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.

Carbohydrate metabolism denotes the various biochemical processes responsible for the formation, breakdown and interconversion of carbohydrates in living organisms. The most important carbohydrate is glucose, a simple sugar (monosaccharide) that is metabolized by nearly all known organisms.lant components are consumed by animals and fungi, and used as fuel for cellular respiration. Oxidation of one gram of carbohydrate yields approximately 4 kcal of energy, while the oxidation of one gram of lipids yields about 9 kcal.
