A mitochondrion has just been engulfed by a cup-shaped isolation membrane as it undergoes mitophagy. Before lysosomal fusion, ho
harkovskaia [24]

Answer:

Option-C

Explanation:

Mitophagy refers to the process which is evolutionarily conserved in the organisms to remove the dysfunctional mitochondria in the cell.

The mitochondrial is degraded by the digestive organelles by engulfing the mitochondria.

The mitochondria are engulfed by the lysosome and then phagosome is formed which is double membrane structure. This phagosome matures into the autophagosome and now has the mitochondria engulfed.

Since the mitochondria contain toe layer and during mitophagy engulfed by the phagosome, therefore, there is a total of four-layer.These four layers separate the matric of the mitochondria with the cytosol.

Thus, Option-C is the correct answer.

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.
