Cell Energy Flow Chart Photosynthesis And Cellular Respiration
Introduction
Cellular respiration and photosynthesis are two interconnected processes that occur in all living organisms. These processes are responsible for the flow of energy through the cells of living organisms. In this article, we will explore the cell energy flow chart of photosynthesis and cellular respiration.
Photosynthesis
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigment. This process takes place in the chloroplasts of the plant cells. The products of photosynthesis are glucose and oxygen.
Cellular Respiration
Cellular respiration is the process by which living organisms produce energy by breaking down glucose and releasing carbon dioxide and water. This process takes place in the mitochondria of the cells. The products of cellular respiration are ATP, carbon dioxide, and water.
Energy Flow Chart
The energy flow chart shows the interconnection between photosynthesis and cellular respiration. The flow of energy starts with the absorption of light energy by chlorophyll pigment in photosynthesis. This energy is used to synthesize glucose and oxygen. The glucose produced is then used in cellular respiration to produce ATP, carbon dioxide, and water.
Photosynthesis Process
The photosynthesis process is divided into two stages: light-dependent reactions and light-independent reactions. In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll pigment, and oxygen is produced as a by-product. In light-independent reactions, CO2 is fixed by the enzyme Rubisco to form glucose.
Cellular Respiration Process
Cellular respiration is divided into three stages: glycolysis, Krebs cycle, and the electron transport chain. In glycolysis, glucose is broken down into two pyruvate molecules and two ATP molecules are produced. In the Krebs cycle, pyruvate is broken down into CO2, and ATP, NADH, and FADH2 are produced. In the electron transport chain, the energy from NADH and FADH2 is used to produce ATP.
Photosynthesis and Cellular Respiration Relationship
Photosynthesis and cellular respiration are two interconnected processes that rely on each other for the flow of energy. The glucose produced by photosynthesis is used in cellular respiration to produce ATP. The oxygen produced by photosynthesis is used in cellular respiration as an electron acceptor in the electron transport chain.
Importance of Photosynthesis and Cellular Respiration
Photosynthesis and cellular respiration are important processes for life on earth. They are responsible for the flow of energy through living organisms. Without these processes, life on earth would not exist.
Conclusion
The cell energy flow chart of photosynthesis and cellular respiration shows the interconnection between these two processes. Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce ATP, carbon dioxide, and water. These two processes are essential for the flow of energy through living organisms and for life on earth.
