotic cells have internal membranes surrounding their organelles and the nucleus. This arrangement likely arose when the cellular membranes of some ancient bacterial cells accidentally folded to become internal membranes. Which...
