What are the three types of cell signaling

PIT_PIT [208]

Answer:

there are 4: paracrine signaling, autocrine signaling, endocrine signaling, and synaptic signaling

Explanation:

paracrine:cells that are near one another communicate through the release of chemical messengers

autocrine: a cell signals to itself, releasing a ligand that binds to receptors on its own surface

endocrine:When cells need to transmit signals over long distances, they often use the circulatory system as a distribution network for the messages they send.

synaptic: nerve cells transmit signals. The junction between two nerve cells where signal transmission occurs.

Growth hormone and insulin are protein hormones that regulate carbohydrate metabolism by hepatocytes (liver cells) through the a

aleksklad [387]

Answer:

The data from the experiment support the claim that the similar regulation of carbohydrate metabolism by hepatocytes occurs when the cells are treated with growth hormone or insulin results from the activation of different signaling pathways

Explanation:

If we take a look on the graph, it shows increase in the phosphorylated protein when the growth hormone or insulin is applied to the cells with the passage of time. At 15 minutes , it reaches to its highest level but after 15 minutes of addition of growth hormone and insulin, the level of phosphorylated protein decrease when the time exceeds from 15 minutes to 240 minutes. So it is concluded that growth hormones or insulin increase the level of phosphorylated protein.
