ATP has three phosphate groups that are attached to adenosine. The first phosphate group is attached to adenosine by a phosphoester bond. The second and third phosphate groups are attached to adenosine by different kind of bond known as phosphoanhydride bonds and all these are covalent bonds.
When phosphoanhydride bonds are broken, a greater amount of energy is released than when the phosphoester bond is broken. Therefore in energy production, it is the 2nd or 3rd phosphate group with the higher energy yielding bond that is "unhooked" from ATP to form ADP, yielding a high amount of free energy of at least 7.3 kcal/mol.
Answer:
<h2><u>Their typical prey items include shorebirds, ducks, grebes, gulls, pigeons, and songbirds. Peregrine falcons also eat bats, and they occasionally steal prey—including fish and rodents—from other raptors. Falcons nest on cliffs up to 1,300 feet high and sometimes higher.</u></h2><h2><u>
Explanation:</u></h2>
<h2>Answer:</h2>
steps involved in protein synthesis:
- DNA is transcribed.
- RNA is modified into mRNA.
- A ribosome binds to mRNA.
- Amino acids are lined up in a sequence.
- Chemical bonds are formed and a protein is produced.
<h3>Explanation:</h3>
The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cell's nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins.
Answer:
selective permeability
Explanation:
The cellular membrane is selectively permeable which means it allows the movement of little essential substance from outside and movement of non-essential substances from inside. Along with this several neural activities are controlled through this property of cell membrane that allows to and fro. Movement of specific kind of ions.
It does not allow movement of all substance, particles and ions through it and hence they are selective.
