What is the role of cyclin-dependent kinases in the cell cycle?

Biology
1 answer:
jasenka [17]3 years ago
3 0

Answer:

They initiate various stages of the cell cycle.

Explanation:

Cyclins and cyclin-dependent protein kinases function to control  the cell cycle. A group of cyclins: the G1 cyclins, are synthesized during G1 phase and function  to activate CDPKs which initiate DNA synthesis at the G1/S checkpoint. The cell fails to  progress to S phase if there is no sufficient synthesis of G1 cyclins. After a cell passes through  this point, the G1 cyclins are degraded, allowing for another group of cyclins: the M cyclins  to be synthesized. M cyclins activate a second group of CDPKs which allow  the cell to pass the G2/M control point and into mitosis.

In the glomerulus, a tuft of capillaries in the renal cortex, blood is filtered through the porous capillary walls.
<span><span>
The glomerulus receives its blood supply  (that need to be filtered) from an afferent arteriole of the renal arterial circulation and the glomerular capillaries exit into efferent arterioles. The glomerular filtration rate is a rate at which blood is filtered through all of the glomeruli.</span> </span>

Temperature inversions occur naturally in the stratosphere and thermosphere, but also occur closer to the surface of earth in th
skelet666 [1.2K]

Temperature inversion or thermal inversion is a phenomenon during which the temperature increase when there is an increase in the altitude. It is an uncommon process that happens in the troposphere-the layer of atmosphere closest to the earth.  

When there is an increase in temperature with altitude that warm air acts as a blockage for the cool air near the surface of the earth. So this is just opposite to the normal behavior of the air, where it becomes cooler with an increase in altitude.

So how air circulation behaves during inversion?

So as we said that the cool air nearer to the earth will be blocked by a layer of warm air. This blockage will hinder the circulation of air upwards from the lower layers. Let’s see how:

• As we know that, warm air is less dense and more buyout than cool air and normally less dense warm air is close to the earth and cool air is in above layers. But when the process is reversed, this warm air acts like a blanket for the proper circulation of air. Due to this, many environmental pollutants which normally leave the earth during air circulation get trapped in our air.  

• The trapped environmental pollutants like nitrogen oxides and hydrocarbons get convert into harmful ozone that ultimately deteriorates the quality of air and causes problems like smog.

• The improper air circulation also causes suspension of the harmful gases near the earth instead of allowing them to leave the earth atmosphere. This ultimately causes air pollution.  

• When smoke will not rise, carbon dioxide will be build up in the atmosphere; this will cause greenhouse effect and global warming.

Therefore, air circulation behaves very different during temperature inversion process and poses hazardous effects on global climate.

Hope it helps! :)
