The mutation causing equine periodic paralysis is due to a mutation that causes __ in the channel. slower than normal inactivation O faster than normal inactivation O faster than normal activation O slower than normal activation O inability to inactivate (what type of Voltage sensors in the Nav channels are thought to be a run of amino acids) O positive O negative neutral o What is the consequence of increased blood potassium to the action potential? Increasing extracellular K+ causes...
1. What channels or carriers are NOT found at the axon to the axon terminal? Select one: a. Na+ leaky channels b. Cl- gated channels c. Na+ gated channels d. Na+-K+ ATPase e. None of the above 2. What is TRUE about action potential in the neuron? There may be more than one answer. Select one or more: a. At resting membrane potential (-70mV), the inactivation gate of the Na+ channel is closed while the activation gate is opened. b....
A 35 year old female presents with a history of several episodes, each separated by several months, in which she experiences brief periods of physical weakness, clumsiness of the legs and hands, visual disturbances, and mood swings. Her weakness is most prominent in the lower extremities. CT scans show evidence of multiple lesions in the white matter of the brain and spinal cord. During her last episode, there were increasing neurological deficits due to an increasing number of disseminated lesions....
During the aerobic metabolism of glucose, glucose is ____________. Reduced to form water Oxidized to form water Reduced to form CO2 Oxidized to form CO2 Which of the following describes the equation: FAD + XH2 à FADH2 + X. FAD is reduced to FADH2 It is a coupled reduction – oxidation reaction XH2 is oxidized to X All of the above Which of the following is FALSE about glycolysis? The initial steps of glycolysis requires energy derived from the splitting...
