cellular metabolism
Cellular metabolism refers to the complex set of chemical reactions that occur within cells to convert nutrients into energy and building blocks for growth and repair. It encompasses two main processes: catabolism, where larger molecules are broken down to release energy (like digesting food), and anabolism, where energy is used to build up components like proteins and fats. This metabolism is essential for maintaining cellular functions, supporting life, and enabling activities such as movement, reproduction, and response to the environment. Essentially, it's how cells harness energy and resources to sustain themselves and perform their tasks.

Cellular metabolism is the process by which cells convert food into energy and building blocks necessary for growth and maintenance. It involves two main types of reactions: catabolism, which breaks down nutrients to release energy, and anabolism, which uses that energy to build molecules like proteins and DNA. This energy is often stored in a molecule called ATP (adenosine triphosphate), which cells use to power various functions. Essentially, cellular metabolism is vital for life, allowing organisms to carry out essential processes such as movement, reproduction, and response to their environment.

Cellular metabolism refers to the complex set of chemical processes that occur within living cells to convert food into energy. Think of it as the body's power plant: cells break down nutrients from the food we eat, such as carbohydrates, proteins, and fats, to produce energy needed for growth, repair, and daily activities. This energy is stored in molecules like ATP (adenosine triphosphate) and is used for various functions, including movement, temperature regulation, and cellular repair. Essentially, metabolism is how cells manage energy to keep the body functioning efficiently.
