Answer to Question #71837 in Biology for Talal Abul

Question

1- One aspect of the new science of synthetic biology involves the laboratory design of cells to perform specific functions. Suppose that you wanted to make a protein for use in a drug trial. Design a cell that would build the protein and export it from the cell. (simple drawing including organelles needed to build and export proteins and their function)
2- Because materials move from high concentration to low concentration via simple diffusion, and because they move the same way via facilitated diffusion, why do cells make proteins to carry out facilitated diffusion? Isn’t this just a waste of energy?
3- Where do you expect people would have more mitochondria: their skin cells or their muscle cells? Why?
4- Why do broad, thin leaves provide an advantage for photosynthesis?
