Explain first and second laws of thermodynamics.

The first and second laws of thermodynamics are fundamental principles that govern energy transformations in biological systems, including membrane biology and bioenergetics. These laws not only help explain the flow of energy within cells but also provide insight into how cellular processes are regulated.

First Law of Thermodynamics (Law of Energy Conservation):

The first law of thermodynamics states that energy cannot be created or destroyed in an isolated system; rather, it can only be converted from one form to another. This is also known as the principle of conservation of energy. In biological systems, energy is constantly being converted from one form to another, such as from chemical energy in food to mechanical energy in muscle contractions or from light energy in photosynthesis to chemical energy in glucose.

In membrane biology, this principle plays a crucial role in processes like active _______ __________ _____ ________ _____ _______.
