Official Answer

Glucose is oxidized to provide energy in human body in two ways: Aerobic respiration: C6H12O6+6O2ightarrow6CO2+6H2O+Energy(ATP)C_6H_{12}O_6 + 6O_2 ightarrow 6CO_2 + 6H_2O + Energy (ATP) Anaerobic respiration: C6H12O6ightarrow2C2H5OH+2CO2+Energy(ATP)C_6H_{12}O_6 ightarrow 2C_2H_5OH + 2CO_2 + Energy (ATP)

Marking Scheme

  • 1/2 for each equation
  • 2/1 for each product

Hint

Recall the equations for aerobic and anaerobic respiration.

Quick Oral Answer

Glucose is oxidized to provide energy in human body in two ways: Aerobic respiration and Anaerobic respiration. Aerobic respiration produces more energy and occurs in the presence of oxygen, while anaerobic respiration produces less energy and occurs in the absence of oxygen.

Analysis & Explanation

The question requires the student to recall the two ways in which glucose is oxidized to provide energy in human body. The student should be able to write the equations for aerobic and anaerobic respiration and identify the products formed in each case.

Common Mistakes

  1. 1Writing only one equation
  2. 2Not mentioning the products formed

Interesting Facts

Aerobic respiration produces more energy than anaerobic respiration.

Anaerobic respiration occurs in the absence of oxygen.
