ATP yield
ATP (adenosine triphosphate) is the primary energy currency cells use for various functions. When your body breaks down nutrients like glucose during cellular respiration, energy is released, and a portion is stored as ATP. The efficiency of this process is measured by how much ATP is produced per molecule of nutrient, with glucose typically yielding about 30-38 ATP molecules. This ATP provides energy for activities such as muscle contraction, nerve signaling, and maintaining cell functions. Overall, ATP yield reflects how effectively your cells convert food into usable energy.
