This intricate dance is orchestrated by various physiological mechanisms that impact our overall well-being.
The Role of Mitochondria
Mitochondria, often referred to as the powerhouses of the cell, play a pivotal role in energy production. These tiny organelles utilize oxygen to generate adenosine triphosphate (ATP), the primary currency of energy in cells. Through aerobic metabolism, mitochondria convert carbohydrates, fats, and proteins into ATP, fueling cellular processes essential for muscle contraction, nerve transmission, and overall vitality.
Neurotransmitters and Exercise
