  3. Prevents dehydration

  4. More than one correct answer
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water is the medium for all metabolic processes in living organisms, acting as a solvent for biochemical reactions. While it helps prevent dehydration, its primary biological role is facilitating the chemical reactions that sustain life.

Which of the following represents the metabolic anti-transparent?

  1. PMA
  2. $CO _2$

  3. Aspirin

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

PMA (phorbol myristate acetate) acts as a metabolic activator or tumor promoter, stimulating various cellular processes. It is often described as 'anti-transparent' in the sense of being a metabolic stimulant. CO2 and aspirin have different primary roles in metabolism.

  2. Translation

  3. Splicing

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

RNA plays a central role in various life processes, including the synthesis of proteins (translation), the processing of pre-mRNA (splicing), and various regulatory metabolic functions. Therefore, all listed processes involve RNA.

Respiration is a

  1. Anabolic process

  2. Deamination process

  3. Catabolic process

  4. Both A and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The breaking of the C-C bonds of complex compounds through oxidation within the cells, leading to the release of a considerable amount of energy is called as respiration. As carbon-carbon covalent bonds are broken, it is a catabolic process. Respiration involves the synthesis of energy in form of ATP. The synthesis of ATP leads to the formation of several covalent linkages of phosphates. There is synthesis which are included in the anabolic processes.

Thus, the correct answer is option D.

Catabolic and anabolic pathways are often coupled in cell because

  1. Both the paths have the same energy

  2. The free energy released from one pathway is used to drive other

  3. The intermediates of a catabolic pathway are used in the anabolic pathway

  4. Their enzymes are controlled by their activators and inhibitors.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Anabolic pathways are those that require energy to synthesize larger molecules. Catabolic pathways are those that generate energy by breaking down larger molecules. Both types of pathways are required for maintaining the cell's energy balance.
  • Catabolic and anabolic pathway are coupled because catabolic reactions furnish the energy required for anabolism. Catabolic reactions transfer energy from complex molecules to ATP. Anabolic reactions transfer energy from ATP to complex molecules.
  • Hence Catabolic and anabolic pathways are often coupled in the cell because the free energy released from one pathway is used to drive other.
  • So, the correct answer is 'the free energy released from one pathway is used to drive other'.

Muscle tissue growth : anabolic process : : .......... : catabolic process.

  1. Digestion

  2. Secretion

  3. Regulation

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Muscle tissue growth is an anabolic process. There is respiration reactions carried out in the muscles which provide energy in the form of ATP. This liberated energy helps the muscles to relax and contract. Thus, the muscles tissue show growth due to anabolic process. 

The process of digestion is considered as the catabolic process. There is break down of the complex food into simpler compounds. These simpler molecules can be easily absorbed by the cells of the body. 
Thus, the correct answer is option A. 

Multiple choice bio-chemistry organization of life concept of metabolism metabolism in animals metabolism

Conversion of polysaccharide to monosaccharide is known as

  1. Anabolic reaction

  2. Catabolic reaction

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The catabolic processes are the reactions in which the large complex molecules are broken down to produce smaller organic molecules. The polysaccharide which is a complex molecule is broken down to from many small monosaccharide molecules. For example, glycogen is broken down to produce glucose molecules. 

Thus, the correct answer is option B. 

Multiple choice bio-chemistry organization of life concept of metabolism metabolism in animals metabolism

Which of the following activity is catabolic in nature?

  1. Cell repair

  2. Protoplasm synthesis

  3. Degradation of amino acid in liver

  4. Conversion of glucose to glycogen
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Catabolism involves the breakdown of a substance, often to release energy or during excretion for removal of waste. Degradation of amino acids in the liver is such an example where amino acids are broken down into inorganic substituents for recycling or removal.

Cell repair, protoplasm synthesis and conversion of glucose to glucose are all examples of anabolism which involves the synthesis of a product.
So the correct answer is 'Degradation of amino acids in the liver'.

Formation of nucleotide is a

  1. Anabolic reaction

  2. Catabolic reaction

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The nucleotides can be formed by two paths. When the nucleotide is formed due to the breaking of the bonds in the RNA and DNA, this process is an example of a catabolic process. When the nucleotides are formed from the nucleosides and nitrogenous bases, then this is an example of an anabolic process. 

Thus, the correct answer is option C.
