The electrons generated from the krebs cycle are transferred to and then are nad / bonded to oxygen molecules nadh/ combined with hydrogen and oxygen to form water nad / shuttled to the electron transport chain

If cells in the process of dividing are subjected to colchicines, a drug that interferes with the functioning of the spindle fibers, at which stage will mitosis be arrested?

What are the characteristics of living things

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations. for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)
