Protein Article Search I reviewed “6 Biggest Nutritional Problems Solved” (2008) written by Chris Aceto and Eric Velazquez on the subject of amino acids and how they relate to athletics. The authors believe body builders commonly go overboard in their quest for muscular bodies and neglect key ingredients necessary for muscle production. This relates to amino acids because the authors suggest that athletes frequently leave out fats and proteins made from amino acids. The authors state that

Would you find proteins inside cells or cells inside proteins? (Choose one answer.) * Proteins are found inside the cell‚ because proteins are a macromolecule. 5.

The ROUGH EDOPLASMIC RETICULUM looks rather “pebbeled” through a microscope because of the ribosome’s that are present on the surface. The ribosomes have under gone protein synthesis and so they collect here to be transported to the Golgi apparatus. The SMOOTH EDNOPLASMIC RETICULUM appears “smooth” through a microscope (hence
