FL #23 The role of Ribosomes, Golgi Apparatus and Endoplasmic Reticulum in the Production, Storage and Secretion of Proteins. Cell Biology Standard 1E. The learner will be able to know the role of the endoplasmic reticulum and Golgi apparatus in the secretion of proteins. February 4, 2003 Submitted by: Tony Gonzales Animal Cell Eukaryotic Cells Animal Cell Prokaryotic Cells Bacterial Cells The path of proteins in cells. Ribosomes - (make proteins) Rough Endoplasmic Reticulum – Assists in protein synthesis by processing & packaging proteins for storage or export.) Golgi Apparatus - (additional packing & destination package is given to proteins staying or leaving) Cell Membrane - Proteins Are Secreted Ribosomes Places where MRNA is decoded to assemble Amino Acids into protein. Ribosomes produce proteins for the cells that contain them. Animal Cell Rough Endoplasmic Reticulum Assist in synthesizing and processing proteins. Its main job is to separate & process proteins that are staying from those that are needed by other cells. Golgi Apparatus Further packages proteins for export or storage. It also gives destination package for use by other cells. Animal Cell Animal Cell Cell Membrane Controls what enters and leaves the cell. Defines the cell shape in animal cells. The path of proteins in cells. Ribosomes - (make proteins) Rough Endoplasmic Reticulum – Assists in protein synthesis by processing & packaging proteins for storage or export.) Golgi Apparatus - (additional packing & destination package is given to proteins staying or leaving) Cell Membrane - Proteins Are Secreted 1. What is an important life molecule made by the ribosomes that controls what we are, what we do and what we look like? A. DNA C. Carbohydrate B. Protein D. Lipid Animal Cell 2. What organelle makes proteins by assembling or putting together amino acids? A.Cell Wall B. Cell Membrane C. Nucleus D. Ribosome Animal Cell 3. What part of the cell is the arrow pointing to? A.Cell Wall B. Cell Membrane C. Nucleus D. Ribosome 4. The rough endoplasmic reticulum primary function is in? A. processing proteins for export B. Store of genetic information C. Translates info encoded in mRNA D. Assist in Protein Synthesis 5. The transport of molecules within animal cells is assisted by a system of internal membranes that make up the A. Chloroplast B. Mitochondria C. Ribosomes D. Cell membrane E. Endoplasmic Reticulum Animal Cell Animal Cell 6. What part of the cell is the arrow pointing to? A.Golgi B. Endoplasmic Reticulum C. Cell wall D. Cell membrane 6. What is the function of the golgi body? A.Assemble amino acids into proteins. B.Regulate what enters & leaves cell. C.Concentrates & packages proteins for storage or export. D.Makes ribosomes 7. The golgi body is primarily responsible for what cell process? A. Synthesizing proteins B. Store genetic information C. Translate info encoded in mRNA D. Gives destination package to proteins Animal Cell 8. What part of the cell is the arrow pointing to? A.Golgi B. Endoplasmic Reticulum C. Nucleus D. Ribosome
