Protein A and Protein B work together to import iron into a living cell. Proteins A and B are both integral membrane proteins that are capable of binding one another and together they reduce Fe (III) to Fe (II) and then import Fe(II) from outside to inside the cell. It has been found that mutations in the gene encoding spectrin can reduce the amount of iron that is imported into the cell. Create a hypothesis to explain this observation

Previous experiments with the Cdc16 and Cdc23 mutants suggested that the encoded proteins work together to execute common functions. Investigators hypothesized that they exist in a protein complex. You decided to use yeast two hybrid assay to show that these two proteins interact. Explain in your own words how you would do this.

The endomembrane system is a collection of cell structures that work together. Each of the following are part of the endomembrane system: cell membrane, nucleus, ribosomes, endoplasmic reticulum, and golgi bodies. Explain how each of these cell structures are related to each other in function. In other words, briefly describe the central dogma of Biology. (Hint: your answer should be all about proteins!!) Briefly describe the overall process of cellular respiration. Please DO NOT discuss specific stages of the process...
