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.

There are three main types of carbohydrates, which are sugars, starches and fibre. Carbohydrates contain about 4 calories per gram. The main function of carbohydrates is to provide your body with fuel and energy that is required to carry out daily activities and exercise. When carbohydrates are in our body, they are being broken down and used as energy. When the body doesn't need to use the carbohydrates for energy, it stores them into the liver and muscles and is called glycogen. When the liver and muscles cells cannot store anymore glycogen, it is turned into fat.
