Questions: 5 | Attempts: 9132 | Last updated: Mar 22, 2023

Sample Question
If blood glucose levels fall below normal levels (for instance, during the post-absorptive or fasting state, when nutrients from a recently digested meal are no longer circulating in the blood, or during starvation), insulin secretion is inhibited and, at the same time, the alpha cells of the pancreas respond by secreting glucagon, a hormone that has several important effects: (1) it accelerates the breakdown of glycogen to glucose in liver and skeletal muscle cells; (2) it increases the breakdown of fats to fatty acids and glycerol in adipose tissue and, consequently, the release of these substances into the blood (which cells can thus use for energy); and (3) it stimulates liver cells to increase glucose synthesis (from glycerol absorbed from the blood) and glucose release into the blood. These effects collectively cause an increase in blood glucose levels back to normal levels.

Sample Question
Sequential excitatory postsynaptic potentials (EPSPs) from a given presynaptic terminal will be most effective at bringing a postsynaptic neuron to threshold when:

Inhibitory inputs are present on the soma

EPSPs are arriving very close together in time

EPSPs are arriving from presynaptic cells that form synapses at a great distance from the axon hillox

Individual excitatory inputs have a low frequency of activity, enabling the membrane to recover from inactivation between EPSPs
