Document Summary
Lecture 8: energy metabolism: autotrophs make food from sunlight (plants, heterotrophs use the food to do work (beaver) Food (chemical bond energy) +o2 work, heat, co2. Atp is the main currency in the cell. Mitochondria demands for us to eat and get energy. When you are small and need to grow, you need food (mom beaver getting food for baby beaver) Other animal thing - using mechanical angry to scrape away algae (autotroph) and taking their energy and using it. Babies with little organization have to transform to a highly organized adult (requires energy) 2% of our protein every day is changed. Organized systems change in to disorganized systems in isolated systems. Us we are an organized system that require input from outside to maintain organization. Energy metabolism: the set of processes by which organisms: Energy exists in different forms: chemical energy. When the atoms within molecules are rearranged, chemical energy may be required, or it may be released.
