The light reactions absorb light and harness the energy to powder electron transfers. Glucose and oxygen D. The first stage is called the light-dependent process, or light reactions, because it requires sunlight. The Carbon Cycle Back to Top Plants may be viewed as carbon sinks , removing carbon dioxide from the atmosphere and oceans by fixing it into organic chemicals.
Chlorophyll , the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects to be detected by our eyes. The energy transfer is similar to the chemiosmotic electron transport occurring in the mitochondria. This results in fish kills and changes in soil pH which can alter the natural vegetation and uses of the land. Chlorophyll is a complex molecule. The sugars are synthesized made during photosynthesis.
Cyclic Electron Flow occurs in some eukaryotes and primitive photosynthetic bacteria. Wavelength and other saspects of the wave nature of light. Increasing levels of CO2 appear to go hand in hand with increasing global temperature "Global Warming". The leaves of plants are the photosynthesis factories.
Several modifications of chlorophyll occur among plants and other photosynthetic organisms. Oxygen is also formed.
The rate of metabolic reactions is determined in part by the maturity of the organism and whether it's flowering or bearing fruit. This question can be answered on various levels.
I should mention that glucose may be used for things other than energy.
Light energy causes the removal of an electron from a molecule of P that is part of Photosystem II. The longer the wavelength of visible light, the more red the color. The product of that reaction forms glycolic acid, a chemical that can be broken down by photorespiration, producing neither NADH nor ATP, in effect dismantling the Calvin Cycle.
The structure of the chloroplast and photosynthetic membranes The thylakoid is the structural unit of photosynthesis.
While the mitochondrion has two membrane systems, the chloroplast has three, forming three compartments. Don't you agree? Thylakoids are stacked like pancakes in stacks known collectively as grana. Carbon dioxide enters single-celled and aquatic autotrophs through no specialized structures, diffusing into the cells. These three molecules make up the core of a photosystem.
One product of photosynthesis is glucose sugar , which provides the basis for most food chains.
Nutrition has to do with how organisms obtain the materials necessary for energy, growth, etc. So, it's a good idea to know the overall reactants and products for the photosynthesis general equation, the light reactions, and the dark reactions. Most photosynthetic organisms capture visible light, although there are some that use infrared light. Remember the complexity of life, each reaction in this process, as in Kreb's Cycle, is catalyzed by a different reaction-specific enzyme. Unfortunately, this won't be an open-ended question, which you could easily answer with "iron" or "a car" or "your mom.
