D)calcium-dependent protein phosphorylases
E)protein kinase A

Question

Quizplus · Accepted Answer

Hedgehog is a signalling protein that is specifically associated with development in animals. It plays important roles in cell differentiation, tissue patterning, and organogenesis during embryonic development. In particular, the Hedgehog signalling pathway is crucial for the development of many different tissues, including the central nervous system, limbs, and skin. The other choices listed here are not specifically associated with development in animals. Zbtb7 is a transcription factor that is important for immune function, Ryanodine is a calcium channel receptor that is found in muscle cells, calcium-dependent protein phosphorylases are enzymes that catalyze the transfer of phosphate groups from ATP to target proteins in a calcium-dependent manner, and Protein kinase A is an enzyme that phosphorylates target proteins in response to cAMP signalling. While some of these proteins may be involved in developmental processes, they are not specifically associated with development in animals in the way that Hedgehog is.
