... storage units for glucose and fuel synthesis. These reactions provide the backbone on which all ecosystems and food webs are based upon. Photosynthesis requires several raw materials in order to function. These include an external energy source (sunlight), carbon dioxide, and water. Photosynthesis processes start with the absorption of sunlight for the breakdown of producing the constituent parts of ... maximum effect on photosynthesis. In the experiment, the idea that "different colored lights may affect the photosynthesis process" was tested. The hypothesis to the experiment states tha...

... the wavelength of solar radiation known as ultraviolet-B (UV-B). UV-B damages deoxyribonucleic acid (DNA), the genetic molecule found in every living cell, increasing the risk of such problems as cancer in humans. Because of its protective function, the ozone layer is essential to life on earth. Several pollutants attack the ozone layer. Chief among them is the class of chemicals ... lower pollution overall, industrial polluters are sometimes allowed to make cooperative deals. For instance, a power company may fulfill its pollution control requirements by investing in pollution control a...

... an increase in the surrounding temperature has on the plasma membrane of a typical plant cell structure. Hypothesis: An increase in temperature will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within the membrane to leak out. Introduction: The purpose of a cell membrane is to control the transport of substances moving into and out of ... one molecule of glycerol chemically linked to three molecules of fatty acids. The majority belongs to one subgroup of triglycerides known as phospholipids. Despite their many differences in appearance a...

... life, without water life on earth would not exist. Water is a major part of cells, forming between 70 and 95% of the mass of the cell. This means that we are made from approximately 80% water by mass and some soft bodied creatures such as jellyfish are made of up to 96% ... plants have moist surfaces in their leaves (the mesophyll cells) for gas exchange. The use of water as a solvent in humans is very extensive. A main function is to transport materials around the body to where they are needed. Blood plasma, tissue fluid and lymph are all mainly water and are used to dissolve a ... wa...

... of catalase. Catalysts accelerate chemical reactions that otherwise proceed slowly. The enzyme called catalase is a catalyst. It exists in plant and animal cells and breaks down hydrogen peroxide, H2O2, which is a byproduct of metabolism. Hydrogen peroxide is toxic if it accumulates in a cell. The chemical reaction accelerated by catalase is written 2H2O2 > 2H2O + O2 (gas) The products of the above reaction are ... it will effect the reaction rate. Brief outline of how enzymes work An enzyme is a protein molecule that speeds up chemical reactions. Each enzyme has a unique shape that det...
