What is the flow of energy in photosynthesis and cellular respiration?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
What is the flow of energy in respiration?
During cellular respiration the energy flow begins with the consumption or using of glucose created from photosynthesis. This glucose is then transported to the mitochondria with the cells to be converted or changed into ATP energy.
How does energy flow through the cycle of photosynthesis?
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement.
What is the story of photosynthesis and respiration?
Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
What is difference photosynthesis and respiration?
The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.
How does carbon flow between photosynthesis and cellular respiration?
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
What happens to energy during photosynthesis?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
How are photosynthesis and respiration related apex?
Both depend on each other. In photosynthesis glucose is formed and oxygen is released as by product. In respiration glucoseis oxidised by the use of oxygen. The carbondioxide is raw material for photosynthesis.
How does energy flow?
Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level. Producers are always the first trophic level, herbivores the second, the carnivores that eat herbivores the third, and so on.
What are the major stages in photosynthesis?
Photosynthesis takes place in two sequential stages:
- The light-dependent reactions;
- The light-independent reactions, or Calvin Cycle.
