Answer:
c. break the N2 triple bond.
Explanation:
In the general nitrogen reduction reaction (which occurs in the nitrogenase complex), ferredoxin acts as an electron donor to Fe-protein, which in turn hydrolyzes ATP and reduces MoFe-protein. By reducing MoFe-protein one can then reduce numerous (triple bonded) substrates although, under natural conditions, it reacts only to N2 and H +.
That is, ATP must be present in the reaction so that MoFe-protein can break the triple bond N2.
The binding and hydrolysis of ATP to Fe-protein causes a change in conformation of this protein which facilitates redox reactions. The enzymatic reduction of N2 by nitrogenase requires a large energy investment, although the exact changes in free energy are still unknown.
Answer:
If you are referring to the image below, the answers would be:
Monosaccharides:
- Galactose
- Glucose
- Ribose
- Deoxyribose
- Glyceraldehyde
- Fructose
Disaccharides:
Storage Polysaccharides:
Structural Polysaccharides:
Explanation:
Monosaccharides are simple sugars, typically having 3 to 7 carbons in its structures. Aldoses and ketoses are forms of monosaccharides. If a monosaccharide has a aldehyde, it is an aldose. If a monosaccharide has a ketone, it is a ketose. You also have other forms, depending on te number of carbons. (e.g. Tioses, hexose and pentose)
Disaccharides are two monosaccharides bonded covalently through a glcosidc bond. They form through a condensation reaction, specifically through dehydration synthesis. Thus, the name "di" saccharides.
Polysaccharides are complex carbohydrates that are made up of many monosaccharides. Their functions are mainly storage and make up the structure of tissues.
Storage polysaccharides are polysaccharides that act as food reserves or energy reserves. They are called storage because they are stored away for later use. Starch is a storage polysaccharide that is found in plants and glycogen on the other hand, is found in animals.
Structural polysaccharides help form the structures of cell walls in plants and skeletons in animals. The most common ones are chitin and cellulose.
Answer:
None of the given options is correct. The correct solution is "Sprained ankle".
Explanation:
- Brain activation is assessed by functional MRI via identifying causes an increase in blood flow. The assumption that brain blood flow and neural activity are linked is the basis of this methodology.
- MRI allows excellent visualization of the structure of the ankle, allowing ligament defects and their related osteochondral including tendon disorders to be correctly identified. In patients with such an uncertain psychiatric history although with equivocal otherwise complicated psychiatric exams, MRI can be particularly useful for early diagnosis of syndesmotic lesions.
All those other alternatives are not linked to a working MRI. Then the option above is appropriate.
