Answer of Which of the following statements about enzymes is incorrect. 1 The catalytic action of an enzyme is not specific 2 An enzymatic reaction is highly sensitive to temperature 3 The catalytic action of enzymes is due to their capacity to lower the energy of activation of a particular reaction 4 None of the above Biomolecules Chemistry Questions Practice questions MCQs.

Their specificity is due to the shape of the active site. Succinylcholine is structurally almost identical to acetylcholine. Most of the enzymes have proteinous nature.

At optimum temperature which is generally in between enzyme activity is maximum. Enzymes are least reactive at optimum temperature. Following Statements Describe The Characteristics Of The Enzyme Restriction Endonuclease.

When the concentration of substrate is low the rate of an enzyme-catalyzed reaction increases with the concentration of the substrate. 2 The enzyme binds DNA at specific sites and cuts only one of the two strands. Enzymes serve as a biological catalyst by accelerating the rate of chemical reaction occurring inside the cells.

Enzymes are least reactive at optimum temperature. Allosteric enzymes have two states one that has low activity and one that has high activity b. E Enzymes undergo a permanent change during the.

1 Enzymes may increase the rate of a reaction by 105-1017 fold. They are highly specific for their DNA target sequences. Most of the enzymes have proteinous nature.

Which one of the following statements is incorrect about enzyme catalysis. B For every protein there is a gene. Enzymes are proteins that are made using a combination of a large number of amino acids.

Which of the following statements about enzymes is incorrect. At optimum temperature 25 to 35 C enzyme activity is maximum. B Enzymes speed up chemical reactions.

Enzyme action is specific. Which of the following statements is INCORRECT with respect to allosteric enzymes. Enzymes are inorganic catalyst.

Enzymes are colloidal in nature. They are highly specific and get denaturated by high temperature or UV-rays. They come in many varieties each with its own DNA target sequence.

If succinylcholine is added to a mixture that contains acetylcholine and the enzyme that hydrolyzes acetylcholine but not succinylcholine the rate of acetylcholine hydrolysis is decreased. Coenzymes assist is activating their function. B Enzymes speed up chemical reactions.

Which of the following statements about enzymes is incorrect. B Enzymes speed up chemical reactions. D Enzymes contain an active site for binding of particular substrates.

5 Some enzymes are comprised of RNA instead of protein. Enzymes are mostly proteinous in nature. C Enzymes often induce conformational changes in the substrates that they bind.

E Enzymes undergo a permanent change during the. Enzyme action is specific. Which of the following statement is incorrect.

B Ligases are the enzymes used to glue DNA fragments. When the concentration of the substrate is low the reaction depends only on the concentration of the enzyme. Enzymes are least reactive at optimum temperature.

Which of the following statements is INCORRECT. D For every molecule of fat there is a gene - Get the answer to this question and access a vast question bank that is tailored for students. Which of the following statements about enzymes is incorrect.

Competitive inhibition involves a molecule binding to the enzymes active site. 1 The catalytic action of an enzyme is not specific 2 An enzymatic reaction is highly sensitive to temperature 3 The catalytic action of enzymes is due to their capacity to lower the energy of activation of a particular reaction 4 None of the above Biomolecules Chemistry 2021 Practice questions MCQs Past. A b c Most metabolism occurs hepatically and is carried out by enzymes Most excretion occurs renally At steady state the administration rate and the distribution rate are equal Clearance is a pharmacokinetic parameter measuring metabolism and excretion The half-life of a drug is a useful measure to.

Which following statement about enzymes is incorrect. Identify The Incorrect Statement. Thus they are of a giant size and exhibit a lower diffusion rate which is the reason behind its colloidal nature.
