Imagine that you have engineered a set of genes, each encoding a protein with a pair of conflicting signal sequences that specify different compartments. If the genes were expressed in a cell, predict which signal would win out for the following combinations. Explain your reasoning. A) Signals for import into […]

Vitamin D was added to reaction vessels at different concentrations containing its receptor protein (at a fixed concentration). After equilibrium was reached, the amount of Vitamin D bound to the protein was determined.

1. Compare contrast the composition of blood plasma and glomerular filtrate. 2. Explain the mechanism of tubular secretion, and explain it’s importance in the urine formation process. 3. Explain why the glomerulus is such a high-pressure capillary bed. How does its high pressure condition aid its function of filtrate formation […]
