WebFriday, November 18, 2024 BI 110 – Chapter 6 (Lecture 30) Chapter 6 – Photosynthesis Photosynthesis -Photosynthesis is the use of light energy to convert carbon from CO2 gas into an organic form. Oxygen, generated from the oxidation of H2O during the process, is released as a by-product.-Provide the source of all the food we eat, through direct … WebPhotorespiration is a metabolic pathway that occurs in photosynthetic organisms and releases carbon dioxide, consumes oxygen, and produces no chemical energy or food. This process limits the growth rates of plants.
WebJul 30, 2024 · Oxaloacetate is then converted to a similar molecule, malate, that can be transported in to the bundle-sheath cells. Inside the bundle sheath, malate breaks down, releasing a molecule of CO 2. The CO 2 is … WebIn the photorespiration pathway, 6 O2 molecules combine with 6 RuBP acceptors, making 6 3-PGA molecules and 6 phosphoglycolate molecules. The 6 phosphoglycolate molecules enter a salvage pathway, which converts them into 3 3-PGA molecules and … When you start out with 3 RuBP there are 6 phosphates, and after you add 3 CO2 … C-4 photosynthesis is photosynthesis used for specific C-4 plants, and instead of … Due to excessive heat the stomata remains closed during the day to reduce …
