Answer:

Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis

Explanation:

Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.

Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.

pickupchik [31]

Answer:

1)required for cellular respiration(Oxygen only)

2) net diffusion from alveoli to lung capillaries(Oxygen only)

3)sometimes transported as bicarbonate(Carbon Dioxide Only)

4)net diffusion from body tissues to blood(Carbon Dioxide Only)

5)net diffusion from lung capillaries to alveoli(Carbon Dioxide Only)

6)waste product of cellular respiration(Carbon Dioxide Only)

7)enters alveoli during inhalation(Both Oxygen and carbon dioxide)

8)transported by hemoglobin(Both Oxygen and carbon dioxide)

Explanation:

Gas exchange is a mechanism that helps the body to get the necessary Oxygen that is required for cellular respiration to take place

There is diffusion of oxygen to capillaries that are present in the lungs from the alveoli.

Gas exchange is a mechanism that is also responsible for the body to get rid of waste such as carbon dioxide,

amid [387]

Smooth muscle fibers can sustain a contraction without fatigue by allowing dephosphorylated myosin to remain attached to actin in what is called the <u>Latch State</u>.

Latch State- Myosin cross-bridge creation with actin is prevented by dephosphorylating its RLCs, however dephosphorylating myosin that is already attached to actin slows down its off rate, creating the so-called "latch state." In the latch state, smooth muscle maintains tension while undergoing modest rates of ATP hydrolysis.

ATP hydrolysis- When the high-energy phosphoanhydride bonds in adenosine triphosphate are split, as occurs, for example, in muscles, chemical energy that has been stored in them is released. This process is known as ATP hydrolysis.
