Answer 4

Question

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

The statement “The catalytic properties of an enzyme exist at its active site” is a true statement.

Explanation of Solution

The substrate in an enzyme-catalyzed reaction is the reactant reacting with the enzyme to give a back product. Substrate attaches to the active site of the enzyme for the catalysis. Therefore, the statement “The catalytic properties of an enzyme exist at its active site” is true.

Conclusion

The statement “The catalytic properties of an enzyme exist at its active site” is a true statement.

Whether the statement “Fats and oils are distinguished by their state of matter at room temperature” is true or false is to be stated.

Concept introduction:

Lipids are the water-insoluble compounds found in the living organisms. Lipids are parted into three classes (1) Fats, oils and phospholipids, (2) waxes, and (3) steroids.

All these compounds are insoluble in polar solvents like water because of the large presence of hydrophobic groups in them.

Expert Solution

Answer to Problem 60E

The statement “Fats and oils are distinguished by their state of matter at room temperature” is a true statement.

Explanation of Solution

Fats and oils are the triesters of long-chain carboxylic acids known as fatty acids. The ester is formed from simple alcohol glycerol. The fats and oils are also referred to as triacylglycerols. The fats at room temperature are solid while the oils are liquid at room temperature. Therefore, the statement “Fats and oils are distinguished by their state of matter at room temperature” is true.
