1. Battery is a source of energy for a circuit, whereas capacitor is a passive element, which draws energy from the circuit, store and release it. 2. Usually battery is a DC component, whereas capacitor is mostly used for AC applications.It is used to block DC components in circuits. 3. Battery provides a relatively constant voltage when discharging, whereas discharging voltage gets rapidly decreased for capacitors.he battery cells create a voltage difference between the terminals of each cell and hence to its combination in battery. When an external electrical circuit is connected to the battery, then the battery drives electrons through the circuit and electrical work is done.

For example, enzymes are a type of protein that reduces the total amount of energy needed for a chemical reaction to take place.
what is the Purpose of Protein  Protein is necessary for the building and repair of body tissues.   It produces enzymes, hormones, and other substances the body uses.  â¦  It regulates body processes, such as water balancing, transporting nutrients, and making muscles contract.
