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.

Carbohydrates are sugars that break down inside the body to create glucose. Glucose is moved around the body in the blood and is the primary source of energy for the brain, muscles, and other essential cells.The healthy body attempts to regulate glucose levels by using a series of hormones â insulin and glucagon, which are produced by the pancreas gland.ecause of their simple molecular structure the body can process these simple sugars quickly â this leads to an energy spike, a sudden rush of energy as sugars are converted to glucose followed by a low once the process is complete and the simple carbohydrates have been used.
