Which of the following membrane-enclosed organelles is the site of synthesis of membrane proteins and secretory proteins? a) rough endoplasmic reticulum b) smooth endoplasmic reticulum c) nucleus d) centrosome e) Golgi complex 35. Which of the following membrane-enclosed organelles modifies, s destined for other regions of the cell? sorts, and packages proteins a) endoplasmic reticulum b) Golgi complex c) peroxisomes d) nucleus e) proteasome 36. Which of the following membrane-enclosed organelles contains several oxidases that are involved in oxidation of fatty acids and...
discuss the cellular anatomy for the synthesis and translocation of proteins found in the cytoplasm, nucleus, mitochondria, Endoplasmic recticulum, lysosomes and membranes
hich of the following organelles are the destination for proteins synthetized by cytosolic ribosomes Peroxisomes, endoplasmic reticulum, and the Golgi apparatus The Golgi apparatus, lysosomes, and the nucleus Peroxisomes, mitochondria, and lysosomes Peroxisomes, mitochondria, and the nucleus Mitochondria, lysosomes, and the nucleus What is the fate of N-terminus signal peptide after it directs the protein to the ER translocator O It is linked to the transported protein by S-S bond It is cleaved and then released into the membrane It...
4. Ex plain how proteins produced in the rough endoplasmic reticulum can be secreted into the extracellular environment without ever crossing the plasma membrane. Use the terms rough endoplasmic reticulum ribosome, lumen, Golgi apparatus, cell membrane in your answer.
Chapter 4: A Tour of the Cell 3. A cell's plasma membrane is described as being a because it is composed of a variety of molecules that are constantly in motion around each other. 4. Figure 4.4b on pg. 60 of your textbook indicates that membrane proteins will have both hydro- philic and hydrophobic regions. Briefly explain why a membrane protein would need both regions. Refer to the figure to aid you in answering the question. Chapter Content: The Nucleus...

Question 5 Speaking of mitochondria. Get your cell biology textbook and review how mitochondria generate ATP. Then consider - some researchers though they had found a wonder diet drug when they discovered molecules that increased the basal metabolic rate by allowing protons to leak across the inner mitochondrial membrane. A) Describe how these drugs would cause an increase in the basal metabolic rate (that is, the cells are burning more ‘food’ but the organism isn’t doing more ‘work’). B) What...
