Solution:
12. (A) Glucose is an example of monosaccharides.They have molecular formula C6H12O6.Glucose is also known as dextrose.Glucose contain six carbon atom and aldehyde group.
13.(B)It is a lipid molecule.It play an important role in maintaining structure of cell walls.
14.(B) Accoding to gibbs,reaction always proceed in direction where free energy is decreasing.
15.(e) Enzyme play an important role in coupling energy giving and energy absorving reaction.Brings energetically favorable and non energetic favourable reaction together.
16.(a) Plants convert solar energy into chemical bond energy and animal convert chemical bond energy into heat energy.
17.(D)ATP.ATP is the source of energy for various chemical reactions.
18.(B) The catalyzed pathway in the reaction mechanism has lower activation energy and thus causes a higher reaction rate.
19.(a)Enzyme catalyzed reactions generally generate a metabolic pathway.As all metabolites are controlled by enzyme controlled chemical reactions.
