Enzymes are the protein substances, which serve the role of catalyzing the ________
- A.
Biochemical reaction
- B.
Chemical reaction
- C.
Physical reaction
- D.
Biological reaction
Correct Answer
A. Biochemical reactionExplanation
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."Rate this question:

Is [When lead acetate is added to a solution of wool in caustic soda, a black precipitate is formed] true or false?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
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.Rate this question:

The sterile threads, strings, or stands specially prepared for use in surgery meant for sewing tissued together is called ________
Correct Answer
SuturesExplanation
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.Rate this question:

Following are the stages of the ergot cycle except:
- A.
Over wintering stage
- B.
Stage of sexual reproduction
- C.
Stage of sexual reproduction
- D.
Over summering stage
Correct Answer
D. Over summering stageExplanation
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.Rate this question:

Enzymes are the protein substances, which serve the role of catalyzing the ________ reaction.
Correct Answer
biochemicalExplanation
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.Rate this question:
