It is mRNA because RNA, which stands for ribonucleic acid, is a polymeric molecule made up of one or more nucleotides. ... During the process known as transcription, a RNA copy of a segment of DNA, or messenger RNA (mRNA), is made. This strand of RNA can then be read by a ribosome to form a protein.
The correct answer is: Decrease allosteric effects and cooperative binding of second messengers to their targets.
Scaffold proteins are considered regulatory proteins that affect many signal pathways. Some of their functions are:
• Regulation and coordination of positive and negative feedback signals
• Localizing signal components within the cell (in different cell compartments)
• Tethering signaling components (assembling signal components into complexes in order to increase signal efficiency).
Because bile contains salts and digestive compounds and lipase is a digestive enzyme, you might create a simple qualitative experiment to test the action of bile and lipase. Bile is first used to emulsify and break down food entering the small intestine, and lipase is used afterwards by the pancreas to break down fats. With this information, I suggest this experiment:
1) Label 4 test tubes A, B, C, and D. Divide the fat solution equally into the 4 tubes.
2) In tube B, add an x amount (but not the whole volume) of the bile solution.
3) in tube C, add a y amount (but not the whole volume) of lipase solution.
4) in tube D, add the x amount of bile and the y amount of lipase solution.
5) Swirl/mix until everything looks homogenized/settled.
6) tube A is your control. Compare the 3 other tubes to it and write observations. You should be able to make conclusions about the role of bile in digesting a fatty solution, and the extent of digestion with and without the additional lipase.
Hope this is helpful!~ There are certainly many other possible experiments.
Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.
The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO3−) and H+. The H+ ion binds to hemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. This is called the chloride shift.
Bicarbonate leaves the red blood cells and enters the blood plasma. In the lungs, bicarbonate is transported back into the red blood cells in exchange for chloride. The H+ dissociates from hemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which further catalyzes the reaction to convert carbonic acid back into carbon dioxide and water. The carbon dioxide is then expelled from the lungs.
The mixed number for the given picture is 1 1/4, the correct option is A.
<h3>What are mixed numbers?</h3>
A mixed number is one that manages to combine a whole number and an appropriate fraction.
To transform mixed numbers to improper fractions, follow these three steps: Multiply the numerator by the whole number.
- Step 1 is to the numerator, add the answer from.
- Step 2 is adding the numerator to the product got from step 1.
- Step 3 is writing the improper fraction with the sum got from step 2 in the numerator/denominator form.
In the given picture, there is one box completely filled and one forth portion in second block is filled, so it is representing mixed number i.e., 1 1/4.
Thus, the correct option is A.
