The third phosphodiester bond of ATP is broken mostly. The rest of the molecule is called Adenosine Diphosphate or ADP.
<h3><u>Explanation:</u></h3>
For knowing the answer, we need to know the structure of ATP first. ATP or the Adenosine Triphosphate is also called the energy currency of living cell. It has two components -
A. Adenosine which is actually an Adenine nitrogen base attached with a ribose sugar molecule.
B. Phosphate molecules.
The structure of Adenosine Triphosphate is a ribose sugar which is attached with one adenine molecule with which one phosphate ion is attached and the rest of the phosphate ions are attached with the phosphate one after the other.
Ribose - Adenine - Phosphate - Phosphate ~ Phosphate.
The last phosphodiester bond between the two phosphates is the most energetic bond containing maximum of the energy. This bond is broken during the metabolic processes to supply energy to the processes.
Answer:
How the sea serves us
> Many of the ecosystem services provided by the sea are threatened today by overexploitation, environmental pollution and greenhouse gases. Yet in many cases, how severely individual habitats are degraded and ecosystem services are impaired is just not known. Researchers are therefore attempting to assess the exact condition of marine ecosystems. Such analysis is important in order to plan concrete protection measures and to define critical limits and target values.

The bounty of the sea
> Since time immemorial we humans have been living with the seas and from their bounty. They provide us with food, mineral resources, transportation routes and other services. The climate-regulating effect of the oceans and the biochemical processes that take place in the sea are of fundamental importance. Today, some of these services are under threat, which i
Answer: There will be a number of 25600 bacteria after 2 hours.
Explanation: This problem requires some simple math to solve.
We were told that E. coli doubles approximately every 15 minutes. Meaning that, after just 15 minutes, our colony of 100 bacteria is now a colony of 200 bacteria and so forth:
100 * 2^1 = 200
There are 4 15-minute periods in an hour, thus there are 8 15-minute periods in two hours. Therefore, the bacteria will have doubled their population size 8 times:
100 * 2^8 = 25,600
