#Question id: 10788
#Unit 6. System Physiology – Plant
Phenyl ammonia lyase (PAL) involved in biosynthesis
of phenolic compound in plants. Following are some statements regarding the
action of PAL;
a) PAL catalyze conversion of phenyl alanine to p-coumaric
acid
b) PAL catalyzes the conversion of phenyl alanine into
trans-Cinnamic acid by elimination of an ammonia molecule
c) The activity of PAL is increased by environmental
factors, such as low nutrient levels, light, and fungal infection
d) PAL is situated at a branch point between primary
and secondary metabolism, so the reaction that it catalyzes is an important
regulatory step in the formation of many phenolic compounds
Which of the following combinations of above statement is true?
