Document Summary
Extra amino acids- break off amino group and use it for energy or store it for later in the form of fat. Protein turnover- as it breaks down protein, it can refill the amino acid pool. U don"t need to eat that much protein bc you reuse amino acids. Protein synthesis - amino acids put into different orders directed by dna. Dna - small segments - genes - become code for how the amino acids line up. Messenger rna - takes code out and transfer rna picks up amino acids and brings them back to be put into sequence. Enzymes are proteins - they allow for metabolic reactions to occur. If we don"t have enough -keep fluid balanced, if we don"t have enough then we can have deformities. Negative nitrogen balance - eating poorly but body has high demand for proteins - body starts breaking down amino acids for other things and gets excreted in large quantities.
