Proteins are made up of long chains of amino acids‚ just a chain of ami. tacids makes up the primary structure. The secondary structure is formed by hydrogen bonds joining the chains in certain places to make an alpha helix or a beta sheet. The tertiary structure is formed by even more folding and joining of the chains to make a globular mass or fibrous mass. An example of this would be a carrier protein. Proteins are needed for many things they are needed in our diet for growth and repair of cells

Dear Friend‚ My biology teacher‚ Mrs. Anderson‚ asked me to send you a note about the importance of chemistry in biology. Chemistry is an important part of biology. Modern biology overlaps with chemistry in explaining the structure and function of all cellular processes at the molecular level. Chemical principles are important in modern cell biology because all living cells are made up of chemicals and many chemical processes occur in various living organisms. In biology you learn about living

DEFINITIONS * Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy. * The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing (except virus‚ which consists only from DNA/RNA covered by protein and lipids)‚ and is often called the building block of life. Organisms can be classified
