This energy is essential for carrying out various cellular activities, including growth, repair, and signaling.

Introduction to Cellular Metabolism

The Role of ATP

Central to cellular metabolism is adenosine triphosphate (ATP), often referred to as the “energy currency” of the cell. ATP serves as a source of energy for cellular processes by undergoing hydrolysis, releasing energy that powers biochemical reactions. These reactions include muscle contraction, nerve impulse propagation, and biosynthesis of cellular components.

Mitochondria: Powerhouses of the Cell

Mitochondria are organelles known as the powerhouses of the cell due to their role in ATP production. Through a process called oxidative phosphorylation, mitochondria generate the majority of ATP in eukaryotic cells. This process involves the transfer of electrons along the electron transport chain, coupled with the synthesis of ATP by ATP synthase. Mitochondria also play a crucial role in regulating cellular metabolism by integrating signals from various metabolic pathways.

Oxidative Stress and Reactive Oxygen Species

While mitochondria are essential for energy production, they also produce reactive oxygen species (ROS) as byproducts of metabolism. ROS, including free radicals like superoxide and hydroxyl radicals, can cause damage to cellular components such as DNA, proteins, and lipids. This oxidative stress can contribute to various health issues, including aging, inflammation, and disease.

Regulation of Cellular Metabolism

Cellular metabolism is tightly regulated to maintain energy homeostasis and adapt to changing environmental conditions.
