The answer is 3468 kcals. Protein and carbohydrates both contain 4 calories per gram, while fat provides 9 calories per gram.
Carbohydrate = 240 gms x 4 = 960 cal Protein = 132 x 4 = 528 cal Fat = 220 x 9 = 1980 cal
Total : 960+528+1980 = 3468 calories
Cellular respiration is the process that take place in the mitochondrion of a cell, it involves use of glucose from photosynthesis to produce energy in form of ATP and formation of CO2 and water. In this case, the Carbon dioxide formed passively diffuses out of the cell and Oxygen is pumped in and forces CO2 out. In this process oxygen acts as a electron acceptor.
