Review Properties of Enzymes 11/13/23

What is the function of enzymes?

• Enzymes function as energy storage in the body.

• Enzymes function as sensory receptors in the body.

• Enzymes function as biological catalysts, speeding up chemical reactions in the body.

• Enzymes function as structural support in the body.

How do enzymes speed up chemical reactions?

• Enzymes speed up chemical reactions by changing the temperature of the reaction.

• Enzymes speed up chemical reactions by increasing the activation energy required for the reaction to occur.

• Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.

• Enzymes speed up chemical reactions by decreasing the concentration of reactants.

What is the active site of an enzyme?

• The active site of an enzyme is the location where the enzyme is produced.

• The active site of an enzyme is the specific region where the substrate binds and the chemical reaction takes place.

• The active site of an enzyme is the part that stores energy for later use.

• The active site of an enzyme is the area where waste products are stored.

What is the lock and key model of enzyme-substrate interaction?

• The lock and key model describes the enzyme and substrate as being completely unrelated in shape

• The lock and key model refers to the enzyme wrapping around the substrate like a glove

• The lock and key model describes the specific and complementary fit between an enzyme's active site and its substrate, similar to how a key fits into a lock.

• The lock and key model suggests that the enzyme and substrate have no specific interaction

What is the induced fit model of enzyme-substrate interaction?

• The induced fit model suggests that enzymes and substrates have a rigid, unchanging interaction

• The induced fit model states that enzymes and substrates have a loose, unstable interaction

• The induced fit model proposes that enzymes and substrates do not interact at all

• The induced fit model proposes that the active site of an enzyme undergoes a conformational change upon binding to the substrate, resulting in a better fit between the enzyme and substrate.

What is enzyme specificity?

• Enzyme specificity refers to the ability of an enzyme to select a specific substrate but catalyze multiple reactions.

• Enzyme specificity refers to the ability of an enzyme to select a specific substrate and catalyze a specific reaction.

• Enzyme specificity refers to the ability of an enzyme to select any substrate and catalyze any reaction.

• Enzyme specificity refers to the ability of an enzyme to select multiple substrates and catalyze multiple reactions.

What is the optimal pH for most enzymes?

• The optimal pH for most enzymes is around 7, which is neutral.

• The optimal pH for most enzymes is 0, which is highly acidic.

• The optimal pH for most enzymes is 5, which is slightly acidic.

• The optimal pH for most enzymes is 14, which is highly alkaline.

What is the optimal temperature for most enzymes?

• The optimal temperature for most enzymes is around 50 degrees Celsius.

• The optimal temperature for most enzymes is around 37 degrees Celsius.

• The optimal temperature for most enzymes is around 0 degrees Celsius.

• The optimal temperature for most enzymes is around 100 degrees Celsius.

What is enzyme denaturation?

• Enzyme denaturation is the process of enhancing the enzyme's shape and function

• Enzyme denaturation is the process of improving the enzyme's efficiency and specificity

• Enzyme denaturation is the process in which an enzyme loses its shape and function due to changes in temperature, pH, or other environmental factors.

• Enzyme denaturation is the process of increasing the enzyme's stability and activity

large molecules created from DNA that are required for the structure, function, and regulation of the body’s cells, tissues, and organs

• protein

• enzyme

• substrate

• active site
