A resistorâcapacitor circuit (RC circuit), or RC filter or RC network, is an electric circuit composed of resistors and capacitors driven by a voltage or current source. A first order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuit.RC circuits can be used to filter a signal by blocking certain frequencies and passing others.s : So at DC (0 Hz), the capacitor voltage is in phase with the signal voltage while the resistor voltage leads it by 90Â°. As frequency increases, the capacitor voltage comes to have a 90Â° lag relative to the signal and the resistor voltage comes to be in-phase with the signal.
Making the world better, one answer at a time. The carbohydrate chains on membrane proteins serve as recognition markers; they aid in cell-to-cell recognition.aking the world better, one answer at a time.

o Starch: alpha linkages, and branched The branching in glycogen allows for quick mobilization of glucose for energy. 11. Animals store energy as either a carbohydrate or a lipid. Why would an animal use both these molecules for energy storage? What structural differences facilitate their different uses? Carbohydrates: short term storage; branched for quick mobilization Lipids: long term storage; They are more reduced than carbohydrates yielding more energy per carbon, and they are hydrophobic, thus stored anhydrously, so there is more carbon per gram of lipids. Thus, they yield more energy/gram than carbohydrates. 12.
