Answer:

The conversion of glucose to glucose 6‑phosphate;

The formation of fructose 1,6‑bisphosphate from fructose 6‑phosphate;

The formation of pyruvate and ATP from phosphoenolpyruvate and ADP;

The formation of 3‑phosphoglycerate and ATP from 1,3‑bisphosphoglycerate and ADP

Explanation:

All the above mentioned reactions of glycolysis are irreversible. The reason why these are irreversible is because they are involved in either the phosphorylation of the target molecule or removal of the phosphate group from the target molecule. In rest of the reactions of glycolysis either isomerization or rearrangement of carbon atoms is occurring which does not require much energy so the reactions are reversible.

During phosphorylation, phosphate group forms a covalent bond (very strong bond) with the target molecule that is why it requires a lot of energy to break this bond so as to regenerate the reactants again making the reverse reaction impossible.

Reversible reactions on the other hand require weak bonding at the point of interaction so that it could be easier to regenerate the reactants from the product.

The correct term to fill in the blank would be "oprn adoption". An open adoption may involve anything from a minimal exchange of information to extensive contact with the birth mother before and after the child is born. It is a form of adoption wherein the adoptive families and the biological family would have rights to a certain degree of the personal information of the adoption process and having an option of contract. In this type of adoption, the adoptive family would have all the rights to be the legal parents however the biological could have a the right to have a contract in different forms like sending photos of the child, personal visits and sending messages.

Answer:

The nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope.

The red dots are salt. What type of solution is this cell in, and in which direction will

Leto [7]

Answer:

A) hypertonic, out of the cell.

Explanation:

When cells are exposed to high levels of salt (sodium chloride) they lose water by osmosis and shrink. The cytoplasm condenses and the movement of cellular components, such as the cytoskeleton and organelles, stops. Cells adapt to high salt by quickly importing salt in order to attract water and regain volume, at the expense of increased salt concentration. Unlike cell volume, the movements of cellular components are slow to recover and, depending on the dose of salt, may not recover fully.

Marco has experienced extreme fatigue (tiredness) lately. He eats three balanced meals each day and exercises 2-3 times per week

Kisachek [45]

Given the symptoms shown by Marcos, we can infer that the organelle that may be causing his problems is the mitochondria.

The mitochondria are one of the most famous and important organelle within a cell. Found in most eukaryotic cells, they are the organelle responsible for most of the energy production of a cell, and throughout the cells of the body, they become responsible for the energy production of the organism. This is the origin of its famous "Powerhouse of the cell" title. Mitochondria produce energy in the form of ATP.

ATP is a molecular compound necessary for most of the reactions that take place in a cell. It is so common as a requirement for any cellular activity that ATP is known as the "molecular currency". Marcos is said to be experiencing chronic fatigue, which is a symptom of mitochondrial disease. When the mitochondria of an organism's cells are not functioning as they should be, the cells do not have the energy needed to perform basic functions.

In reaction to this, the body sends signals to the brain to go to sleep, which minimizes energy consumption by slowing down the metabolic processes which require ATP and thus gives the body time to produce more energy. For these reasons, we can conclude that the fatigue and problems Marcos is experiencing are due to mitochondrial disease.
