Enzymes are the protein substances, which serve the role of catalyzing the ________

Biochemical reaction
Chemical reaction
Physical reaction
Biological reaction

Correct Answer

A. Biochemical reaction

Explanation

Enzymes are specialized protein substances that act as catalysts, speeding up biochemical reactions in living organisms. They achieve this by lowering the activation energy required for the reaction to occur. Unlike physical or chemical reactions, biochemical reactions involve the transformation of organic molecules, such as carbohydrates, lipids, and proteins, within cells. Therefore, the correct answer is "Biochemical reaction."

Is [When lead acetate is added to a solution of wool in caustic soda, a black precipitate is formed] true or false?

True
False

Correct Answer

A. True

Explanation

When lead acetate is added to a solution of wool in caustic soda, a black precipitate is formed. This statement is true. Lead acetate is known to react with wool in caustic soda to form a black precipitate, which is commonly used in the laboratory as a test for the presence of sulfur-containing compounds in organic substances.

The sterile threads, strings, or stands specially prepared for use in surgery meant for sewing tissued together is called ________

Correct Answer
Sutures

Explanation
Sutures are sterile threads, strings, or strands that are used in surgery to sew tissues together. They are specially prepared for this purpose and are an important part of the surgical procedure. Sutures are used to close wounds, incisions, or surgical sites, allowing the tissues to heal properly. They are made from various materials, such as silk, nylon, or absorbable materials, depending on the specific needs of the surgery. Sutures play a crucial role in ensuring the success of surgical procedures by promoting wound healing and preventing infection.

Following are the stages of the ergot cycle except:

Over wintering stage
Stage of sexual reproduction
Stage of sexual reproduction
Over summering stage

Correct Answer

A. Over summering stage

Explanation

The given answer is "Over summering stage". The ergot cycle consists of several stages, including the over wintering stage, stage of sexual reproduction, and stage of asexual reproduction. However, there is no stage called "over summering stage" in the ergot cycle. This is why it is the exception among the given options.

Enzymes are the protein substances, which serve the role of catalyzing the ________ reaction.

Correct Answer
biochemical

Explanation
Enzymes are protein substances that serve the role of catalyzing biochemical reactions. They act as biological catalysts, speeding up the rate of chemical reactions in living organisms. Enzymes are highly specific, meaning they can only catalyze a particular reaction or a group of closely related reactions. They do this by binding to the reactant molecules, called substrates, and facilitating the conversion of these substrates into products. Without enzymes, many biochemical reactions would occur too slowly to sustain life. Therefore, enzymes play a crucial role in various metabolic processes and are essential for the functioning of living organisms.
