Explanation:

Answer:

I would go with A maybe,am not really sure though.

Answer:

The answer is ATP, ADP

Explanation:

When protein is hydrolyzed, it forms amino acids. Thus, the correct option is A.

Hydrolysis may be defined as a chemical process that utilizes the molecules of water that involve the chemical breakdown of a compound.

Amino acids are the monomers of protein. These amino acids are linked together by peptide bonds. But the process of hydrolysis breaks the peptide bond between the amino acid sequences and released them significantly in free form.

Therefore, when protein is hydrolyzed, it forms amino acids. Thus, the correct option is A.

Answer:

PEP carboxykinase

Explanation:

PEP carboxykinase is also known as Phosphoenolpyruvate carboxykinase. It is an enzyme which is used for the production of glucose from non-carbohydrate carbon substrates. This enzyme is used only in gluconeogenesis not in glycolysis because this enzyme helps in the production of glucose while glycolysis is a process in which the glucose  break down into pyruvate and ATP molecules.

Answer:

Using a graduated cylinder.

Answer:

During Enzymatic reaction, enzymes binds to a substrate to form a which then forms the product.

Change in shape of substrate, product and enzymes depends on the temperature outside the optimal range which affect bonding between enzyme and substrate. Enzymes definitely changes their size when bind to substrat and the process is called induced fit which increases the rate of reaction.

During an enzymatic reaction, their is an decrease in the concentration of substrate, an increase in the concentration of product, and no change in the concentration of the enzyme.

A reaction, which is mediated with the help of an enzyme is termed as enzymatic reaction. A substance, which functions as a catalyst in living organisms and regulate the rate at which the chemical reactions takes place is known as an enzyme.

The enzymatic reactions follows the lock and key model, in which the free enzyme combines with the substrate and forms the enzyme-substrate complex, this is further catalyzed into the enzyme-product complex, from which the free enzyme and product get discharged. The product never further binds with the free enzyme.

In the reaction, the substrate get used up thus its concentration decreases, while the formation of product takes place thus its concentration increases. However, there is no change in the concentration of the enzyme as it does not get used up in the process.

Thus, in enzymatic reaction, substrate decreases, product increases, and enzyme concentration remains the same.

Answer:

Pyruvate helps in the production of ATP.

Explanation:

The molecule of pyruvate converted into acetyl CoA. Then each molecule which is produced during glycolysis loses electron and carbondioxide releases. After the breakdown of pyruvate, the electrons loses by pyruvate are transferred to NAD+ in order to produce NADH, which will be used by the cell to produce energy molecule such as ATP. So we can say that pyruvate plays a vital role in the formation of ATP molecule.

Explanation:

Answer:

start codon - AUG

in-sequence amino acid - AAA, UGC, AUC, CAC, GCA, ACU

stop codon - UAA, UAG, UGA

Explanation:

From the amino acid chart, the start codon is represented by the codon AUG which also code for the amino acid methionine. There are three stop codons including UAA, UAG, and UGA. The stop codons signal the end of the translation process of the mRNA. Every other codon within the mRNA chain codes for different amino acids except methionine.
