ATP can be produced by a number of distinct cellular processes; ... Each equivalent of ATP is recycled 1000–1500 times during a single day (150 / 0.1 = 1500), ...
Three processes can synthesize ATP: ATP–CP system (phosphagen system) – At maximum intensity, this system is used for up to 10–15 seconds. [5] The ATP–CP system neither uses oxygen nor produces lactic acid if oxygen is unavailable and is thus called alactic anaerobic. This is the primary system behind very short, powerful movements like ...
Cellular waste products are formed as a by-product of cellular respiration, a series of processes and reactions that generate energy for the cell, in the form of ATP.One example of cellular respiration creating cellular waste products are aerobic respiration and anaerobic respiration.
The overall reaction can be expressed this way: [citation needed] Glucose + 2 NAD + + 2 P i + 2 ADP → 2 pyruvate + 2 NADH + 2 ATP + 2 H + + 2 H 2 O + energy. Starting with glucose, 1 ATP is used to donate a phosphate to glucose to produce glucose 6-phosphate. Glycogen can be converted into glucose 6-phosphate as well with the help of glycogen ...
Importantly, under low-oxygen (anaerobic) conditions, glycolysis is the only biochemical pathway in eukaryotes that can generate ATP, and, for many anaerobic respiring organisms the most important producer of ATP. [7] Therefore, many organisms have evolved fermentation pathways to recycle NAD + to
Creatine is found in vertebrates, where it facilitates recycling of adenosine triphosphate (ATP), primarily in muscle and brain tissue. Recycling is achieved by converting adenosine diphosphate (ADP) back to ATP via donation of phosphate groups. Creatine also acts as a buffer. [2]

Electron transport chains often produce energy in the form of a transmembrane electrochemical potential gradient. The gradient can be used to transport molecules across membranes. Its energy can be used to produce ATP or to do useful work, for instance mechanical work of a rotating bacterial flagella.
