the cells and its environment from reaching equilibrium. This lack of equilibrium is the driving force for gradient diffusion‚ allowing flow of materials. 8. Describe the structure of ATP (include a sketch) and identify the major class of macromolecules to which ATP belongs. ATP is made up of ribose‚ adenine‚ and a chain of three phosphate groups.

It’s necessary in the dev’t and enforcement in standard of identity‚ purity and feel of processed food products. 2. It can provide studies design to improve and control the quality of natural processed food. 3. Can help in the determination of the composition of products in their normal and abnormal storage conditions. Methods

lactose becomes anhydrous. Further heating of lactose to higher temperatures causes the lactose to decompose. This process is called pyrolysis. The primary reaction products of pyrolysis tend to polymerize‚ resulting in brown and black coloured macromolecules. Eventually the lactose becomes black on heating. Maillard reaction In aqueous solution‚ lactose‚ as all reducing sugars‚ tends to react with compounds possessing primary- and secondary amino-groups‚ such as proteins and peptides. This reaction

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA molecules are composed of two strands that form a helical ascending spiral. They fit together like the opposing teeth of a zipper and are held together by weak interactions called hydrogen bonds. These two strands is a long string of subunits called nucleotides‚ each attached to the one immediately about it and the one immediately below it to form a long chain. Each
