determine if a GTPase switch protein has been turned on/off and if it was fast or...
GTPase switch proteins cycle from on to off states depending upon which nucleotide version is bound. Signal-induced receptor activation leads to the conversion of the GTPase switch protein from an to an state mediated by a factor. is released and replaced by resulting in a conformational change that allows the protein to activate downstream effector proteins. The intrinsic GTPase activity causes of GTP to GDP and the conversion back to the off state.
The Ras protein functions as a molecular switch that is turned on by a GEF that causes it to bind GTP. A GAP then turns the switch off by inducing Ras to hydrolyze its bound GTP to GDP much more rapidly than in the absence of GAP. (1) In a cell line that lacks Ras-specific GAP, what abnormalities in Ras activity, if any, would you expect to find in the absence of extracellular signals? (2) And in their presence (presence...
8. Repeat exercise 5 for timer off delay (TOF). S goes off 4 seconds after R. T goes off 6 seconds after R. U goes off 2.5 seconds after S. 9. E and F are turned on by a switch. When the switch is turned off, E goes off immediately F remains of for another 7 seconds and then goes off. (TOF) 8. Repeat exercise 5 for timer off delay (TOF). S goes off 4 seconds after R. T goes...

3 The switch in the figure on the left has been in position "A since the war of Ba. Then it was thrown into position to Determine the voltatge across the capacitor as shown fort and calculate its values att4s.
Large capacitors can hold a potentially dangerous charge long after a circuit has been turned off, so it is important to make sure they are discharged before you touch them. Suppose a 120 μF capacitor from a camera flash unit retains a voltage of 210 V when an unwary student removes it from the camera. If the student accidentally touches the two terminals with his hands, and if the resistance of his body between his hands is 1.8 kΩ, for...
Problem : The switch has been in position A for a long time. Att 0 the switch is moved to B. Determine v(t) for t > 0 and calculate its value at t = 2s and t = 6s. 24 V 5 kQ 0.5 mF 30 V
Large capacitors can hold a potentially dangerous charge long after a circuit has been turned off, so it is important to make sure they are discharged before you touch them. Suppose a 120 μFcapacitor from a camera flash unit retains a voltage of 180V when an unwary student removes it from the camera. If the student accidentally touches the two terminals with his hands, and if the resistance of his body between his hands is 1.8 kΩ, for how long...
