Question
3. Eukaryotic cells are generally more highly compartmentalized than prokaryotic cells. In addition to the nucleus, eukaryotes contain a number of subcellular membrane-enclosed organelles in the cytoplasm including, the endoplasmic reticulum, the Golgi, endosomes, hydrogenosomes, lysosomes, mitochondria, peroxisomes and, in photosynthetic organisms, chloroplasts. Additionally, eukaryotic cells also contain transport vesicles that move cargo among particular organelles and secretory vesicles that deliver cargo to the cytoplasmic membrane For each of the proteins below, list all of the subcellular organelles (indicated in bold type above) involved in its expression and targeting. For example, for the expression of a cytoplasmic protein, the mRNA for the gene encoding it is Problem Set 4, Spring 2018 transcribed in the nucleus and transported to the cytoplasm where the protein is translated and released, so an appropriate answer would be: nucleus and cytoplasm. A. a protein that is secreted from the cell B. a lysosomal protein C. a nuclear protein D. the envelope glycoprotein (env) of HIV-1 In which compartments do the following processes occur? E. oxidative phosphorylation F. hydrolysis of macromolecules (such as proteins, fats and carbohydrates) that are taken up from the extracellular space by endocytosis or phagocytosis G. photosynthesis H. transcription I. glycosylation of proteins J. sorting of proteins to appropriate organelles such as lysosomesExplanation / Answer
answerA) nucleus and secreatory vesicle formation.
answerB) nucleus, ENDOPLASMIC reticulum and lysosome.
answerc) nucleus and nucleus
answerd) nucleus and HIV envelope formation.
answer E) mitochondria is the place where oxidative phosphorylation takes place. it is also known as the energy currency of the cell.
answer F) the function is performed by lysosomes which consist for various hydrolytic enzymes and help convert various polymer into monomer.
answer G) photosynthesis is the process by which plants makes their own food and utilize them the process takes plac in chloroplast which consist of grana and thalakoid membrane.
answer H) transcription is the process of formation of mRNA and which results in formation of proetins that protein function as an active enzyme and helps in completeing the reaction transcription enzymes are located in the nuclues and it also takes place the nuclues.
answer I) glycosylation is the procss of attachment of glycans to proteins this process occurs in golgi apparatus.
answer J)transporrt vesicle helps in transporting proteins to appropirate target orgenelle and ER that is endoplasmic reticulum also helps in transporting organelle.
