B) They may form either long, thin fibrous molecules or compact, rounded globular molecules.
C) They store genetic information for cellular metabolism.
D) They form through hydrolysis reactions.
E) a and b
Answers
Enzymes, which can catalyze chemical reactions, are a type of protein. Moreover, proteins can either be fibrous and insoluble in water like actin and myacin, or globular and soluble like hemoglobin. DNA, which stores the genetic information, is not made of proteins. Lastly, proteins are made through the translation of mRNA at the ribosomes.
I hope this helps!
Final answer:
Correct answer is Option E, which includes options A and B. Proteins can enhance specific chemical reactions as enzymes and can form diverse structures. Proteins do not store genetic information and do not form through hydrolysis reactions.
Explanation:
The correct answer to this question is Option E, which are options A and B. Proteins do indeed have the ability to enhance the rate of specific chemical reactions. These are known as enzymes. Another characteristic of proteins is their diverse structure, as mentioned in option B. They can form long, thin fibrous molecules like collagen or compact, rounded globular molecules like hemoglobin. However, they do not store genetic information (that is the function of DNA and RNA), nor do they form via hydrolysis reactions. Proteins are synthesized through a process called dehydration synthesis, not hydrolysis.

Answer : The structural formula of 2-pentyne is shown below.
Explanation :
Structural formula : In the structural formula, the bonding and type of bonds which holds the atoms in molecule together are shown.
The given name of compound is, 2-pentyne.
A suffix '-yne' present at the end of the name represent the alkyne group.
For the number of carbon atom, we use prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
In this compound, the parent chain is 5 membered and a triple bond is present at 2nd position of the parent chain.
Thus, the structural formula of 2-pentyne is shown below.
A. Speeds up
B. Reflects light
C. Slows down
D. Gains energy
Answers
Answer : The correct option is, C.
Explanation :
- Refraction : When light is passing from rarer medium to denser medium then the light bends towards the normal line due to change in the speed of the light.
- Reflection : When light ray falling on the surface then the refracted ray coming out from the surface. In reflection, the incident angle is equal to the reflected angle.
In a given diagram, refraction phenomenon is observed in which an incident angle of a light ray is and the refracted angle of a light ray is
which means the light bends towards the normal.
From this we can say that the light is passing through rarer medium to denser medium. In denser medium, the speed of light slows down.
