Answer:

Regeneration of ATP is an endergonic reaction and is coupled with an exergonic reaction.

ATP hydrolysis is an exergonic reaction and provides energy for other endergonic reactions.

Explanation:

Phosphorylation of ADP into ATP is an endergonic reaction while ATP hydrolysis into ADP and inorganic phosphate is an exergonic reaction.

The exergonic reactions are the ones that release energy. The released energy can drive the endergonic phosphorylation of ADP into ATP.

The endergonic reactions are the ones that need the input of energy to occur. These reactions are often coupled with ATP hydrolysis as ATP hydrolysis releases energy.

Therefore, endergonic reactions use ATPs while exergonic reactions release energy to regenerate ATPs.

Answer:

The middle carbon atom of pyruvate in the TCA cycle becomes the carboxyl carbon of acetate and hence the newly added (upper) carboxyl group in citrate

Explanation:

Before entering the TCA cycle, pyruvate is converted into Acetyl-CoA by oxidative decarboxylation of pyruvate. 1st two carbons of glucose to be fully oxidized. This reaction is catalyzed by Pyruvate dehydrogenase.

The middle carbon atom of the pyruvate in the TCA cycle becomes the carboxyl carbon of the acetate as the carboxyl group is removed from the pyruvate , releasing CO2. NAD is reduced to NADH. Acetyl group is transferred to coenzyme-A , resulting in acetyl coA

Which of the four levels of protein structure is maintained after denaturing?

Alexxx [7]

Denaturation of proteins includes the interruption and conceivable decimation of both the secondary and tertiary structures. Since denaturation responses are not sufficiently solid to break the peptide bonds, the essential structure (arrangement of amino acids) continues as before after a denaturation procedure.

Which biomolecule do living organisms use as energy storage?

Norma-Jean [14]

Answer:

Fats are the primary long-term energy storage molecules of the body. Fats are very compact and light weight, so they are an efficient way to store excess energy. A fat is made up of a glycerol, which is attached to 1 to 3 fatty acid chains.

1) Why does the addition of dideoxynucleotides to the DNA sequencing reaction cause DNA synthesis to stop after the modified nuc

lisov135 [29]

In Sanger sequencing, once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added. This phenomenon is useful to sequence a polynucleotide chain.

Dideoxynucleotides (ddNTPs) are nucleotide inhibitors of the DNA polymerase, it is for that reason that they are used in Sanger sequencing.

The ddNTPs are similar to natural deoxynucleotides used by cells during ADN replication; however, ddNTPs lack a hydroxyl (OH) group on the 3’ carbon of the deoxyribose.

In consequence, once a ddNTP is added, DNA synthesis cannot progress, thereby this phenomenon can be used to determine the order of nucleotides during the elongation of a polynucleotide DNA chain.
