Cellular Respiration & ATP Reading

Read part IV and answer the questions that follow (6 minutes)

STAMP

• In cells, this energy is stored in a high energy molecule called ATP.
• All cells make ATP in their mitochondria using the process of respiration.
• Ultimately all cellular energy for life on Earth is derived from the sun.
• Organisms that can produce their own energy (ATP) directly from the sun are called autotrophs and organisms that rely on consuming other organisms to make energy (ATP) are called heterotrophs.
