A plants volatile organic compound (VOC) composition is the hand that swats unwanted visitors‚ welcomes visitation from much needed pollinators‚ and the substantial determinant in a plants identity and overall evolutionary fitness within the plant community. Understanding the mechanics of volatile formation is essential in interpreting their importance in plant life‚ and in plant-animal interactions. A huge allocation of energy is assumed to be given to the production of volatiles‚ and is therefore

Def: An enzyme is a protein formed by the body that acts as a catalyst to cause a certain desired reaction. Enzymes are very specific. Each enzyme is designed to initiate a specific response with a specific result. There are many enzymes in the human body. In cystic fibrosis‚ the term enzyme generally refers to the enzymes created by the pancreas that are intended to initate a reaction that digests food. Structure :The basic mechanism by which enzymes catalyze chemical reactions begins with

This is done before the cellulose is broken down. The other method involves the usage of hydrolytic enzymes (Alexander N.Glazer). This enzyme catalysis the conversion of cellulose to another type of sugar called glucose. During this process the lignin is still undissolved and it is removed through a filtration process (Alexander N.Glazer). The glucose solution is then converted to alcohol through

Chapter 6 Explain what free energy is and how it can be used to predict the energetic outcome of chemical reactions.Free energy is defined as the energy available to do work in any system. The free energy is denoted by the symbol G. G = H – TS* H: the energy contained in a molecule’s chemical bonds‚ called enthalpy.* TS: the energy term related to the degree of disorder in the system. T is the absolute temperature (K)‚ and S is the entropy.We can use the change in free energy to predict whether

"Carbon-based polymers such as nucleic acids and proteins make up the core molecules required to carry out the central biological functions of replication and catalysis‚" (Wallace).
