ADP Pi are a set of molecules that store energy for catabolism. Pi acts as a shuttle molecule to move energy from ATP to ADP. Energy from catabolism can be used directly for performing cellular work. ATP is a molecule that acts as an intermediary to store chemical energy for cellular work. True or false?

True

Explanation:

Adenosine triphosphate also known as ATP is a biological complex molecule that function as an energy carrier for storing and transferring energy. Therefore, it is also known as molecular unit of currency.

Energy released from catabolism stores in ATP in the form of phosphate bond.  

Energy released when a phosphate bond is broken. ATP releases energy and convert to ADP and AMP. So, it also acts as an intermediary to store chemical energy for cellular work.

Therefore, the given statement is true.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
