How does a cell regulate location of proteins? Explain 4 specific examples.
PROTIENS:THIS HELPS IN FUNCTIONING OF OUR CELLS IN PROPER MANNER
THE FUNCTION AND STRUCTURE OF OUR BODY DEPENDS UPON PROTEINS..
THESE CONTAINS AMINO ACIDS
PROTEINS CAN BE LOCATED BY THE HELP OF AMINO ACIDS
CELLS ARE IN DIFFERENT TYPES
THEY ARE LIKE
NUCLUEUS
CYTOSOL
MITHOCHONDRIA
ENDOPLASMIC
RETICULUM
PROTEINS ARE SECRETD FROM THE CELLS
IT CAN BE LOCATED BY TRANSFERING OF CELLS INTO DIFFERENT MEMBRANES
How does a cell regulate location of proteins? Explain 4 specific examples.
4. How does a cell regulate protein activity to impact mechanisms/cell functions? Why is this important? Have five specific examples and do not include any mechanisms that completely degrade the protein of interest.
How does a cell use vesicles to control key cell functions? Have 4 different examples.
give at least 4 examples of viral diseases exemplifying how the surface proteins facilitate gaining entry to target the cell
How does acetylcholine esterase interact with the ECM ... are there specific proteins that are required for its expression? how would you expect the enzyme to be translated/transported to the ECM and which of the ECM proteins interact with the esterase?
Contrast the concepts of 'housekeeping' genes (and proteins) from the cell-specific genes (and proteins) that characterize and define a differentiated cell type. Propose an experiment that would distinguish the tissue-specific gene expression from housekeeping gene expression in muscle cells
1. how do cyclin dependent kinases regulate the cell cycle? 2 how does mitosis work ? 3. draw out each phase of meiosis
How does a cell control the cell cycle? Explain 4 different ways that cell cycle is controlled.
1. How do prokaryotes conserve energy? 2. How do DNA-binding proteins in prokaryotes regulate genes? 3. What is an operon? 4. What is in the lac operon in E. coli? 5. What is the function of the genes in the lac operon of E. coli? 6. What turns the lac operon off? 7. How does a repressor protein turn off the lac operon? 8. How does lactose turn on the lac operon?
1. 2 functions of plasma membrane proteins and explain why the specific functions you listed are important to a cell. 2. List 2 properties of water and describe how they benefit life. 3.Differentiate between a hypothesis, a guess, and a theory. Explain why it is important for non-scientists to understand how scientists use these terms
Explain how DNA methylation could be used to regulate gene expression in a tissue-specific way. When and where would de novo methylation occur, and when would demethylaiton occur? What would occur in the cells that give rise to eggs and sperm (germ-line cells)
