Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However‚ the reactants and the products are exact opposites in photosynthesis and 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

respiration where large molecules are broken down into smaller ones with energy released. An example of an anabolic reaction is photosynthesis where small molecules are built up into larger ones using energy. ATP is built up from ADP and inorganic phosphate ions (3-4 PO‚ abbreviated to Pi) by condensation and is then hydrolysed by the enzyme ATPase to ADP and Pi to release energy that can be used for energy requiring reactions such as photosynthesis in plants. Plants are able to produce ATP during

Aerobic vs Anaerobic Cardiovascular vs Resistance Training I’ve heard the terms aerobic and anaerobic a lot. What do these terms actually mean and are they important for my exercise program? ANSWER: Strictly speaking‚ the terms "aerobic" and "anaerobic" refer to the presence and absence of oxygen‚ respectively. Most of our cells prefer to get their energy by using oxygen to fuel metabolism. During exercise with adequate fuel and oxygen (i.e.‚ aerobic)‚ muscle cells can contract repeatedly

The Molecules of Cells (Chapter 3 in your textbook) Without water and carbon-based molecules‚ no life as we know it! Carbon: The Backbone of Life • Living organisms consist mostly of carbon-based compounds Also‚ H‚ N‚ O‚ P‚ and S…… • Carbon is unparalleled in its ability to form large‚ complex‚ and diverse molecules. Why? Principal source of carbon on Earth? • Proteins‚ DNA‚ carbohydrates‚ lipids‚ and other molecules that distinguish living matter are all composed of carbon. C21H36N7O16P3S Coenzyme
