Answer:
A geneticist has devised a strategy to study protein translocation into the endoplasmic reticulum (ER) in yeast cells. She is interested in two different signal sequences that are thought to operate via slightly different translocation mechanisms. Using genetic engineering, she has fused the first signal sequence to a protein whose cytosolic expression is absolutely necessary for cell survival in the selective medium, but is inactive when in the ER. In the same cell, she has also fused the second signal sequence to a toxic protein whose cytosolic expression leads to cell lysis but is harmless when in the ER. Whereas wild-type cells undergo lysis upon the expression of these fusion proteins, she has been able to identify viable mutants, each of which has a loss-of-function mutation in a gene encoding a protein involved in membrane translocation. The products of these genes are probably ...
Explanation:
Involved in the transport of proteins with the first signal sequence but not the second one.
In spherocytosis, there is a defect in the membrane proteins of the red blood cells, specifically ankyrin and spectrin. These membrane proteins contribute to the biconcave shape of red blood cells therefore the loss of these proteins will lead the red blood cells to lose its biconcave shape--leading to abnormally shaped red blood cells (spheres) hence the name. This can lead to premature destruction of red blood cells and jaundice due to hyperbilirubinemia. Spherocytes do not hold oxygen and carbon dioxide well as spherocytes have a decreased surface area.
Answer:
tbh pot roast, prime rib and blade steak are your best options
The products of photosynthesis is to gain energy and build compounds, like glucose from carbon dioxide, making it anabolic
The reactants of cellular respiration are catabolic, and that refers to the breaking down of compounds, which releases energy.
The relationship is that they're complex compounds that consist of materials coming from essential processes in the cell.
