Introduction
The POGIL (Process Oriented Guided Inquiry Learning) approach has been widely used in teaching science. One of the popular POGIL activities is energy transfer in living organisms, which covers topics such as photosynthesis, cellular respiration, and ATP synthesis. This article provides an answer key for the energy transfer in living organisms POGIL activity.
What is Energy Transfer?
Energy transfer is the movement of energy from one place to another. In living organisms, energy is transferred through different processes such as photosynthesis, cellular respiration, and ATP synthesis. The energy is transferred in the form of ATP (adenosine triphosphate), which is the energy currency of the cell.
Photosynthesis
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. The process involves the conversion of light energy into chemical energy in the form of ATP. The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2
Cellular Respiration
Cellular respiration is the process by which living cells obtain energy from organic molecules such as glucose. The process involves the breakdown of glucose into carbon dioxide and water, with the release of energy in the form of ATP. The equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP)
ATP Synthesis
ATP synthesis is the process by which ATP is produced in living cells. The process involves the transfer of energy from organic molecules such as glucose to ATP. The energy is used to add a phosphate group to ADP (adenosine diphosphate) to form ATP. The equation for ATP synthesis is: ADP + Pi + energy → ATP
