photosynthetic rate. Photosynthesis at low temperatures actually take CO2 more efficiently. The rate of photosynthesis is decreased by higher oxygen concentrations. Lower temperatures inhibit Rubisco and forces this enzyme to to work competitively. Rubisco works competitively because is actually binds itself to oxygen rather than binding to carbon dioxide because of the mere attraction. Therefore‚ in doing so‚ this activates photorespiration rather than photosynthesis. Photosynthesis in corn is different

energy by converting carbon dioxide and water into glucose and oxygen‚ known as a process called photosynthesis. By adding hydrogen ions to carbon dioxide C-H bonds are made that hold energy which is released in mitochondrion‚ an organelle. This process of the release of energy is known as respiration. Without respiration‚ photosynthesis would not be able to perform. The process of photosynthesis is able to perform its duties with the help of an organelle called chloroplast as well. Within the

purpose of photosynthesis is to use carbon dioxide and water to form glucose. The reactants of photosynthesis are thus water and carbon dioxide which yield glucose and oxygen as a byproduct. The process of photosynthesis is divided into two parts. The first part is known as the light-dependent reactions which undergo in the thylakoid membrane of the chloroplast‚ and the second part is the calvin cycle which occurs in the chloroplast stroma. In order for a plant to undergo photosynthesis‚ it requires

This report will cover what photosynthesis is ‚ the factors which may affect photosynthesis in working poorly‚ light independant and dependant reaction. An investigation will be carried out which will include the factors that affect photosynthesis. What is photosynthesis? Photosynthesis is a process which occurs in plants

energy. 9. Explain how C4 photosynthesis is based on a spatial arrangement of structures‚ whereas CAM photosynthesis is temporally based. C4 photosynthesis is based on a spatial arrangement of structures because in C4 plants‚ light and carbon reactions are separated into different cells. The light reactions along with a carbon-fixation reaction occur in mesophyll cells‚ but the Calvin cycle occurs in the inner ring of bundle-sheath cells. However‚ CAM photosynthesis is temporally based because

If water was opaque‚ the sunlight wouldn’t be able to enter. Because they wouldn’t be able to conduct photosynthesis‚ plants would be unable to grow underwater.

stored carbon‚ which was gained during photosynthesis. Photosynthesis is the reverse process of respiration. Cellular respiration requires oxygen (which is the byproduct of photosynthesis) and it produces carbon dioxide‚ which is used in photosynthesis. In this way‚ photosynthesis and cellular respiration are linked in the carbon cycle. Respiration and photosynthesis are essentially the same process‚ just in reverse. Respiration adds CO2 and photosynthesis takes CO2 out of the atmosphere‚ they work
