The ATP Cycle
SLCC BIOL Videos・1 minute read
ATP is the main energy source for cells, powering essential chemical reactions, with its structure resembling a nucleotide with three phosphate groups. The breaking of a phosphate bond in ATP releases energy, forming ADP, and cellular respiration replenishes ATP by adding a phosphate group through an anabolic dehydration synthesis process.
Insights
- ATP is the key energy currency for cells, fueling essential reactions in living organisms by breaking phosphate bonds to release energy.
- Cellular respiration is a vital process that regenerates ATP from ADP by adding a phosphate group, a crucial step in maintaining the energy flow necessary for cellular functions.

ATP: Cell Energy Source and Cycle
- ATP, or adenosine triphosphate, is the primary energy source for cells, powering most chemical reactions requiring energy within organisms.
- The structure of ATP resembles a nucleotide, with three phosphate groups, a ribose sugar, and the nitrogen-containing base adenine.
- Breaking a phosphate bond in ATP results in adenosine diphosphate (ADP) and an inorganic phosphate group, releasing energy in a hydrolysis reaction.
- Cellular respiration replenishes ATP by adding a phosphate group to ADP, requiring energy from food molecules through an anabolic dehydration synthesis process.
