Answer:
Fructose, galactose.
Question 3:
State the word equation for aerobic respiration.
Answer:
Glucose + oxygen —> carbon dioxide + water + energy
State the word equation for aerobic respiration.
Answer:
Glucose + oxygen —> carbon dioxide + water + energy
Question 4:
Describe the processes involved in aerobic respiration to produce energy.
Answer:
Sugar breakdown (glycolysis) takes place in the cytoplasm. Glucose (6-carbon) is broken down to two pyruvate molecules (3-carbon). In the next stage, pyruvate is oxidised through a series of reactions to produce carbon dioxide, water and energy. This stage takes place in the mitochondrion.
