Metabolism Overview

What is the process by which cells break down glucose to produce ATP?

• Cell division

• Photosynthesis

• Cellular respiration

• Protein synthesis

Which organelle is responsible for carrying out cellular respiration in eukaryotic cells?

• Nucleus

• Chloroplasts

• Mitochondria

• Endoplasmic reticulum

What is the overall chemical equation for photosynthesis?

• 6CO2 + 6H2O + ATP -> C6H12O6 + 6O2

• 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• C6H12O6 + 6O2 -> 6CO2 + 6H2O

• spontaneous

• catabolic

• exothermic

• endergonic

What is the term for the building up of complex molecules from simpler ones?

• catabolism

• synthesis

• anabolism

• metabolism

Which type of metabolism involves the breakdown of complex molecules into simpler ones?
