Answer:
The correct answer is - option e. uses ATP as a substrate.
Explanation:
Poly-A Polymerase is an enzyme of the family of the DNA polymerase beta (polβ) family which catalyzes the reaction of the addition of AMP from ATP to the DNA polymerase beta (polβ) family.
ATP+RNA-3'OH--------->Pyrophosphate + RNApA-3'OH.
In this reaction, after the mRNA is cleaved, the Poly-A Polymerase template-independently adds about 200 A nucleotides (from ATP) one by one.

See the answer below
Explanation:
Enzymes are biological catalysts and are quite temperature specific. They operate optimally within a certain range of temperature. At lower temperatures, their activities decrease and they become inactive at extremely low temperatures. At higher temperatures, their activities are initially promoted but as temperatures get higher, their activities become zero due to the fact that they become denatured.
A. <em>The optimum temperature for amylase activity is 37</em>
<em>, hence, when the student had the first test tube at this temperature, the rate of reaction of the enzyme is optimal. The maximum amount of starch would be broken down into maltose.</em>
B.<em> At 0 degrees, the enzyme would become inactive and the rate of reaction becomes minimal or even zero due to the inactivity of the enzyme. At 60 degrees, the rate of reaction also becomes zero because the enzyme would have been denatured by the high temperature.</em>
Answer:
Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Since the beginning of the Industrial Revolution, people have burned more and more fossil fuels and changed vast areas of land from forests to farmland.
Explanation:
Answer:
protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge.
A.) radiant Cause yk the sun!
