Absorbing outgoing radiation 
zimovet [89]3 years ago
5 0

Clouds can assist as an umbrella, protecting the earth's surface from incoming cosmic transmission which results in an overall cooling effect. To outgoing long wave transmission, however, clouds assimilate the energy, then release it again, but at their moderate temperature such as they emit lower energy than what they have received and hence act like a blanket by absorbing outgoing radiation.

How does a noncompetitive inhibitor decrease the rate of an enzyme reaction?
Wittaler [7]

Answer :B. By changing the shape of the enzyme's active site.

check the attachment

Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the  active site.

On binding, it disrupts the  normal hydrogen bond and hydrophobic   interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and   ACTIVE SITE of the  enzyme (changed it shape).

Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit  for binding with the substrate, therefore  the efficiency  is reduced. No substrate-enzyme complex, and hence no substrate-product  complex for the release of  products, this brings down the turnover rate and eventually

<u>the rate of reaction of the enzyme</u>

Thus, the enzyme function is totally blocked, even in high concentration of the substrate,

B cells interacting with helper t cells are stimulated to differentiate when _____.
madam [21]
There are choices for this question namely:

<span>A) B cells produce IgE antibodies
B) B cells release cytokines
C) cytotoxic T cells present the class II MHC molecule-antigen complex on their surface
D) helper T cells release cytokines

The correct answer is "helper T cells release cytokines". Cytokines are released by helper T cells when B cells attach to them via receptors. These T cells "help" these B cells to differentiate by secreting certain cytokines. When B cells differentiate, they are converted to plasma cells and able to secrete antibodies to the antigen presented to the T cells. </span>
