3.3 Cellular Respiration
in AP Biology
Respiration breaks the fuel down, using oxygen and generating ATP. The waste products of this type of respiration, carbon dioxide and water (H2O), are the raw materials for photosynthesis.
3.2 Enzymes
in AP Biology
Enzymes speed up metabolic reactions by lowering energy barriers. Each enzyme has an optimal temperature and pH. Regulation of enzyme activity helps control metabolism.
3.1 Cellular Energy
in AP Biology
The totality of an organism’s chemical reactions is called metabolism. Metabolism is an emergent property of life that arises from orderly interactions between molecules.
