What two parts of a nucleotide do not change throughout the structure of DNA?

Answers

Answer:

The second portion of the nucleotide is the sugar. Regardless of the nucleotide, the sugar is always the same. The difference is between DNA and RNA.

Explanation:

thanks me and follow me

Five-carbon sugar (deoxyribose sugar) and phosphate moiety are the two parts of a nucleotide which do not change throughout the structure of DNA.

What are Nucleotides?

Nucleotides are the organic molecules which are consisting of a nucleoside molecule and a phosphate moiety. They serve as the monomeric units of the nucleic acid polymers- deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all the different life-forms on the Earth.

Nucleosides are made up of nitrogenous bases and pentose sugar. There are changes at the nitrogenous bases in the different nucleoside molecules however, there are no changes in the pentose sugar and the phosphate moiety of the molecule.

Is ATP used for long term storage?

Answers

Answer:

Explanation:

ATP is not used for long term storage.

ATP will release or give off energy when it releases a phosphate molecule. Since a cell can add or subtract a phosphate group, it has a way of storing and releasing energy. Most cells have only a small amount of ATP. It can't be used to store energy for long periods of time. These ATP stores last only a few seconds after which the breakdown of PC provides energy for another 5-8 seconds of activity. Combined, the ATP-PC system can sustain all-out exercise for up to 10-15 seconds and it is during this time that the potential rate for power output is at its greatest. These ATP stores last only a few seconds after which the breakdown of PC provides energy for another 5-8 seconds of activity. Combined, the ATP-PC system can sustain all-out exercise for up to 10-15 seconds and it is during this time that the potential rate for power output is at its greatest. Hence, ATP cannot be stored easily within cells, and the storage of carbon sources for ATP production (such as triglycerides or glycogen) is the best choice for energy maintenance. Lipids are molecules that can be used for long-term energy storage. Most cells have only a small amount of ATP. It can't be used to store energy for long periods of time. It is more efficient for a cell to keep a small supply of ATP. Cells can regenerate ATP from ADP as needed by using the energy in carbohydrates like glucose. The ATP molecule is just like a rechargeable battery. When it's fully charged, it's ATP. When it's run down, it's ADP. However, the battery doesn't get thrown away when it's run down–it just gets charged up again. Living organisms use two major types of energy storage. Energy-rich molecules such as glycogen and triglycerides store energy in the form of covalent chemical bonds. Cells synthesize such molecules and store them for later release of the energy. Monosaccharides
Monosaccharides contain just one sugar unit, so they're the smallest of the carbohydrates. (The prefix "mono-" means "one.") The small size of monosaccharides gives them a special role in digestion and metabolism. In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

True or False: Enzymes have an optimal or ideal pH level?

Answers

Answer:

All enzymes have an ideal pH value, which is called optimal pH. Under the optimum pH conditions, each enzyme showed the maximum activity. For example, the optimum pH of an enzyme that works in the acidic environment of the human stomach is lower than that of an enzyme that works in a neutral environment of human blood. All enzymes have an optimum pH that they work best at. Its often neutral pH 7, but not always.

What is a function of the respiratory system?

Answers

Answer:

The respiratory system's main purpose is to move fresh air into your body and moving waste gasses out (like carbon dioxide when you breathe out)

The function of the respiratory system is to inhale oxygen which is absorbed by red blood cells in the lungs. The RBC then go to the heart which pumps the oxygenated blood to the rest of the body and non oxygenated blood goes back to lungs to be oxygenated. They also carry back waste such as carbon dioxide to the lungs to be exhaled.

How do i know if its entering or leaving or neither just by the precentage?

Answers

Answer:

1. Shrink

2. Swell

3. Neither

Explanation:

The percentage of water indicates how pure the water is, i.e. how concentrated the molecules of water are.

The higher the percentage of water, the more water molecules there are in the space.

Water molecules move from a high concentration to a low concentration across a semi permeable membrane, by the process of osmosis.

In beaker 1, the water outside is 89%, and inside the bag is 92%. That means the water inside the bag is at a higher concentration than outside. That means water will leave the bag, moving from a high concentration to a lower concentration outside. The bag will shrink.

In beaker 2, the water outside is 97%, and inside is 92£%. That means the water inside the bag is a lower concentration than outside. That means water will enter the bag, moving from a higher concentration outside to a lower concentration outside. The bag will swell.

In beaker 3, the concentration of water inside and outside is the same. That means they are in an equilibrium (the movement is balanced) so neither will occur
