The function of a protein determined by:

The shape determines the working of a protein. A protein's design is determined by its primary structure i.e the amino acid sequence. The amino acid sequence within a protein is decided by the encoding arrangement of nucleotide in the gene (DNA).

The role of a protein is utterly dependent on its three-dimensional architecture (other than when it caters as food). This framework may be disturbed by a number of agents thereby denaturing the protein:

Variations in the pH (between charged amino acids the electrostatic interactions is changed).difference in concentration of salt (does the same).temperature change (higher temperatures decrease the strength of hydrogen bonds).reduction agent presence (disruption of S-S bonds among cysteines).

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
