- Light energy comes from the Sun. The oxygen produced is released into the air from the leaves. The glucose produced can be turned into other substances, such as starch and plant oils, which are used as an energy store. The glucose is also used to release energy through the process of respiration.

Aug 15, 2018 · Cellular respiration involves the breakdown of glucose and the storage of the energy received into the molecule ATP. Plants create their own energy through photosynthesis and also use cellular respiration to produce ATP.
Aug 31, 2022 · Q1. What role does oxygen play in photosynthesis and cellular respiration? Ans. Oxygen is released as a byproduct in photosynthesis, whereas, in cellular respiration, oxygen helps to oxidize glucose to liberate energy.
May 14, 2022 · Light is absorbed by the antenna pigments of photosystems II and I. The absorbed energy is transferred to the reaction center chlorophylls, P 680 in photosystem II, P 700 in photosystem I. Absorption of 1 photon of light by Photosystem II removes 1 electron from P 680.
The light reactions of photosynthesis liberate oxygen, and more oxygen dissolves in the cytosol of the cell at higher temperatures. Therefore, high light intensities and high temperatures (above ~ 30°C) favor the second reaction and result in photorespiration.
Oct 10, 2024 · Photosynthesis captures light energy to produce glucose and oxygen, which serve as substrates for respiration. In turn, respiration releases carbon dioxide and water, substrates that are reused in photosynthesis.
Aug 3, 2023 · Photosynthesis is a light-driven oxidation-reduction reaction where the energy from the light is used to oxidize water, releasing oxygen gas and hydrogen ions, followed by the transfer of electrons to carbon dioxide, reducing it to organic molecules.
Feb 14, 2024 · Plants capture light energy and produce sugars through photosynthesis and break down these sugars through aerobic cellular respiration. They respond to a variety of environmental conditions through growth changes, life events like germination or flowering, and even, in special cases, through movement.
