Answer:
Right pulmonary artery
Explanation:
Based on the scenario being described within the question it can be said that the structure being described is known as the Right pulmonary artery. This is the longer and also the larger of the two arteries that conveys venous blood from the heart to the lungs. This artery is roughly 3 cm in diameter and 5 cm in length, and it's main function is delivering oxygen-depleted blood to it's corresponding lung.
To complete the statement above:
Ions are transported across membranes using channel-mediated facilitated diffusion; which requires <span>kinetic energy.
The channels can be opened by the requirements of the cell. Transmembrane proteins, called transporters, utilize the vitality of ATP to drive particles or little atoms through the layer against their focus angle.

Answer:
a. Normally, PK2 activates PK1. We are told that PK1 and PK2 normally work sequentially in an intracellular signaling pathway. If PK1 is permanently activated, a response is seen independently of whether or not PK2 is present. If PK1 activated PK2, no response should be seen if PK1 were activated in the absence of PK2.
GSK-3 is an unusual protein kinase in that it displays high, “constitutive” activity in unstimulated cells and is rapidly inactivated upon a variety of cellular stimulations. The most thoroughly documented pathway for the inactivation of GSK-3 is in response to insulin and is mediated by protein kinase B (PKB, also termed Akt), which lies upstream of GSK-3 [8].
The cell membrane of cells present in tubeworm is selectively permeable and they prevent minerals in the water from flowing it in the cell of tube worms. By doing this the cell membrane protects the cell from any osmotic damage. By selectively preventing these minerals it maintains the stable environment in the cell.
