Which of the following sequences accurately represents the flow of electrons through living organisms? water → photosynthesis → carbohydrate → cellular respiration → water oxygen → cellular respiration → carbohydrate → photosynthesis → carbon dioxide carbon dioxide → water → chlorophyll → carbohydrate → cellular respiration → ATP carbon dioxide → photosynthesis → carbohydrate → cellular respiration → ATP water → photosynthesis → carbohydrate → cellular respiration → ATP

Respuesta :

Answer;

A. light → photosynthesis → carbohydrate → cellular respiration → ATP → heat

Explanation;

  • Photosynthetic cells absorb the sun's radiant energy and use it to drive electrons from water to carbon dioxide, forming energy-rich products such as starch and sucrose.
  • Non-photosynthetic organisms obtain energy for their needs by oxidizing the energy-rich products of photosynthesis, passing electrons to atmospheric oxygen to form water, carbon dioxide, and other end products, which are recycled in the environment.
  • The flow of electrons involves oxidation-reduction reactions.
