IB Biology SL C1.2.4 Cell Respiration System Questions

Learn how enzyme-controlled respiration oxidizes organic compounds in steps, releasing energy for ATP production; explore oxygen use and metabolite data as evidence in IB Biology SL C1.2.4.

Exam points

Define cellular respiration as the enzyme-controlled release of energy from organic compounds.
Explain that carbon compounds are oxidized in steps so energy can be transferred to ATP.
Interpret oxygen-consumption and metabolite data as evidence of respiration and the organic compounds used.

[Maximum number: 2]

Describe cell respiration in terms of metabolism.

a. cell respiration is metabolism because enzymes control the reactions
b. energy is released from complex molecules to make ATP
c. respiration is catabolic (metabolism);
OR complex molecules become simpler;
OR
$\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6} \text { to } \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O}$
