Kids Research Express: How Photosynthesis Works
http://kidsresearchexpress.blogspot.com/2008/08/how-photosynthesis-works.htmlChlorophyll and the other pigments are clustered next to one another in the photosystems, and the vibrating energy passes rapidly from one chlorophyll or pigment molecule to the next, like the transfer of energy in billiard balls.Light contains many colors, each with a defined range of wavelengths measured in nanometers, or billionths of a meter. Plants range in size and complexity from small, nonvascular mosses, which depend on direct contact with surface water, to giant sequoia trees, the largest living organisms, which can draw water and minerals through their vascular systems to elevations of more than 100 m (330 ft).
Of course animals such as humans require oxygen to breath and this life-sustaining substance is released as a waste product from the photosynthesis process. As a plant takes in sunlight and begins the photosynthetic process, it also takes in six molecules of H20, or water, and six molecules of CO2, or carbon dioxide, which it uses in the production of each molecule of sugar
While the molecules are being rearranged in this cycle, carbon dioxide is produced, and electrons are pulled off and passed into an electron transport system which, just as in photosynthesis, generates a lot of ATP for the plant to use for growth and reproduction. They conserve water a lot better than we do.Can plants live without animals? Can animals live without plants?Thanks for asking.Click Here to return to the search form

How many net number of ATP molecules are produced from Palmitic acid during beta oxidation process? - ResearchGate
Siva Kumar Sri Sankara Arts and Science College How many net number of ATP molecules are produced from Palmitic acid during beta oxidation process? The answer is 129. But if you go with the thereotical yields and have larger production ATP source then values of NADH, FAD and ATP produced by the full rotation of citric acid cycle will produce 3, 2, 12 ATPs
Photosynthesis
These high-energy electrons will be used in the Calvin Cycle to reduce CO2 to make sugars The H+ is pumped into the thylakoid membrane to generate an H+ gradient (i.e. Each arrow in the diagram above actually represents a reaction like this one: Each element in the pathway is reduced by the electrons, and turns right around to reduce its neighbor in the pathway by giving it the electrons, thus becoming reoxidized and ready for the next electrons to pass through the photosystem H+ Pumping
In this case, carbon dioxide gets used to produce sugars in a series of reactions called the Calvin Cycle, C4 photosynthesis, and crassulacean acid metabolism. There are a couple of ways this works in cells: -glycolysis, in which glucose is broken up into two subunits, called pyruvate, which creates two units of ATP per molecule of glucose
Cellular Respiration
What is the chemical formula for glucose? The chemical equation for respiration is: C6H12O6 + 6O2 6CO2 + 6H2O Glucose + Oxygen Carbon Dioxide + Water The key points: Glucose stores the sun's energy in chemical form. Electron transport produces an uneven charge on the mitochondria membrane.This allows protons to move through the membrane by electrical charge attraction
How many ATP molecules are produced by one molecule of glucose
The formation of ATP from ADP requires energy, thus ATP can be synthesized through the energy released by the splitting of a higher-energy phosphate molecule. Some high-energy phosphate molecules have a lower free energy of hydrolysis than ATP, meaning more energy is released by the removal of a phosphate group
