D. Carboxylation of Macromolecules
Which of the following is not true?
(1) All the energy required for life processes is obtained by oxidation of some macromolecules that we call food
(2) Only green plants and cyanobacteria can prepare their own food
(3) The result of the photosynthesis is such that the light energy is trapped in the form of mechanical energy
(4) Not all the cells, tissues and organs photosynthesise in green plants

Respiration is
(1) Breaking of a type of bonds like ionic or non ionic of complex compounds through oxidation within the cell by utilizing bulk of energy
(2) Breaking of C-C bonds of simple molecules through hydrolysis within the cell by releasing energy
(3) Breaking of C-C bonds of complex molecules through oxidation within the cell to release considerable amount of energy
(4) Breaking of C-C bonds of complex molecules through hydrolysis within the cell by releasing energy
