Protein Synthesis

-20 different types of amino acids used in synthesis

- Amino acids bonded by peptide bonds

- Proteins differ due to amino acid sequence/length of chain

- Proteins are fibrous of globular

- Examples of fibrous proteins are collagen and keratin

- Examples of globular proteins are enzymes, hormones and antibodies

Uses of proteins

- Proteins in cell membranes control exchange of substances

- Enzymes bring about chemical reactions

- Hormones control growth and development

- Proteins in muscle tissue give movement

- Haemoglobin for transport of O2

- Antibodies to destroy antigens

Proteins Translation

- Packaging/processing within Golgi body

- Protein enclosed in a vesicle

- Vesicle fuses with membrane

- Protein secreted from cell
