How does insulin bind to cells and the mechanism involved in triggering the cells to take in glucose
Lera25 [3.4K]

Explanation:

Once blood glucose levels increase, pancreatic insulin migrates into a fat cell via the blood stream. Insulin then binds in the plasma membrane of the cell to an Insulin Receptor (IR). Through autophosphorylation, phosphate groups are then added to the IR,  causing GLUT4 molecules to come to the cell's surface.

How many 20.0-g ice cubes are required to absorb 47.0 kJ from a glass of water upon melting?
Sati [7]

Hello!


The number of 20-g ice cubes required to absorb 47 kJ from a glass of water upon melting is 7 icecubes


Why?


We are going to clear from the equation of the released heat, the mass of ice (m). The specific latent heat of fusion of ice is 336 kJ/kg:


Q=m*L\\ \\ m=\frac{Q}{L}=\frac{47 kJ}{336 kJ/kg}=0,1399 kg=139,88 g\\   \\ 139,88g*\frac{1 icecube}{20g}=6,99=7icecubes


So, 7 ice cubes are required to absorb that amount of heat from the glass of water.


Have a nice day!

During normal, relaxed respiration, about 500ml of air enters and leaves the lungs with each respiratory cycle. this is called t
Marianna [84]

During normal respiration, about 500ml of air enters and leaves the lungs with each respiratory cycle. This is called the<u> tidal volume</u>.

When a person is relaxed, the normal amount of air such a person breathes in and out is called the tidal volume. It is usually measured in millimeters. For the average adult male, it is 500ml, and the tidal volume of average adult female 400ml.

In order to regulate oxygen intake and expulsion of carbon dioxide, the lungs act as buffers in order to absorb the maximum amount of oxygen possible for respiration and other metabolic functions in the body.

When the tidal volume is above or below the 500ml mark, it could signal the presence of underlying pathological conditions like bronchitis, emphysema and asthma.
