The following two chemical reactions are supposed to indicate a certain process occurring in the green plants under two different conditions:
(a) C6H12O6 + 6O2 → 6CO2 + …… + 38ATP
(b) C6H12O6 → …… + 2CO2 + 2ATP
- Fill in the blanks of each reaction
- Name the process represented by the two chemical equations
- What are the conditions under which the two reactions (a) and (b) are occurring?
Answer
- (a) 6H2O
(b) 2C2H5OH - (a) The process observed in this chemical reaction here is aerobic respiration
(b) The process observed in this chemical reaction is anaerobic respiration - The reaction occurring in (a) can take place only in the presence of oxygen as it is aerobic respiration. The reaction occurring in (b) can take place even in the absence of oxygen as it is anaerobic respiration.
