Metabolism - chapter 6 -

What is the main purpose of metabolism in living organisms?

• To produce oxygen

• To perform photosynthesis

• To convert energy stored in molecules into usable energy for cellular processes

• To excrete waste products

What is the role of catabolic pathways in metabolism?

• To store energy

• To break down molecules and release energy

• To build complex molecules from simpler ones

• To synthesize proteins from amino acids

Which type of energy is associated with motion?

• Potential energy

• Chemical energy

• Kinetic energy

• Stored energy

What is the energy currency of the cell?

• Glucose
