6 Students are using beads of different colors to represent the molecules in food. The beads can be connected in
different arrangements to represent different molecules.
Beads
Chain of beads
What is the best way for the students to use the beads to represent the processes of photosynthesis and
cellular respiration?
Connect all the beads together into the longest chain that can be made.
Combine the beads in chains, take them apart, and then put them together in new chains.
Ο Ο Ο Ο
Take apart all chains and separate the beads by color into groups.
Connect different combinations of beads into chains so that no two are alike.

What are genotypes? what are phenotypes?

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.)
