Dehydration synthesis is a process where formation of a water molecule takes place while joining two molecules. Hydrolysis refers to a chemical reaction where breakdown of water molecule takes place. Thus, both the processes are opposite to each other but are related to each other while harnessing energy from the food. During dehydration synthesis the food molecule is formed with extraction of water from the food while during hydrolysis digestion of food particle takes place and water molecule is used in the process.
The levels of protein structures are: PRIMARY, SECONDARY AND TERTIARY STRUCTURES.
The amino acid sequence and the bonding types between the amino acids determine the structures of proteins. Protein structures also determines the function of a protein, if a protein losses its structure it will not be able to perform its function again.
Functional groups play an important role in the formation of protein structure.Functional groups also participates in specific biochemical reactions in the body thus enabling the proteins to perform their functions.
The assortment of genes is determined by metaphase 1 and 2 because thisnis where the chromosomes line up and where they will be sent (and separated) is determined now.
