Step by step
Solved in 2 steps
- What might happen to a cell if there are no steroids in its membrane?Some antimicrobial drugs used to treat bacterial infections disrupt the process of protein synthesis. What could these drugs target? Why would this ultimately lead to cell death?Why would doctors not want to just completely inhibit β-secretase in a patient with Alzheimer’s disease?
- Cytochrome c is part of the respiratory chain in most cells. How can cytochrome c be a signal to induce (start) apoptosis if it already exists in most cells?A drug that inhibits the kinase activity of AKT would MOST likely have which of the following effects? A. Increased GSK-3b activity and increased CyclinD synthesis B. Increased GSK-3b activity and decreased CyclinD synthesis C. Decreased GSK-3b activity and increased CyclinD synthesis D.
