Only green plants and cyanobacteria can prepare their own food. 3. Plants prepare food by the process of Respiration. 4. During oxidation within a cell, all the energy contained in respiratory substrates is not released free into the cell, or in a single step. 5. Glucose and fruc

Step-by-step solution

All the energy required for life processes is obtained by oxidation of some macromolecules that we call food. Only green plants and cyanobacteria can prepare their own food; by the process of photosynthesis they trap light energy and convert it into chemical energy that is stored in the bonds of carbohydrates like glucose, sucrose and starch.,Glucose and fructose are phosphorylated to give rise to glucose-6- phosphate by the activity of the enzyme hexokinase
