Answer 1

Answer 1 :)

The four forms of energy in the human body are as below:-

1. Chemical energy:

This energy produces through the reactions of two or more than two chemicals. Energy always produces in the form of exergonic reactions. For example, ATP hydrolysis yields 30.5 kJ/mol, which is a chemical reaction.

2. Mechanical Energy:

This type of energy produces through the uses of external body parts of the human body. For example, using our hands to pick up something actually produces energy through hand movement.

3. Electrical energy:

This type of energy generally produces through ions movements in the body. We know that our nerves need action potential to generate nerve impulses, which actually produces through the ion gradient from either sides of the neuron.

4. Heat:

This is the energy of temperature, which we can feel through the body heat or temperature. Our body’s temperature maintains body’s inside environment. This heat is very crucial for the immunity of our body too. After death, body gets cool, which is a sign of loss of heat.
