Write a word equation to summarise photosynthesis
It is the only biological process that captures energy from outer space sunlight and converts it into chemical energy in the form of G3P Glyceraldehyde 3-phosphate which in turn can be made into sugars and other molecular compounds. Oxygen is also formed. Light-Independent Reactions In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. Chloroplasts have a double inner and outer membrane. To get this energy, many organisms access stored energy by eating food. Answers 1. The Process of Photosynthesis During photosynthesis, molecules in leaves capture sunlight and energize electrons, which are then stored in the covalent bonds of carbohydrate molecules. Photosynthesis also results in the release of oxygen into the atmosphere. Cottonwood trees, for example, will lose gallons about dm3 of water per hour during hot desert days.
Additional Self Check Questions 1. Overview of Photosynthesis The Purpose and Process of Photosynthesis The process of photosynthesis converts light energy to chemical energy, which can be used by organisms for different metabolic processes.
But where does the stored energy in food originate? Key Terms chloroplast: An organelle found in the cells of green plants and photosynthetic algae where photosynthesis takes place.
The energy used to hold these molecules together is released when an organism breaks down food. The photosynthesis connection applies to every meal and every food a person consumes. After the energy is transferred, the energy carrier molecules return to the light-dependent reactions to obtain more energized electrons.
Equation of photosynthesis and respiration
October 16, It is the only biological process that captures energy from outer space sunlight and converts it into chemical energy in the form of G3P Glyceraldehyde 3-phosphate which in turn can be made into sugars and other molecular compounds. In photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. Section Summary The process of photosynthesis transformed life on earth. References "Advanced Biology;" M. Carbon dioxide cannot pass through the protective waxy layer covering the leaf cuticle , but it can enter the leaf through the stoma the singular of stomata , flanked by two guard cells. In photosystem I, the electron comes from the chloroplast electron transport chain. Embedded in the thylakoid membrane is chlorophyll, a pigment that absorbs certain portions of the visible spectrum and captures energy from sunlight. Unfortunately for the plant, while these gases are moving between the inside and outside of the leaf, a great deal of water is also lost. In most plants, water is supplied from the roots, with the leaves collecting carbon dioxide via the stomata and sunlight captured by the chloroplasts in the leaves.
In addition to glucose, this reaction produces oxygen that is released by the plants into the atmosphere.
