An exothermic chemical reaction is powered by ATP hydrolysis in the chloroplast
An endothermic chemical reaction provides the energy for ATP hydrolysis in the
The transport of ions across a membrane is powered by the tomat ATP ADP
inorganic phosphate
The movement of motor protein powered by
boto from ATP

Respuesta :

Answer:

b

Explanation:An endothermic chemical reaction provides the energy for ATP hydrolysis in the

The transport of ions across a membrane is powered by the tomat ATP ADP

During cellular respiration, the electron transport chain is coupled to the generation of an electrochemical gradient across the mitochondrial inner membrane.

  • The statement 'the movement of motor proteins is powered by the formation of ADP and inorganic phosphate from ATP' describes an energy-releasing process that is coupled to the energy-requiring process in the cell.

  • In cellular respiration, an electrochemical gradient is created by pumping ions (e.g. H+) against a concentration gradient from the mitochondrial matrix into the intermembrane space.

  • Subsequently, this gradient is used by a protein complex known as ATP synthase to generate ATP (the energy coin of the cell) from ADP and monophosphate.

In conclusion, the statement 'the movement of motor proteins is powered by the formation of ADP and inorganic phosphate from ATP' describes an energy-releasing process that is coupled to the energy-requiring process in the cell.
