Imagine that you are observing an enzyme-catalyzed reaction in the lab. Every time you add more enzyme, the reaction rate increa

ses proportionally until the reaction rate suddenly levels off. No other chemicals were added, and no modifications were made in the experimental setting. Why do you think the reaction rate stopped increasing?

Answer:

<u>All the substrates are bound to the enzyme</u>, thats why the reaction rate stopped increasing.

Explanation:

Actually an enzyme works by binding a substrate molecule to its active site, producing a product  , resulting in an increase in the rate of reaction.

            Enzyme + substrate = Enzyme + product

Whenever enzymes are added , reaction rate increases as the substrates are being bound to the enzyme's active sites but then occurs a stage where further addition of enzyme cannot increase the reaction rate because all the substrates have bound to the enzyme and <u>there are no substrates left.</u> Hence the reaction rate stopped increasing.

Using the diagram that explain how proteins are formed, check ALL the statements that are true about the structure of proteins.
Snowcat [4.5K]

Answer/Explanation:

If a protein has a quaternary structure it is formed when many subunits get together. - true. The quaternary structure of a protein is the final stage in its assembly, when structures from multiple polypeptides come together, forming a multi-subunit protein (e.g. a dimer if 2, a trimer if 3 and so on)

Monomers form the secondary structure of proteins. - false, they form the tertiary structure

The charges on the functions groups of the amino acids creates the beta pleated sheets and alpha helix structures that are the secondary level of structure in proteins. - false, it is mostly the peptide backbone that causes the alpha helices and beta sheets to form

The order of the amino acids is the primary structure of proteins.  - true. The amino acid sequence linked together by peptide bonds is the polypeptide sequence, which then forms increasingly complex structures when folded.

The tertiary structure of proteins is formed when the B sheets and alpha helices organize themselves into a more complex shape. - true. These complex structures can further interact with one another to form increasingly organized domains. The amino acid side chains possess different properties that form different bonds with one another.

The primary structure of proteins is formed from the amino groups on the proteins.  - false, the primary structure is formed by the sequence of amino acids in the chain, determined by the mRNA sequence from which the protein is synthesised.
