Photosynthesis vs. Solar Cells When the subject of solar energy is discussed both the ideas and processes of photosynthesis and solar cells are the basis of these conversations. While both are processing or converting light into energy‚ which will be explained further‚ it is the type of energy that is vastly different. Photosynthesis as a process used by certain plants to convert the suns energy into food. When the electromagnetic energy from the sun reaches a green plant the chlorophyll

1. Glycolysis is a catabolic pathway through which glucose (C6H12O6) is oxidized to pyruvate (CH3COCOO−). It takes place in the cytosol of both eukaryotic and prokaryotic cells. During the first steps of glycolysis‚ 2ATP molecules are used to attach two phosphates to the glucose molecule‚ leaving a 6-carbon sugar diphosphate and 2 ADP molecules. Afterwards‚ the 6-carbon sugar diphosphate is split into two 3-carbon sugars by the enzyme Isomerase. The two 3-carbon sugar molecules then both undergo

using the smith fermentation tube method. The experiment used six smith fermentation tubes‚ distilled water and sugar substrates. It composed of six set-ups which used 15ml of 10% yeast suspension‚ 15 ml distilled water and 15 ml of their assigned sugar substrate namely: starch‚ lactose‚ sucrose glucose and fructose respectively. Set-up six was the controlled set-up and did not contain any sugar substrate. The opening of the tube was covered with a cotton ball to prevent oxygen from entering. The set-ups

Photosynthesis simply means the conversion of light energy into chemical energy by living organisms. In photosynthesis‚ the raw materials are water and carbon dioxide. Energy is taken from sunlight and the end products give out glucose and oxygen. It is the most important‚ naturally occurring process

for the energy that we‚ and all other organisms‚ need to survive. It is produced primarily in the processes of aerobic and anaerobic respiration by oxidative and substrate phosphorylation. 4 molecules of ATP are produced from 4 ADP and 4 inorganic phosphates in glycolysis in the cytoplasm of every cell‚ by the oxidation of a triose phosphate into two molecules of pyruvate. In anaerobic respiration these are the only 4 ATP molecules produced per molecule of glucose as there is no oxygen available

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. The reactions involved in respiration are catabolic reactions that involve the redox reaction

Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. Include in your paper: •Complete descriptions of photosynthesis and aerobic respiration. •Describe how these two processes are linked between plants and animals based on the reactants and products (water‚ carbon dioxide‚ glucose and oxygen) of both pathways. •Include a description of how energy is transferred from sunlight to ATP‚ from ATP to sugars‚ and from sugars to your

Glycolysis Regulation Task 3 (D4) Glycolysis is the breakdown of glucose into a compound called pyruvate. A net of two ATPs are produced as the process uses two ATPs and produces four. Glycolysis consists of ten chemical reactions; each reaction is catalysed using a different enzyme. Oxygen is not required during glycolysis so it is considered anaerobic respiration. Glycolysis must be regulated so that energy is produce only when required. During glycolysis there are three enzymes that catalyse

Importance of Photosynthesis and Respiration Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat: Photosynthesis is the process in which certain life forms are able to use sunlight to create energy. This energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Plants release large amounts of oxygen into the atmosphere as they produce much more than needed during the photosynthesis process.
