Which Of The Following Enzyme-Related Claims Is Untrue?

Enzymes are proteins that help speed up metabolic reactions and are typically composed of amino acids. They can be used to catalyze chemical reactions over and over again, and they are usually proteins. However, some statements about enzymes are false, such as the optimal activity of an enzyme occurring within a narrow pH range, the substrate binding to the enzyme with low specificity, the optimal activity of an enzyme occurring within a narrow pH range, or that enzymes are highly specific.

To determine which statement about enzymes is false, we must examine each option one by one. The statement “enzymes are equal active at all” is true, as all living things have enzymes. Enzymes are also known to be reusable, being generally proteins. However, some statements about enzymes are false, such as the substrate binding to the enzyme with low affinity, the optimal activity of an enzyme occurring within a narrow pH range, or that enzymes are highly specific.

The correct answer is option E, which states that most enzymes are proteins, but some are lipids. This statement is incorrect, as most enzymes are much smaller than their substrates. The correct answer is option E, which states that most enzymes are highly specific, increase activation energy, require optimum substrates, supply ATP to their substrates, and may be used many times.

In conclusion, the most important statement about enzymes is that they are proteins that help speed up metabolic reactions and are not specific for any specific substrate. Enzymes are essential for the proper functioning of our bodies and play a crucial role in the overall process of metabolism.

Which one of the following statements about enzymes is not true?

Answer and Explanation: It does not participate in the reaction so it is not consumed and is able to participate in additional reactions. Thus the statement that is not true is A. Enzymes are consumed during the chemical reaction.

What are 5 main facts about enzymes?

Interesting Facts About EnzymesEnzymes are very temperature-specific. … Enzymes play an important role in the digestion of food in our body. … Enzymes are even used in industries such as food processing, paper industries, and detergents. Enzymes are also pH specific. … They are also concentration-specific.

Have you ever wondered about how we get energy by eating food? Where does that food go at the end? Who is responsible for the digestion of the food? Well, the answer to all the above questions is enzymes. Enzymes are present in almost all living organisms and are responsible for many activities like digestion, providing immunity, the functioning of the brain, etc. If our body doesn’t have any enzyme then it will take years to digest the food we eat. Enzymes are secreted by various organs of our body and they are temperature and pH-sensitive. Also, one enzyme does not interfere with the activity of any other enzyme as they are specific in nature. We will learn more facts about enzymes below.

What are Enzymes?. This brings us down to draft a simple definition of what are enzymes. Enzymes are basically proteinaceous in nature which helps in catalyzing biochemical reactions. They have a complex molecular organization and occur in living cells. In 1926 Sumner stated the proteinaceous nature of enzymes. They work by lowering the activation energy of the reaction thus the reactions are completed at a very fast pace.

Which one of the following statements about enzymes is wrong?

Final answer: So, ‘most enzymes are proteins but some are lipids’ this statement is wrong.

What is true about enzymes?

An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over. A cell contains thousands of different types of enzyme molecules, each specific to a particular chemical reaction.

An enzyme is a biological catalyst that is usually a protein but could be RNA. The point of a catalyst is to increase the speed with which a reaction happens. And there are many, many enzymes that are encoded by the genome to make proteins or RNAs that speed up various chemical reactions to do thousands of different functions inside a cell.

Are enzymes specific True or false?

Enzymes are proteins that stabilize the transition state of a chemical reaction, accelerating reaction rates and ensuring the survival of the organism. They are essential for metabolic processes and are classified into six main categories: oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases. These enzymes catalyze specific reactions within their categories, with some being inactive until bound to a cofactor. The cofactor and apoenzyme complex is called a holoenzyme.

Enzymes are proteins composed of amino acids linked together in polypeptide chains. The primary structure of a polypeptide chain determines the three-dimensional structure of the enzyme, including the shape of the active site. The secondary structure describes localized polypeptide chain structures, such as α-helices or β-sheets.

The tertiary structure is the complete three-dimensional fold of a polypeptide chain into a protein subunit, while the quaternary structure describes the three-dimensional arrangement of subunits. The active site is a groove or crevice on an enzyme where a substrate binds to facilitate the catalyzed chemical reaction. Enzymes are typically specific because the conformation of amino acids in the active site stabilizes the specific binding of the substrate. The active site typically occupies a small part of the enzyme and is usually filled with free water when not binding a substrate.

Can enzymes be damaged by high temperature?

• Enzymes are mostly proteins that catalyze various biochemical reactions. The catalytic reaction occurs through a specific region (active site) where the substrate bind.
• Enzymes show the highest activity at a specific temperature called ‘optimum temperature’.
• High heat destroys enzymes. Enzymes are protein molecules that get denatured at high temperatures.
• High heat breaks hydrogen and ionic bonds leading to disruption in enzyme shape. The enzyme loses its activity and can no longer bind to the substrate.
• Certain enzymes synthesized by bacteria and archaea that grow exposed to high temperatures are thermostable. They are active even at temperatures above 80°C and are called hyper thermophilic enzymes. For example- thermophilic lipase is active at a high temperature.

What are true statements about enzymes?

Enzymes increase the rate of a reaction by raising the activation energy for reactions. Enzymes react with their substrate (form chemical bonds), forming an enzyme-substrate complex, which irreversibly alters the enzyme. The more heat that is added to a reaction, the faster the enzymes will function.

What’s wrong with enzymes?

What Problems Can Happen With Enzymes?. Sometimes, the body can be missing an enzyme or have too little of it. This can cause health problems. Medical conditions caused by problems with enzymes include:

• Lactose intolerance : a problem with the enzyme lactase, which causes gas, cramps, and diarrhea
• phenylketonuria (PKU) : a problem with an enzyme that breaks down an amino acid, leading to brain damage and seizures
• Morquio syndrome : an enzyme that breaks down a type of sugar is missing or there isn’t enough of it, leading to vision, hearing, bone, and heart problems
• Tay-Sachs disease : an enzyme is missing, so fatty proteins build up in the brain and lead to damage in the brain and spinal cord
• galactosemia : a problem with the enzymes that break down the sugar galactose, which can lead to trouble growing and gaining weight, and slowed development
• Wilson’s disease: a problem with a liver enzyme, causing copper to build up in the liver, brain, and other organs
• Gilbert’s syndrome: a problem with an enzyme that breaks down bilirubin, which causes jaundice (yellowing of the eyes and skin)

What Are Dietary Enzyme Supplements?. Dietary enzyme supplements are made to mimic what the body’s enzymes do. Doctors may prescribe enzyme supplements for:

• Lactose intolerance to help with gas and diarrhea
• cystic fibrosis to help with digestion

Which of the following statements about enzyme is false?

Final answer: The false statement regarding enzymes is that they alter the equilibrium constant of a reaction. Enzymes do increase the rate of a reaction, lower the activation energy, and act specifically on one or a group of related substrates.

What is a false statement regarding enzymes?

The false statement regarding enzymes is option c: “Enzymes supply ATP to their substrates.” Enzymes are proteins that act as catalysts, meaning they facilitate and speed up metabolic reactions in living organisms.

Which of the following statements about enzyme function is false?

Enzymes must be synthesized for each new chemical reaction. This statement is false because enzymes are not required to be synthesized for each new chemical reaction. Enzymes are proteins that can be reused and are not consumed during the reaction.
