When NADH or NADPH transfers electrons to a recipient molecule, the recipient becomes reduced and the activated carriers are oxi

Allushta [10]

Answer:

NAD is a coenzyme found in all cells. It consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and another that contains nicotinamide.

Explanation:

In metabolism, NAD participates in oxidation reduction reactions. This coenzyme is found in two forms in the cells: NAD and NADH. NAD accepts electrons from other molecules and is reduced, forming NADH, which you can use as a reducing agent to donate electrons. These electron transfer reactions are the main function of the NAD.

In living organisms, NAD can be synthesized from scratch from the amino acids tryptophan or aspartic acid. Some NADs are found in nicotinamide adenine dinucleotide phosphate (NADP), whose chemistry is similar to NAD, although it has different functions in metabolism.

The type of chemoreceptor responsible for our sense of smell is called a(n) ________.

astraxan [27]

Chemoreceptor is a specialized sensory receptor cell, which responds to a chemical substance and generates a biological signal.
The type of chemoreceptor responsible for our sense of smell is called olfactory receptor. It is also known as odorant receptor, these are found in a small patch of tissue high inside the nose. These cells directly connected to the brain.

Which is a phenomenon that can result from directional selection? a. There is an increase in the number of different breeds of d

anzhelika [568]

Answer:

B) There is an increase in the number of giraffes with long necks in areas of Africa where low-growing trees have died

Explanation:

The directional selection is one of the ways of the natural selection in which the natural selection selects or favours the most extreme trait of the species and the extreme trait show higher fitness than the normal or average trait.

In the given question, the case of Giraffe necks shows directional selection as the normal length of the neck is not favoured by the environment but the extreme trait that is long neck is favoured by the environment and the selection shifted to that level.

Thus, Option-B is the correct answer.

ATP and NADH are important energy carriers in the cell.

gulaghasi [49]

Answer:

1. Diffusible through the cytoplasm: BOTH

ATP is a molecule found in the cytoplasm. During the glycolysis process, two molecules of NADH are formed in the cytoplasm and are subsequently transported to the mitochondrial matrix.

2. Can donate hydrogen atoms: NADH

Cytoplasmic nadh transfers hydrogen to oxaloacetate forming malate.

3. Energy stored in bonds between two terminal phosphates: ATP

The bonds between phosphate groups like those of atp are called phosphoanhydride bonds and are used as "high energy" bonds.

4. Contains adenosine ATP

the atp is known as adenosine triphosphate

5. Activates sugars for glycolysis

ATP, by phosphorylating glucose, activates glucose with two phosphate groups (to increase its energy) so that it can be used in other processes when necessary.

6. Two (net) molecules are generated via glycolysis ATP

7. Supplies the electron transport chain nadh

In the electron transport chain each molecule of NADH is converted to 3 of ATP.

8. Hydrolysis can be coupled to biosynthetic reactions

ATP can be hydrolyzed to ADP and Pi by adding water, releasing energy.

9. Can transfer phosphate groups

ATP provides energy by phosphate group transfer

10. Contains nicotinamide ring NADH
