Official answer

C_6H_{12}O_6 + 6O_2 ightarrow 6CO_2 + 6H_2O + Energy (ATP)

aerobic respiration

anaerobic respiration

glucose

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

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

Common mistakes

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

Analysis and 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.

Interesting facts

$Aerobic respiration produces more energy than anaerobic respiration.$

$Anaerobic respiration occurs in the absence of oxygen.$
