Fatty acids are activated to acyl-CoAs and the acyl group is further transferred to carnitine because:

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. acyl-carnitines readily cross the mitochondrial inner membrane, but acyl-CoAs do not.

  2. acyl-CoAs easily cross the mitochondrial membrane, but the fatty acids themselves will not.

  3. carnitine is required to oxidize NAD+ to NADH.

  4. fatty acids cannot be oxidized by FAD unless they are in the acyl-carnitine form.

Following are certain strategies used by pathogen to attack over the host plant that describe plant-pathogen interactions:

                      I                                                                                             II

A. Necrotrophic pathogens                              i) most of the plant tissue remains alive and only minimal cell damage can be observed, as the pathogens feed on substrates provided by their host

B. Biotrophic pathogens                                 ii) In which the host cells are kept alive as described for biotrophic  Pathogens and followed by a necrotrophic stage, in which the pathogens can cause extensive tissue damage

C. Hemibiotrophic pathogens                         iii) attack their host by secreting cell wall–degrading enzymes or toxins, which eventually kill the affected plant cells, leading to extensive tissue maceration. This dead tissue is then colonized by the pathogens and serves as a food source
