2. In the citric acid cycle, malate is oxidized to oxaloacetate by the enzyme malate dehydrogenase, which uses NAD+ as an electr

on acceptor. In cells, the ratio of [NAD+]/[NADH] is kept very high. Given the following standard reduction potentials, explain why it is so important for cells to maintain this ratio. Justify your answer with words, equations and diagrams.

Answer:

NAD+ act both as coenzyme as well as electron acceptor compound and get reduced to NADH by accepting electron.

Explanation:

NAD+ act as co enzyme of various biological catalyst such as malate dehydrogenase, isocitrate dehydrogenase etc.

             NAD+ can act as co enzyme only in its oxidized form but not in its reduced form called NADH.

         Many reaction needs NAD+ to occur such as conversion of glyceraldehyde 3 phosphate to 1,3 bisphosphoglycerate, malate to oxaloacetate.

              That"s why NAD+/NADH ratio is kept very high because if this ratio bychance get  low then it will hamper the normal redox potential of NAD+/NADH.As a result many biochemical reaction will not take place.

What functions do plants,animals,and cells have in common
ivann1987 [24]

They are more similar then different. Animal and plant cells have some of the same cell components in common including a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, peroxisomes, cytoskeleton, and cell (plasma) membrane. The main difference is that plant cells have a cell wall while animal cells only have a cell membrane. In addition, plant cells preform photosynthesis, while animal cells preform cellular respiration.

Hope this helps!

The nurse is auscultating for abdominal bruits. which vessel would the nurse auscultate last?
klemol [59]

The nurse is auscultating for abdominal bruits, on carotid artery the nurse auscultate last.

The bruits are a swishing sounds due to turbulence in the blood vessel in the abdomen and it heard due to atherosclerotic changes in the abdomen, whereas the carotid artery may be auscultating for bruits.

The auscultate abdominal bruits are present initially, at the right lower quadrant, it move in the sequence up to right upper quadrant, then to left upper quadrant and then finally to the lower quadrant. The auscultating for bruits are present over the aorta, renal arteries, femoral arteries and iliac arteries.

A species of fly has two alleles for the length of their legs. The allele for long
Artyom0805 [142]
The answer is A. 0.54.

In a population p+q=1 (we have 2 alleles only).

The question states that 0.21 of the population(21%) have short legs meaning they are q^2.

So q=rad0.21=0.4582.

And p=1-q=0.5417.
