,• A hummingbird needs energy to maintain prolonged flight.
The bird obtains its energy from taking in food and
transforming the energy contained in food molecules into
forms of energy to power its flight through a series of
biochemical reactions.
,Life and Energy Transformation
• Life is highly ordered.
• Life requires energy to maintain order.
• ATP is the energy currency.
• ATP is the only spendable energy.
, Life and Energy Transformation
• Photosynthesis reaction, cellular respiration
reaction, all life is the interplay of these two
organelles: chloroplasts and mitochondria.
• Human complexity functions to serve mitochondria
— lungs, circulatory system, digestive system.
