Answer ALL questions please. ALL QUESTIONS
1) Protein kinase A (PKA) is a family of enzymes that are part of cell signal systems, and their effect is to phosphorylate proteins, altering their activity. As an example, PKA can phosphorylate the enzyme acetyl- CoA carboxylase, causing it to activate. The ?G for this phosphorylation is +4.2 kcal/mol. How is ATP used to phosphorylate this enzyme, and how does phosphorylation affect enzyme activity?

4. Development of organelles Aa Aa 3 Modern eukaryotic cells are very complex and have many features that allow them to function efficiently. These complexities took a very, very long time to evolve and likely progressed as a series of small improvements that were naturally selected. For example, modern eukaryotic cells have internal membranes surrounding their organelles and the nucleus. This arrangement likely arose when the cellular membranes of some ancient bacterial cells accidentally folded to become internal membranes. Which...
