Respuesta :

Answer:

c. both photosynthesis and respiration.

Explanation:

In photosynthetic cells, synthesis of ATP by the chemiosmotic mechanism occurs during photosynthesis and respiration.

+ aerobic respiration uses oxygen and produces carbon dioxide

+ photosynthesis uses carbon dioxide and produces oxygen

In photosynthetic cells, synthesis of ATP by the chemiosmotic mechanism occurs during both photosynthesis and respiration.

Chemiosmotic mechanism is the diffusion of ions through a selective permeable membrane, chloroplasts use chemosmosis to generate ATP during photosynthesis and in cellular respiration it occurs in the mitochondria.

  • The energy released by electrons "going down" an electron transport chain is used to establish a proton gradient across an inner membrane of the organelle.

  • When protons subsequently flow down this electrochemical gradient, the released potential energy is captured at the terminal phosphate bonds of ATP.

  • In this way ADP is phosphorylated to ATP in mitochondria and chloroplasts.

Therefore, we can conclude that in photosynthetic cells, synthesis of ATP by the chemiosmotic mechanism occurs during both photosynthesis and respiration.
