Photosynthesis is the process by which plants synthesize glucose from carbon dioxide and water. The energy of the reaction is supplied by the sunlight. However‚ there are two main stages in photosynthesis - light-dependent and light-independent stages. [11] The light-dependent stage depends on the light because the energy

dichotomously-branching arbuscules. Arbuscular mycorrhizae are known to be heterkaryon‚ goining through both asexual and sexual reproduction. * The hyphae of arbuscular mycorrhizal fungi produce the glycoprotein glomalin‚ which may be one of the major stores of carbon in the soil. Arbuscular mycorrhizal fungi have (possibly) been asexual

group. A carbonyl group is a carbon atom doubly bonded to an oxygen atom. [pic] Both molecules have a carbonyl group‚ the difference the number of carbons bonded to the carbonyl carbon. An aldehyde will have none or one and a ketone will have two carbons. All aldehydes‚ except formaldehyde‚ will have a hydrogen atom on one side of the carbonyl carbon and at least on carbon on the other side. [pic] All ketones have a carbon on each side of the carbonyl carbon. [pic] Remember that the

- Cellular Respiration Assignment - 1. What two molecules are formed when a phosphate is removed from ATP? There are three phosphate groups in ATP molecule (Adenosine Triphosphate)‚ when removing one phosphate molecule‚ ADP molecule is formed (Adenosine Diphosphate). 2. What is the function of ATP? Describe the molecule. The function of ATP is storing energy within a cell. ATP is adenosine triphosphate‚ C10H16N5O13P3‚ a high energy complex‚ giving the necessary power to push metabolistic

triose phosphate. Step 3 - Each triose phosphate molecules is oxidised. Two atoms of hydrogen are removed from each molecule. The energy released by the oxidation is used to add another phosphate group to each molecule. This will result in two 3-carbon compounds‚ each carrying two phosphate groups. NAD+ is the hydrogen carrier that accepts the hydrogen atoms lost from each triose phosphate molecule. Step 4 - Two pyruvate molecules are formed by removing two phosphate groups from each molecule

in cellular respiration. In photosynthesis‚ cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun‚ and then the cells release oxygen (O2) and store glucose (C6H12O6). The formula of photosynthesis is: Light energy 6CO2+6H2O → C6H12O6+6O2 In cellular respiration‚ glucose and oxygen are taken into the cells‚ then they are converted to carbon dioxide‚ water and ATP energy and some other energy. Some of the
