that the stomatal density on high leafs is higher than on low leafs. During photosynthesis the chloroplasts in the leaf cells synthesize ATP from ADP as a result of exposure to light‚ while oxygen is produced as a by-product of the photosynthetic reaction. Carbon dioxide‚ which enters the plant through diffusion via the stomata‚ is needed for this process (photosynthesis) to occur. When the chloroplasts in the leafs cell is exposed to higher light intensities‚ more ATP is synthesized from ADP‚ while

rate of reaction of the enzyme catalase. Background Information: Enzymes such as catalase are globular protein molecules with catalytic properties. A catalyst is a substrate which can alter the rate of reaction without itself undergoing any permanent change. As they are not changed my reactions which they catalyse‚ enzymes can be used over and over again. They are therefore quite effective in small amounts. All enzymes are specific as each one performs a particular reaction. Catalase

Properties of Chemical Reactions Ms. Whitty‚ Science 10 Fiona Adams‚ November 1st‚ 2012 Introduction Chemical reactions are a part of our daily lives‚ from rusting metal to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical reaction takes place‚ the change is indicated by one or more qualitative properties. The colour or odor could change‚ gas could be produced
