The energy required for the mechanism of "active transport" comes from: 1.the reactants which yield ATP 2. the product of ATP decomposition 3. photosynthesis 4. cytokinesis

Respuesta :

Answer: 2. the product of ATP decomposition

Explanation:

The Adenosine  triphospahte ATP is an energy currency made up,of 3 phospahte ions bonded to adenosine molecule

Each of these inorganic ions is  bonded to Adenosine molecule by certain bond energy.Therefore the hydrolysis of these phosphate ions release equal amount of  ENERGY  of value

ATP HYDROLYSIS  ADP + P(ions)

(30,5kj/mol) of energy  for the first 2 inorganic phosphate hydrolysed, and 14.2kjmol for the  last inorganic phosphate.
