In a closed system, such as the universe, this energy is not consumed but transformed from one form to another. One example of an anabolic pathway is the synthesis of sugar from CO2. Consequently, metabolism is composed of these two opposite pathways: Anabolic and catabolic pathways: Anabolic pathways are those that require energy to synthesize larger molecules. Some organisms capture energy from the sun and convert it into chemical energy in food; others use chemical energy from molecules they take in. What is Photosynthesis? for example, you sweat to release water because you're hot since your muscles are contracting. %%EOF xref By David Knuffke. Organisms use energy to survive, grow, respond to stimuli, reproduce, and for every type of biological process.
